Morphological features of microsporangia and pollen grains from cultivated plants of Ginkgo biloba were examined using light and scanning microscopy. The sporophylls bear mainly two pendulous microsporangia; three or four were rarely found. The sporangia dehisce along a longitudinal slit and are characterized by reticulate primary sculpture. The basic shape of pollen grains is prolate and perprolate (rarely spheroidal) and they possess a single aperture, which extends from one extremity of the pollen grain to the other. The surface is rugulate, folded, psilate, psilate-slightly striate, regularly striate and fossulate. Perforations are present. Different types of sculpture were found on the same specimens. Our results suggest that although some cultivated plants are morphologically well characterized by habit and shape of leaves, they cannot be separated based on microsporangia and pollen grain morphology. In our investigations the microsporangia and pollen grain micromorphology of eight cultivars of Ginkgo were studied for the first time, providing some important new data.
