Abstract

Circumscription of the large genus Pultenaea Sm. has been contentious since shortly after description. We draw on recently generated phylogenomic data to provide a fully resolved phylogeny of Pultenaea and related genera based on near-complete species level sampling for the genus. Phylogenomic data divide Pultenaea sens. lat. into five independent lineages, corresponding to previously identified clades, that we recognise as distinct genera. Pultenaea sens. str. contains most of the currently recognised species and as circumscribed here, all of the species are endemic to eastern Australia except for P. tenuifolia R.Br. & Sims that extends across the Nullarbor into Western Australia. The genus Euchilus R.Br. is reinstated for eight species, all endemic to south-west Western Australia except for E. elachistus (F.Muell.) R.L.Barrett & Orthia that also occurs in South Australia. Three new genera are described, with all of the constituent species endemic to south-west Western Australia: Grievea R.L.Barrett, Clugston & Orthia, with two species, Jennata R.L.Barrett, Clugston & Orthia, with nine species and Loricobbia R.L.Barrett, Clugston & Orthia with six species. Pultenaea adunca Turcz. remains unplaced but we exclude this species from our concept of Pultenaea. Twenty-one new combinations are made: Euchilus aridus (E.Pritz.) R.L.Barrett & Orthia, E. calycinus subsp. proxenus (Orthia & Chappill) Orthia & R.L.Barrett, E. daena (Orthia & Chappill) Orthia & R.L.Barrett, E. elachistus (F.Muell.)

Introduction

Pultenaea Sm. was originally established based on a single species, P. stipularis Sm. (Smith 1794). James Edward Smith, an English nurseryman of note, had a particular interest in Australian peas and named many of the genera currently recognised in the tribe Mirbelieae (Smith 1794, 1798, 1805, 1808a, 1808b, 1808c). In the first decade after the genus was named, another 15 species were added (Schrader and Wendland 1797; Wendland 1798, 1799; Willdenow 1799; Andrews 1803, 1804; Ventenat 1804; Labillardière 1805; Persoon 1805; Smith 1805) but only nine of these remain in the genus as currently circumscribed. In an early review of genera allied to Pultenaea, Smith’s Decandrous Papilionaceous Plants, Smith (1805, p. 503) remarked that:

It is scarcely necessary to observe, that many plants have been forced into Pultenaea that have little to do with it. I mean not to censure those who have done so, but rather to approve of it, unless they had felt themselves competent to establish new genera on solid grounds.

These words hold true today and both sentences carry a unique weight of history. Many species have been named in Pultenaea that are currently placed in other genera. However, many genera currently recognised in Mirbelieae had also already been named by this time. Subsequently named genera in Mirbelieae are: Oxylobium Andrews (Andrews 1807); Euchilus R.Br., Eutaxia R.Br., Gastrolobium R.Br. and Podolobium R.Br. (Brown 1811); Jacksonia R.Br. ex Sm. (Smith 1811); Isotropis Benth., Leptosema Benth. and Phyllota (DC.) DC. ex Benth. (Bentham 1837); Latrobea Meisn. (Meisner 1848); Urodon Turcz. (Turczaninow 1849); Euchilopsis F.Muell. (Mueller 1882); Almaleea (Crisp and Weston 1991); and Stonesiella (Crisp et al. 1999). Smith’s name Daviesia reticulata Sm., long included in Pultenaea, finally has a home in our new genus, Loricobbia R.L.Barrett, Clugston & Orthia.

This paper originated at the 150 Conference held in Melbourne in September 2003 (Barrett et al. 2005), where phylogenetic data generated by Lindy Orthia and colleagues were presented in a session on generic concepts in the Australian flora. Even at that time, the urgent need to generate additional data in the hope of resolving critical relationships in the tribe Mirbelieae was recognised. Orthia et al. (2005a, 2005b, 2005c) highlighted that the trend for placing species in Pultenaea over the preceding 200 years had clearly rendered the current concept of Pultenaea paraphyletic. However, the phylogeny of the clades recovered could not be resolved for lack of support for the topology recovered. Definition of Pultenaea has remained challenging largely due to the lack of diagnostic characters for the genus, particularly following the broad concept adopted by Bentham (1864), who openly acknowledged that the concept may not have been a natural one. Nevertheless, Orthia et al. (2005c) did identify clear morphological clades within the Western Australian species placed in Pultenaea at that time that correlate well with clades identified in our phylogenetic analyses (Table 1).

