Abstract

Desmodium polyneurum S. T. Blake (Leguminosae-Papilionoideae: Desmodieae) described from Australia is regarded as a member of the genus Dendrolobium on the basis of its inflorescences having one flower per node, monadelphous stamens and reticulate tricolporate pollen grains. A revised description of the species is presented. Dendrolobium polyneurum (S. T. Blake) H. Ohashi is most similar to Dendrolobium umbellatum (L.) Benth.
