The species is strongly characterized by its panicled inflorescence, and 
in this suggests Adina. The vegetative characters and all the characters 
of the flowers and fruits are those of Nauclea to which genus the species 
properly belongs.

A scandent shrub quite glabrous except the inflorescence. 
Branches dark-brown to nearly black when dry, shining. Leaves 
thickly coriaceous, glabrous, somewhat shining, brown or pale-
