| 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. |