Morphology, phylogenetics and classification

The seminal work of Sands (1975) recognised that variation within Pultenaea, as defined at the time, was equivalent to that of numerous recognised genera within what is currently recognised as the tribe Mirbelieae (Crisp and Weston 1987, 1995). Crisp and Weston (1987) identified a potential synapomorphy for Pultenaea: scarious, keeled stipules that are fused behind the petiole. This conclusion stimulated further research that resulted in the recognition of two new genera, Almaleea and Stonesiella, and the transfer of some species to Eutaxia and Urodon (Crisp and Weston 1987, 1995; Crisp et al. 1999; Wilkins et al. 2010). Crisp and Weston (1987) also noted that the Western Australian species Pultenaea ericifolia did not have fused stipules.

Most of the species formerly included in Pultenaea in Western Australia (16 of 24) do have free stipules (Orthia et al. 2005c). Orthia et al. (2005c) list 17 Western Australian species, however, the record of P. juniperina Labill. appears to be based on a cultivated plant and that of P. vestita R.Br., an erroneous identification, sometimes being confused with Jennata indira subsp. monstrosita (Orthia) Orthia & R.L.Barrett due to the dense indumentum on the leaves that is otherwise unusual in this segregate genus. Pultenaea craigiana C.F.Wilkins, Orthia & Crisp was described as an additional species from southern Western Australia (Wilkins et al. 2009). Pultenaea linearifolia Strid, described among diverse ‘novelties’ by Strid (1987) and not mentioned in subsequent literature, was first synonymised with P. adunca (Green 1987) and later with Dillwynia divaricata (Turcz.) Benth. (Western Australian Herbarium, FloraBase, see http://florabase.dpaw.wa.gov.au/).

We present a new classification of Pultenaea in the sense of Orthia et al. (2005c), recognising five genera (and removing two other anomalous species) based on comprehensive analyses of phylogenomic data using the Angiosperms353 nuclear bait kit (Clugston, Barrett, Murphy, Renner, Weston, Cook, Jobson, Lepschi and Crisp, unpubl. data; Fig. 1).

Lineage evolution and generic concepts

Plant diversity is high in both southwestern and southeastern Australia. This is particularly high in heath communities, and banksia and eucalypt woodlands, the primary habitats for species in the Mirbelia clade. The floras of both regions are highly distinct in many ways, yet also share many connections that are often >25 million years old (Bickford et al. 2004; Crisp et al. 2004; Crisp and Cook 2009; Nge et al. 2020, 2021; Tian et al. 2024) and many of these evolutionary connections predate the aridification of Central Australia and uplift of the Nullarbor Plain. Sister genera (and infrageneric groups) are commonly separated across the Nullarbor divide therefore definition of distinct clades as genera in the east and west is not an uncommon situation.

In Mirbelioid peas, there are several reasons for recognising eastern and western clades as distinct genera in specific cases. Stability of names is promoted by the separation of the western Pultenaea clades, as the genus would otherwise need to be expanded to include Almaleea, Stonesiella and Eutaxia to remain monophyletic. Inclusion of these three genera in Pultenaea would also reduce rather than improve morphological diagnosability of the genus (Crisp and Weston 1991; Crisp et al. 1999; Crisp and Cook 2003a, 2003b; Chappill et al. 2007).

Orthia et al. (2005a, 2005b) provide a detailed discussion of possible relationships within the Pultenaea group relative to the Mirbelia clade of Mirbelieae (as defined by Crisp and Cook 2003b) but the data available unfortunately failed to resolve key relationships between the major clades. The precautionary principle has been applied for the last 20 years and taxonomists have refrained from proposing generic changes within Mirbelieae during that time.

