A illustrated account of the pollen grains of 32 species of genus Clematis (Dill, ex) Linn., mostly Indian, has been presented and their systematic significance evaluated. The pollen is usually 3-zono-colpate, but some have 4-zono-colpate pollen as well. In C. cadmia Buch.- Ham. Ex Hk.f. & Thom., the pollen is panporate. The pollen features in Clematis exhibit a predominantly negatively reticulate sexine pattern and are of little phylogenetic significance.

Abstract


A illustrated account of the pollen grains of 32 species of genus Clematis (Dill, ex) Linn., mostly Indian, has been presented and their systematic significance evaluated. The pollen is usually 3-zono-colpate, but some have 4-zono-colpate pollen as well. In C. cadmia Buch.- Ham. Ex Hk.f. & Thom., the pollen is panporate. The pollen features in Clematis exhibit a predominantly negatively reticulate sexine pattern and are of little phylogenetic significance.
