The genus was originally restricted to western tropical Africa (lUrobotrya sect. Urobotrya with 2 spp.). This section is characterized by much longer racemes with small, narrowly triangular bracts.
Two species from Indochina were originally described under Lepionurus. The young inflorescences are indeed very similar to those of that genus, but the structure of the flowers differs considerably (cf. ). Anatomical and palynological data support the opinion that Urobotrya and Lepionurus are closely allied mutually and to Gjellerupia.


Leaves and/or fruits of U. siamensis HIEPKO in Thailand locally used as a medicine against intestinal parasites, in large amounts a deadly poison.