Coincident with a post-doctoral fellowship grant from the Australian Biological Resources Study, the Genomics for Australian Plants (GAP) initiative provided support that enabled species-level sequencing for most genera of the Mirbelia clade using the Angiosperms353 targeted bait kit and downstream data processing on the GADI server (Johnson et al. 2018; McLay et al. 2021; Nauheimer et al. 2021; Baker et al. 2021, 2022; Jackson et al. 2023; Simpson et al. 2024). This enabled unprecedented testing of relationships within Mirbelieae, especially at genus level. In contrast to early Sanger sequence-based analyses, our results resolved almost every node in the reconstructed phylogeny with a high level of confidence, enabling a robust classification to be developed (Clugston, Barrett, Murphy, Renner, Weston, Cook, Jobson, Lepschi and Crisp, unpubl. data).

The GAP initiative partnered with the Plant and Fungal Tree of Life (PAFTOL) project led by the Royal Botanic Gardens, Kew, to create a genus-level phylogenetic framework for Angiosperm diversity (Baker et al. 2021, 2022; Jackson et al. 2023; Simpson et al. 2024). The most significant combined output from PAFTOL and GAP has been a new global phylogeny including over 50% of angiosperm genera and almost all genera of Mirbelieae (Zuntini et al. 2024). The structure of this tree is consistent with the topology presented in Fig. 1 except for the placement of Urodon that may be anomalous in the PAFTOL tree due to low gene recovery. Combined with our present results, these papers are a testament to the broad utility of the Angiosperms353 targeted bait kit for phylogenetic resolution.

While we have had to wait 20 years for the generation of detailed genomic data for the tribe, we are gratified that new data remove the significant uncertainty that surrounded relationships within the tribe based on only three markers. We are now confident of phylogenetic relationships within the broader Pultenaea clade and can move forward.

Our aim has always been to minimise the number of taxonomic changes required, while circumscribing genera that are recognisable by morphological characters. Translating these data into generic concepts, acceptance of Almaleea, Stonesiella and Eutaxia speaks of the utility of these groups as natural, diagnosable units, and offers a logical reason for the recognition of additional Western Australian clades that are also morphologically diagnosable, at generic rank. All the genera in the core Pultenaea clade (EuchilusPultenaea in Fig. 1) are essentially geographically isolated in either eastern or western Australia, with only two variable species crossing the Nullarbor, one in each direction (Orthia et al. 2005c). The recognition of four additional genera highlights the uniqueness of the Western Australian biodiversity hotspot and adds three endemic genera to this region. The bush-pea genus Pultenaea sens. str. is essentially restricted to southeastern and eastern Australia and can now be readily morphologically defined.

This neat biogeographical separation is convenient for the communication of new generic concepts as all but two species in Western Australia are here transferred to other genera, therefore the past concept of Pultenaea becomes in consequential in that state. In eastern Australia, the well-known genus Pultenaea is retained entirely, except for a single species in South Australia (Craigie and Lang 2014) that belongs in Euchilus. As only 24 species are moving to one reinstated and three new genera, we hope that the degree of nomenclatural stability enabled by this minimal approach to taxonomic change will increase the likelihood of acceptance of the genera we propose to recognise.

Biogeography

East–west disjunctions point to vicariance events early in the evolution of the Mirbelia clade (Crisp and Cook 2003b; Barrett et al. 2021), likely preceding speciation within the genera recognised here. Vicariance events are estimated to have occurred between 12 and 20 Ma (Crisp et al. 2004), and may have promoted speciation within individual clades. This may possibly have been associated with the onset of aridification across inland Australia and uplift of the Nullarbor Plain. Further speciation is subsequently likely to have occurred within the current range area of these clades.

Separation of clades recognised here as genera may also have been assisted by chromosomal change, as most of the major clades within Mirbelieae have distinct chromosome numbers (see Sands 1975; Keighery 1984). Chromosomal arrangement may have been a driver of generic separation during a period of rapid radiation as such changes commonly form complete breeding barriers (de Storme and Mason 2014). Such changes may have occurred in response to changing climates, concurrent with the onset of aridification in Australia (Crisp et al. 2004; Crisp and Cook 2009).

