Dendrolobium arbuscula (Domin) H. Ohashi, D. umbellatum (L.) Benth. and a Related New Species (Leguminosae-Papilionoideae: Desmodieae)

Abstract

Distinction of Dendrolobium arbuscula (Domin) H.Ohashi from D. umbellatum (L.) Benth. is confirmed by flower and pollen morphology. A new species, D. papuacola H.Ohashi & T.Nemoto, is described from Papua New Guinea which is closely allied to the former two species. A key to these species is provided. A revised description of D. arbuscula is presented. Pollen morphology of these three species are described.
