The Genus Gonatopus
 

by Wilbert Hetterscheid

Gonatopus contains 5 species only, all confined to East and Southeast Africa and Congo. With the exception of G. boivinii, all species are small geophytes, with tubers or rhizomes. Gonatopus boivinii is very common in private collections and botanical gardens and is often mistaken for an Amorphophallus. It comes in a grey and green stalked form, often thought to represent two species.

Closely related to Zamioculcas, these two genera make up the tribe Zamioculcadeae of which the closer relationships to other aroid genus-groups is unclear.