Segregate genera

In arriving at what we consider to be the most appropriate generic boundaries, we assessed both phylogenetic relationships and the ease with which these related groups can be identified using morphological characteristics. Comparative morphological data for the Western Australian species previously included in Pultenaea and the sister genera are presented in Table 2. Euchilus R.Br. is reinstated for eight species with distinctively enlarged upper calyx lobes, seven of which are endemic to south-west Western Australia, the eighth extending across the Nullarbor into South Australia. Nine species, a number of which form a poorly defined complex, are recognised as a new genus, Jennata R.L.Barrett, Clugston & Orthia. These species all share a head-like inflorescence and strongly incurved (semi-terete) leaves. Two species whose relationships have been uncertain are here placed in a new genus, Grievea R.L.Barrett, Clugston & Orthia, and the presence of fused stipules in these species may represent a reversal of the character state in that clade.

A In some species such as E. elachistus, a secondary stipule-like structure is present between the stipules but this is usually hidden behind the petiole and therefore not commonly observed.

A clade of six species recovered as sister to Latrobea has been included in Pultenaea for most of the history (Loricobbia reticulata being the sole exception, having first been described as Daviesia reticulata and also combined as Jacksonia reticulata (Sm.) DC.). None of these species have ever been placed in Latrobea, despite largely sympatric distributions. This provides support for the recognition of these two lineages as separate genera based on historical usage. We describe this distinctive lineage as the new genus Loricobbia R.L.Barrett, Clugston & Orthia and diagnostic characters distinguishing the two genera are provided in Table 3.

The enigmatic species Pultenaea adunca Turcz. unfortunately remains unplaced in this classification, as no material was available for inclusion in the phylogenomic study. We are not confident to place this species within any genus based on morphology and available Sanger sequence data. Pultenaea adunca may be best placed in Almaleea or Grievea where the alliance clearly lies (Table 2) or possibly in a novel genus and additional studies are underway. We accept P. tenuifolia R.Br. as the only species of Pultenaea (as we here define the genus) that is native to Western Australia, though the main distribution is in eastern Australia and application of this name to Western Australian populations is worthy of further study.

Current taxonomy

We recognise that significant revision of species concepts within Pultenaea is still required (Renner et al. 2022; Telford et al. 2022; Barrett et al. 2024). We hope that settling generic boundaries will also encourage the description of novel species in remaining species complexes in Pultenaea and in the segregate genera recognised here.

Materials and methods

Full generic descriptions are provided below for Euchilus, Grievea, Jennata, Loricobbia and Pultenaea. Descriptions of these genera are aggregated based on those provided for species described in de Kok and West (2002, 2003, 2004), Orthia et al. (2005c) and Wilkins et al. (2010) with additional character assessment from specimens held at NSW and field photographs. References to previously published descriptions and illustrations are provided for each taxon and these are found under the respective combinations in Pultenaea unless otherwise indicated. Images of type specimens were located using the websites listed in Table 4.

Taxonomy

Euchilus R.Br. in W.T.Aiton, Hortus Kew 2nd edn, 3: 17 (1811)

[Orthographic variants include ‘Euchylus’, Poir. in F.Cuvier (ed.), Dict. sci. nat. 2nd edn, 15: 516–517 (1819); ‘Euchilos’ Spreng., Gen. pl. 1: 366 (1830)]

Pultenaea sect. Euchilus (R.Br.) F.Muell., Fragm. 1(1): 8 (1858). Type species: Euchilus obcordatus R.Br.

