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.

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

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.)
