摘要/Abstract

Abstract:

The pollen grains of Cochlidiosperma (Veronica) hederifolia and C. (Veronica)

cymbalaria were examined under SEM and TEM. They differ vastly from those of all

the others in Veronica (sensu Elenevskij, 1977, 1978). The taxonomic relationship be-

tween the group and the other Veronica spp. is discussed with respect to both gross

morphology and pollen characters. Justification for the restoration of the genus as

a valid taxon is argued and, finally, a number of new combinations are proposed.

The group under consideration was sometimes treated as a separate genus but

more often given different ranks in the genus Veronica, which has been a controversial

group as to its concept and subdivision. No detail discussion has been made before on

the relationship between the group and Veronica. Main purpose of the present mork

is to examine pollen morphology and gross morphology of the group and to discuss

its relationship with Veronica.