Open to dense, prostrate, procumbent or spreading to erect, multi-stemmed rounded shrubs, sometimes rhizomatous, 0.1–1.8 m high, 0.2–2.0 m wide. Stems and lower branches glabrous or glabrescent, or with persistent hairs. Branchlets apically with sparse to dense, appressed to ascending hairs, glabrescent, without tubercles, not spinescent. Stipules red–brown to red–black or black, persistent or breaking irregularly with age, the bases not fused but some stipule tissue remnant behind petioles, ovate to triangular, glabrous to sparsely hairy, 0.7–5.0 mm long. Leaves appressed to reflexed or divergent to ascending, decussate, sometimes in whorls of 3 (rarely 4) or spiralled; petiole subterete or pulvinate, not decurrent, 0.3–1.0 mm long; blade elliptic to obovate or oblong to linear, sometimes clavate to oblanceolate, straight or recurved, 1.1–12.9(–15.5) mm long, 0.5–4.0 mm wide, concolourous or discolourous, abaxial surface pale to olive, mid-green, bright green or grey–green to reddish-purple, vein and margins sometimes darker, midvein prominent or not, glabrous or with sparse, white, appressed or erect hairs, dense on new growth, smooth (rarely weakly verruculose); adaxial surface not concealed, glabrous or sparsely to densely hairy; margins flat to incurved or involute, or recurved; apex obtuse to rounded, mucronate or aristate, obcordate, slightly mucronate or sometimes recurved, sometimes minutely notched. Inflorescence with solitary axillary flowers, grouped towards apex, indeterminate. Inflorescence bracts absent. Peduncle absent. Flower subtending bracts scarious and pale to red–brown, commonly enlarged or herbaceous, leaf-like and green. Pedicels straight (sometimes twisted or tortuous), (0.1)–0.5–11.5 mm long. Bracteoles usually persistent slightly below the calyx, glabrous or sometimes sparsely hairy, scarious, dark red or red–brown, ovate to lanceolate, 0.8–6.0 mm long, 0.1–1.3 mm wide, apex acuminate. Hypanthium 0.6–1.8 mm long. Calyx glabrous to densely hairy, not ribbed; lobes asymmetrical, adaxial two larger, upper and lower lobes coherent for 25–100% of length; adaxial lobes elliptic to obovate, 2.0–7.8 mm long, apex usually obtuse, sometimes acute; middle and lateral abaxial lobes narrowly triangular to lanceolate, 1.0–4.8(–6.5) mm long; apex of abaxial lobes acute to acuminate. All petals vary in colour from yellow, gold, deep yellow or orange–yellow through pinkish to entirely red, apices often darker. Standard with a claw 1.0–2.2 mm long; lamina with flares of red following veins on upper surface surrounding a basal, ovate pale eye, circular to reniform, non-auriculate, 3.3–9.0 mm long, 3.9–9.7 mm wide, apex slightly emarginate. Wings held over keel, coherent for length or held apart, yellow with red markings towards apex, 3.0–7.2 mm long, 1.2–2.5 mm wide. Keel ±equal to the wings, lamina pale yellow to reddish with pale red apex, 2.8–7.5 mm long, 1.2–3.0 mm wide. Staminal filaments unequal, 2.5–5.5 mm long; anthers 0.2–0.6 mm long. Gynoecium with a stipe 0.2–0.6 mm long; ovary ovate, 1.2–3.5 mm long, laterally flattened, with dense, appressed hairs white, straight, evenly distributed or glabrous on body but hairy on margins; style straight to curved or hooked, 1.0–4.2 mm long, glabrous; stigma scarcely capitate. Pod not seen or elliptic or obovate, laterally flattened, apically dehiscent, 3.0–6.6 mm long, 2.0–3.7 mm wide, the outer surface glabrous or with sparse to dense hairs; the inner surface glossy, glabrous. Seed not seen or one per pod, reniform, round or ovate, smooth, pale brown to black with mottled brown markings or black spots, 1.3–2.6 mm long; aril absent or whitish. 2n = 16 or 18.

Diagnostic characters

Distinguished by the greatly enlarged upper calyx lobes, the lower three often reduced and obscure on first examination, similar in this respect to Euchilopsis linearis (Benth.) F.Muell. but this species has distant, alternate leaves (opposite or sometimes 3-whorled in Euchilus). Euchilus differs from Pultenaea in having free stipules. Euchilus differs from Jennata in opposite or sometimes 3-whorled (v. consistently spiralled) leaves; inflorescence bracts absent (v. present, scarious); upper calyx lobes greatly enlarged, elliptic to obovate (v. only slightly enlarged, triangular); standard claw short (v. long); ovary laterally compressed (v. ovoid); 2n = 16 or 18 (v. 14). Euchilus differs from Grievea in the free (v. fused) stipules; floral bracts herbaceous, leaf-like (v. absent or scarious); upper sepals fused for ~1/3 length (v. full length); keel ±equal to the wings (v. much smaller).

Etymology

The epithet is from the Greek eu- (well-) and cheilos (lipped), presumably in reference to the enlarged upper calyx lobes.

Distribution

Roe, Coolgardie and Eucla botanical districts in Western Australia. Euchilus elachistus (F.Muell.) R.L.Barrett & Orthia is the only species in the genus that extends across the Nullarbor Plain into South Australia, occurring on the Nullarbor Plain, Eyre Peninsula and Kangaroo Island (Fig. 2).

