The typically distinctive and elaborate external structures and sculpturing of pollen grains have been widely used in the taxonomy and systematics of the flowering plants.

The family Acanthaceae is a striking example, where the widely diverse external pollen grain morphology has proved useful in determining relationships between taxa.

Morphology and geographic variation of pollen grains of three genera of the Rosaceae (Dryas, Fragaria, Holodiscus) of western Canada were studied using the light microscope and scanning electron spp.

pollen is tricolporate with a weakly developed fusiform aperture in the colpus, which upon expansion of the grain becomes a large rectangular opening.

We characterized the morphology of pollen grains in all 18 species of Chrysolaena. Results show that all studied species possess pollen grains of type “C”, which is therefore characteristic of the genus. This pollen type is 3-colporate, echinolophate, oblate-spheroidal, with a total of 29 lacunae, including the polar lacuna, but lacking the.
