Abstract

Abstract:

The folial anatomy and pollen of one species of Aleurites and two spe-

cies of Vernicia were studied. The former genus is characterized by the presence of ech-

inolophate sculpture of pollen and a single outer stomatal ledge, curved cuticular ridges

of peristomatal rim as well as large nodular ornamentation on the surface of epider-

mis beneath which there is no hypodermis. The latter one is characterized by the verru-

ca-murate sculpture of pollen and the cuticular striate ornamentation on leaf surface of

epidermis beneath which there is one layer of hypodermis, although they both have pa-

racytic stomata and the Crotonic type of pollen. The genus Vernicia has not been accep-

ted for a long time, but these micromorphological characters show as additional eviden-

ce that recent separation of the two genera by Airy Shaw (1966)^[6] is reasonable.

Both genera possess very similar xeromorphic feature designated here as orbicular

lustrous spot.

Key words: Vernicia, Aleurites, Leaf anatomy, Pollen