Note

We have chosen not to alter the termination of the species epithet daena with the transfer to Euchilus as the name originates from the Avestan language and Orthia et al. (2005c) took the primary meaning to be ‘that which was revealed’, rather than the Zoroastrian goddess of the same name. We therefore treat the epithet as an indeclinable noun.

Diagnostic characters

Differs from both Euchilus and Jennata in the fused (v. free, minute) stipules. Differs from both Almaleea and Stonesiella in the fused (v. free, minute) stipules; and floral bracts being absent or golden brown with a reduced leaf-like blade (v. herbaceous, leaf-like).

Distribution

A genus of two species, both endemic to the south coast of Western Australia (Fig. 4).

SB23029_F4.gif
Etymology

The new genus honours the late Brian John Grieve (1907–1997) who became the foundation Head of Botany at The University of Western Australia in 1947 and Professor of Botany in 1957 (Grieve 1975). He was initially co-author and later sole author of a popular series of field guides, How to Know Western Australian Wildflowers (Blackall and Grieve 1965, 1974, 1980, 1981, 1988; Grieve and Blackall 1975, 1982; Grieve 1982, 1998) that is yet to be superseded. (See also a biography in Orchard 1999.)

Notes

As postulated by Wilkins et al. (2009), Grievea craigiana is most closely related to G. brachytropis, the two species sharing fused stipules and floral and inflorescence characters, including the blunt, red-tipped calyx. The two species are readily distinguished by the involute leaf margins in G. craigiana, v. strongly recurved to revolute in G. brachytropis.

Inflorescence with solitary axillary flowers, grouped towards apex, indeterminate. Inflorescence bracts leaf-like or red–brown and scarious (rarely herbaceous and leaf-like), 2.5–9.5 mm long, with free bracteoles to 4.5 mm long, woolly. Peduncle absent. Pedicels absent. Bracteoles usually persistent slightly below the calyx, free or fused, glabrous to densely hairy, scarious, pale brown to red–brown, lanceolate, elliptic to falcate or ovate, 2.3–6.5 mm long, 0.3–1.4 mm wide, apex acute to acuminate.

Standard gold–yellow, yellow, apricot, orange, cream–pink, salmon–pink or vermillion, with a claw 2.5–6.2 mm long; lamina with a red line (sometimes radiating) surrounding a basal, ovate, yellow to white eye, circular to reniform, non-auriculate, 6.2–12.3 mm long, 5.0–11.0 mm wide, apex slightly emarginate. Wings often coherent or overlapping at apex, gold–yellow or pink to dark red, magenta or purple, with red at base, 5.6–10.2 mm long, 1.4–2.1 mm wide. Keel usually ±equal to the wings (but smaller in J. verruculosa, J. sp. Mt Lesueur), lamina red, dark red or black–red or sometimes pink at apex, grading to dark to bright red or pink at base, 5.8–9.5 mm long, 1.0–2.3 mm wide. Staminal filaments unequal, 4.0–7.8 mm long; anthers 0.3–0.6 mm long. Gynoecium without a distinct stipe or sometimes to 0.2 mm long; ovary 0.8–2.1 mm long, lateral section elliptic, velutinous, with hairs evenly distributed; style curved or hooked, 2.8–6.5 mm long, glabrous; stigma scarcely capitate or sometimes bulbous. Pod ovate, apically dehiscent, 3.5–6.0 mm long, 1.5–3.0 mm wide, the outer surface glabrous to densely hairy; the inner surface glabrous. Seed not seen or one per pod, round, ovate or obovate, smooth, light, dark or speckled brown with black spots, 2.0–2.4 mm long; aril whitish. 2n = 14.

