Pollen Morphology of some Carnivorous plants from Tripura, India

Abstract

Pollen morphological structure of two carnivorous plant family covering four species of Tripura, India namely Drosera
burmannii Vahl (Droseraceae) Utricularia bifida Linnaeus, Utricularia ceruleaea Linnaeus and Utricularia gibba Linnaeus
(Lentibulariaceae) have been studied under Scanning Electron Microscope for the first time. Pollen grains of the studied four
taxa varied widely among them and could be used for segregating both at generic as well as species level. Pollens of
Droseraceae shed in tetrahedral tetrad condition while those of Lentibulariaceae are in monad. The exine sculpture in
Droseraceae is spinulose while in Lentibulariaceae it is psilate to faintly gemmate
