Abstract:Pollen morphology of the 2 species (Orchidantha chinensis and O. longisepala) inLowiacae from China was examined under SEM and LM. Their pollen grains are bean-shaped,bilaterally symmetric, heteropolar and inaperturate. The sculpture on the surface of middle part ofpollen grains is densely striate and that on surfaces of both ends of those is rugulate. Slight differ ences of sculpture exist between the 2 spedes. The features of pollen morphology of the 2 speciesshow that the pollen of Lowiaceae can be considered as a peculiar pollen type which is observed inthe order Zingiberales for the first time.