Diagnostic characters

Jennata differs from Euchilus in having consistently spiralled (v. opposite or spiral, sometimes 3-whorled) leaves; leaves tightly involute, often appearing subterete with an adaxial groove; inflorescence bracts present, scarious or leaf-like (v. absent); upper calyx lobes only slightly to distinctly enlarged (but not enlarged to the extent found in Euchilus), narrow–triangular or deltate (v. greatly enlarged, elliptic to obovate); standard claw 2.5–6.2 mm long (v. 1–2.2 mm long); ovary ovoid (v. laterally compressed); 2n = 14 (v. 16 or 18). Jennata differs from Grievea in the free (v. fused) stipules; scarious (v. absent) inflorescence bracts; upper calyx lobes being narrowly triangular or deltate (v. falcate or rounded); and standard claw long (v. short; 2–2.3 mm long). Distinguished from Pultenaea by the prominent stipules that are not fused behind the petiole.

Distribution

A genus of approximately nine species (two not formally named), all endemic to the south coast of Western Australia (Fig. 6).

SB23029_F6.gif
Etymology

The genus name honours the late Jennifer (Jenny) Anne Chappill (1959–2006), who undertook extensive studies on the systematics of the legumes, publishing many new species (Chappill 1995; Doyle et al. 2000; Butcher and Chappill 2001, 2004; Crisp et al. 2005; Chappill et al. 2007, 2008; Wilkins and Chappill 2007a, 2007b, 2007c; Wilkins et al. 2010; https://www.anbg.gov.au/biography/chappill-jennifer-anne.html). The epithet is formed by a contraction of Jennifer (Jen) with the addition of the Latin nata (daughter), meaning that her work provided a foundation for the recognition of this genus. Jenny's legacy lives on through her research publications and the many individuals she trained in plant systematics at The University of Western Australia, including teaching R. L. Barrett as an undergraduate.

Note

Hollister and Thiele (2019) describe some Pultenaea species currently placed in Jennata (e.g. P. ericifolia) as having recurved rather than involute leaves, however this appears to be a character scoring error, presumably confusing the orientation of the leaves.

Key to Jennata taxa modified from Orthia et al. (2005c)

Name of uncertain placement

Pultenaea verruculosa var. recurva Benth., Fl. austral. 2: 129 (1864).

Type citation: ‘King George’s Sound, Collie.’

Note

Application of this name remains uncertain as authentic type material is yet to be traced. As relatively comprehensive searches for authentic material have been undertaken, either the citation or specimen label is possibly in error and refers to a collection attributed to ‘Bagster’ [Baxter], K 000978033! that is a specimen of Jennata empetrifolia from King George Sound, mounted with a specimen of J. verruculosa. Both collectors were active around King George Sound in the late 1820’s and confusion of attribution is entirely possible.

Calyx sparsely to densely hairy, not ribbed; all lobes ±equal in size, deltate to triangular, but upper lobes fused, hence calyx asymmetrical; adaxial lobes 1.8–3.7 mm long (1.9–7.0 mm long in L. reticulata); abaxial lobes 1.7–3.5 mm long (2.9–6.7 mm long in L. reticulata); apex of all lobes acute to acuminate. Standard with a claw 1.5–4.0 mm long; lamina yellow or gold with red or red–brown markings surrounding a basal, ovate to circular yellow eye, circular, non-auriculate, 7.0–15.0 mm long, 8.3–16.0 mm wide, apex slightly emarginate. Wings not coherent except sometimes near apex, yellow or gold with red base, 7.0–12.0 mm long, 1.2–4.7 mm wide. Keel ±equal to the wings but protruding at apex, lamina pale green or yellow with pink tinge, orange–brown or dark red–brown, 7.5–11.2 mm long, 2.3–4.8 mm wide. Staminal filaments ±equal, 5.0–9.0 mm long (~14 mm long in L. skinneri); anthers 0.5–1.2 mm long. Gynoecium sessile or with a stipe to 0.2 mm long; ovary 1.4–2.3 mm long, elliptic in cross section, velutinous, erect to spreading white hairs, evenly distributed; style straight to curved or hooked, 5.0–10.5 mm long, glabrous; stigma scarcely capitate. Pod ovate (sometimes almost orbicular), apically dehiscent, 4.5–11.0 mm long, 3.5–7.5 mm wide, the outer surface (sometimes glabrous) sparsely to densely hairy; the inner surface sparsely hairy. Seeds 2 per pod, obovate to reniform, smooth, dark brown to black or shiny black, 3.3–5.0 mm long; aril whitish. 2n = 8.

