Remarkable and distinctive pollen characters support the separation of the tribe Zamioculcadeae as a group distinct from the aperigoniate Aroideae: Recently reported molecular data point in the same direction, and morphological and anatomical data likewise indicate a clear separation. Taken together, the evidence justifies the placement of at least the Zamioculcadeae in a new subfamily, Zamiocu1cadoideae. Zamioculcas and Gonatopus show greater pollen differences from the aperigoniate Aroideae than Stylochaeton, ,which seems to, represent an intermediate transition state. Nevertheless, Stylochaeton is closer palynologically and morphologically to the aperigoniate Aroideae.
