SB24021Taxonomy of the Nicotiana megalosiphon species complex (Solanaceae; Nicotiana section Suaveolentes): analyses of RADseq data identifies a new cryptic species

Mark W. Chase 0000-0002-9927-4938, Maarten J. M. Christenhusz 0000-0003-1398-8743, Luiz A. Cauz-Santos, Steven Dodsworth 0000-0001-6531-3540, Ruth Palsson 0000-0003-1460-8239, John G. Conran 0000-0003-2268-2703, Felipe Nollet 0000-0002-1362-685X and Rosabelle Samuel 0000-0003-0197-4854
 

The Nicotiana megalosiphon species complex includes several morphologically cryptic species. We use phylogenetic and population genetic approaches (maximum likelihood, admixture proportions, Bayesian species delimitation and coalescent methods) to assess delimitations of these species and on this basis, describe a new species, N. palssonae M.W.Chase & Christenh. A map of species distributions and key to the species of the N. megalosiphon species complex are also provided.

SB24004Standing on the shoulders of giants: molecular data confirm Kükenthal’s systematic placement of the Australian endemic Carex archeri (Cyperaceae)

Ana Morales-Alonso 0000-0003-1497-1070, Karen Wilson 0000-0001-7419-8222, Kerry A. Ford, Mónica Míguez, Pedro Jiménez-Mejías and Santiago Martín-Bravo
 

Images of inflorescence structures of a Carex archeri specimen (CHR-601143) – left to right: spike, utricle and achene.

The systematic affinities and biogeographic history of the Australian endemic Carex archeri are assessed for the first time. This species has traditionally been associated with different sections belonging to four of the six currently recognised Carex subgenera, however our robust results imply that C. archeri is the only representative of the subgenus in Australia. We discuss the biogeographic pattern and present a complete conservation assessment following IUCN categories and criteria. (Image credit: Ana Morales-Alonso.)

SB24006An annotated checklist of Syzygium subgenus Sequestratum (Myrtaceae)

Virva M. M. Lyytikäinen, Sebastian A. Hatt 0000-0003-4887-3508, Yee Wen Low 0000-0002-0939-9068, David F. R. P. Burslem and Eve J. Lucas
 

We present an annotated checklist of the 29 species comprising Syzygium subg. Sequestratum. Commonly occurring characters include glaucescence in the hypanthium, funnel-shaped flowers <10 mm long and coriaceous leaves with dark drying petioles in contrast to a paler leaf blade. This checklist provides a foundation for future taxonomic revision of this clade, from an early branching node in the tree of life of the world’s largest tropical tree genus.

SB23032Species delimitations in the Campomanesia xanthocarpa group (Myrtaceae): insights from molecular markers and taxonomy

Inclusive schematic representation of species delimitations in the genus Campomanesia Ruiz & Pavón.

Species of Campomanesia are economically important, being used for food and in forestry. Some of these are morphologically similar, raising doubts regarding identification. Seeking to solve this, we performed population genetic analyses with a complex of species: Campomanesia adamantium, C. costata, C. littoralis and C. xanthocarpa. Results indicated the re-establishment of Campomanesia rhombea and complexity of C. adamantium that should be explored based on additional tools. This study improves our understanding of the taxonomy of the genus. (Image credit: M. Ibrahim Uehbe de Oliveira.)

SB23029East rarely meets West: a revised delimitation for Pultenaea (Fabaceae: Mirbelieae) with reinstatement of Euchilus and three new genera from south-west Western Australia

The bush-pea genus (Pultenaea) is one of the larger legume genera in Australia but has been difficult to define. We present a new classification of the group, recognising five genera instead of one using a large DNA based analysis of relationships. Three genera are newly described and one genus is reinstated, and these are almost entirely restricted to south-west Western Australia, with true Pultenaea being mostly restricted to eastern Australia.

SB23028Elachanthus, Isoetopsis and Kippistia are nested in the genus Minuria (Asteraceae: Astereae)

Photographs of Minuria cunninghamii, Minuria leptophylla and Isoetopsis gramninifolia.

We conducted a phylogenetic analysis of Minuria and related genera and found that Elachanthus, Isoetopsis, and Kippistia phylogenetically nested in Minuria. Before 1980, Kippistia had long been considered part of Minuria. Morphological examination showed many similarities between Eleachanthus, Isoetopsis, and annual species of Minuria. We publish new combinations for four species, synonymising the three smaller genera. (Image credit: Alexander Schmidt-Lebuhn.)

SB23031Embracing biodiversity: multispecies population genomics of leafless Bossiaea species shows novel taxa, population dynamics and conservation strategies

This study investigates the population dynamics, diversity and taxonomy of leafless Bossiaea species, a distinctive group of Australian plants, by using whole-genome single-nucleotide polymorphism data. The findings suggest recognition of a new subspecies, Bossiaea vombata subsp. orientalis, and a change in status for B. milesiae to B. fragrans subsp. milesiae. We also highlight challenges in reproduction and gene flow among Bossiaea populations, emphasising the need for coordinated conservation efforts. (Image credit: Keith McDougall.)

Collections

Collections are a curation of articles relevant to a topical research area

The Genomics for Australian Plants Collection brings together outputs from activity across the three GAP streams: reference genomes, phylogenomics and conservation genomics. Taken together, the papers in this collection illustrate the challenges, potential future directions and unmitigated successes of this national-scale collaborative project. They underscore the value of a multi-institutional consortium approach and emphasise key facilitators such as carefully curated herbarium collections and national collaborative research infrastructure.

This Collection highlights integrative research exploring 'Diversity through time': the connection between evolutionary history and spatial distribution. This Collection was assembled to celebrate the XIX International Botanical Congress held in Shenzhen - the first IBC to be held in China. This landmark event highlights the rapid progress made in establishing the People’s Republic of China as one of the globally-leading research nations and provides a unique opportunity to explore collaborative research, involving botanists from all nations, to tackle the pressing need to manage the conservation of plant diversity.

Australian Systematic Botany is an international journal with a focus on the systematics of plants, algae and fungi. In this virtual issue, released to coincide with the Botany 2016 conference in Savannah, USA, we have selected some older and more recent significant articles in the areas of biogeography, systematics and palaeobotany, including controversial debate in these research fields.