Diagnostic characters

Distinguished from Pultenaea by the presence of scarious inflorescence bracts (absent in Pultenaea) and ovoid (v. laterally flattened) ovaries that are hairy (v. glabrous) inside; and from Latrobea by the fused (v. free) stipules, scarious or leaf-like (v. leaf-like) floral bracts, two-lobed, asymmetrical (v. symmetrical) calyx lobes, emarginate (v. sagittate) standard petal, ovoid (v. laterally flattened) ovary, hairy (v. glabrous) inner surface of pods and 2n = 8 (v. 14); Table 3.

Distribution

A genus of six species, all of which are endemic to the south coast of Western Australia (Fig. 9).

Etymology

The new genus honours the late Lorraine (Lori) Cobb (1951–2008), who illustrated the legumes in Grieve (1998) and Wheeler (2002), and taught R. L. Barrett in plant systematics laboratory classes (see also Shepherd and Lyons 2009; https://asbs.org.au/wp-content/uploads/2023/08/08-june-135.pdf#page=10).

Notes

Grieve (1998) grouped many of these species together on the basis of ‘leaves rigid, concave, keeled or flat with conspicuous nerves.’ Pultenaea pinifolia and P. skinneri were keyed nearby based on the shared character of ‘Leaves recurved or revolute margins or channelled below.’

Typification

There are two syntypes that may well have been a single collection whenScott examined the material, with Williamson subsequently obtaining material from K that is currently held at MEL but we here designate the sheet at K as the lectotype as this history cannot be verified.

Note

Millar and Byrne (2013) found that this taxon has two distinct genetic clusters that likely warrant taxonomic distinction despite no clear morphological separation between the populations.

Hypanthium 0.6–3.6 mm long. Calyx glabrous to densely hairy, not or weakly ribbed; lobes ±equal to unequal in size, 0.9–7.8 mm long, upper lobes variously fused, of similar width to lower lobes or up to 2× as broad; adaxial lobes deltate or narrowly triangular, apex acute to acuminate, rarely subobtuse; middle and lateral abaxial lobe narrowly triangular, apex of abaxial lobes acuminate. Standard with a claw 1.2–5.1 mm long; lamina yellow, gold–yellow, apricot, orange, burnt orange or red, rarely pink, 6.0–15.0 mm long, 5.8–15.6 mm wide, with a red line, arch or series of flecks (sometimes radiating) surrounding a basal, ±ovate, yellow to pale yellow eye, circular to reniform, non-auriculate, apex slightly emarginate. Wings held over keel, coherent for length or sometimes held apart, yellow, gold–yellow, orange to deep red or rarely pink, commonly with red at base, 5.0–14.3 mm long, 0.9–2.6 mm wide. Keel ± equal to or slightly longer or shorter than the wings, yellow, gold–yellow, orange to deep red or rarely pink, commonly with red at base, 5.0–14.0 mm long, 1.2–3.7 mm wide.

Diagnostic characters

Pultenaea can be defined by the prominent stipules that are fused behind the petiole. Fused stipules are independently found in Grievea that differs in having the upper calyx lobes falcate or rounded and fused for the full length (v. only partly fused), and a consistently short claw 2.0–2.3 mm long on the standard (v. 1.2–5.1 mm long in Pultenaea); and Loricobbia that has ovoid (v. laterally flattened) ovaries that are hairy (v. glabrous) on the inside.

Distribution

A genus of over 150 species, almost all of which are endemic to eastern Australia, with a single species with a disjunct distribution across the Nullarbor into Western Australia (Fig. 12).

Fig. 12.

SB23029_F12.gif
Etymology

Pultenaea is named for English botanist Richard Pulteney (1730–1801).

Typification

Two of Bentham’s Pultenaea sections appear to be incongruently essentially based on the same type. However, the International Code of Nomenclature requires that infrageneric names with the prefix Eu- be considered invalid names for the typical (autonym) section and sections including the type species of a genus must also be considered invalid (Turland et al. 2018, Art. 21.3, 22.1, 22.2). In this case, Bentham (1864) erred in not including P. stipularis in sect. Eupultenaea.

Notes

All previously published concepts of the genus (other than the protologue) include species currently assigned to other genera, though some treatments for eastern Australia may refer to Pultenaea sens. str. by default due to the distributional scope.
