Cajaninae of Australia (Leguminosae: Papilionoideae)

Abstract

An overview is given of the tribe Cajaninae in Australia. The number of species of the papilionoid tribe Cajaninae for the Flora of Australia is 34. Cajanus is represented by 17 species, most of these are endemic to Australia. Dunbaria has two species, Eriosema one and Flemingia eight, most of which are endemic apart from two widely distributed species that were introduced into Australia. Rhynchosia contributes six species, with the pantropical R. minima represented with four varieties. Several varieties distinguished by Domin have been upheld, one is relegated to synonymy.

Four new species are described: Cajanus hirtopilosus Maesen, C. geminatus Pedley ex Maesen, Rhynchosia bungarensis Maesen and R. filiformis Maesen. Typification of Dunbaria punctata is discussed and a neotype is designated.
