REVISION OF BRACHYSEMA (FABACEAE, MIRBELIEAE)

Brachysema is revised for the first time since Bentham's (1864) treatm ent in Flora Australiensis last century. In the meantime, B. sect. Lep tosema has been segregated as a genus, and Brachysema as circumscribed more narrowly here includes 10 species, three of which are new. A new phylogenetic analysis of the species is used as a basis for dividing the genus into two sections. Taxa described as new are Brachysema mino r, B. modestum, B. papilio and B. sect. Gastrocalyx. Cupulanthus is re duced to a taxonomic synonym of Brachysema. In addition, some names ar e reinstated to conform with the rules of nomenclature (B. celsianum), as a result of changes in genera (B. bracteolosum), and due to change in rank (B. melanopetalum).
