POLLEN MORPHOLOGY OF CERTAIN TROPICAL PLANTS

[摘要]
The pollen morphology of 49 species belonging to 48 genera and 31
families ia recorded in this paper. Of these 24 and 19 taxa are studied
at generic and species level respectively.Six species are redescribed to
show the variations in the local pollen grains. In most of the species
studied presently the characters were similar to those recorded previously
for the respective families. The variations seen in some of the taxa with
regard to wall characters,nature of the apertures,etc. are poninted out.
The present observations ace comparatively discussed with reference to previous literature.
