Studies on the Pollen Morphology of the Chinese Palmae

Zhang Jin-tan and Liu Bing-lun   

Abstract: This paper deals with morphology of the recent pollen grains of 26 species representing 16 genera and some fossil pollen of the Chinese Palmae. They are examined with the light microscope and scanning electron microscope. On the basis of the types of aperture and the distribution of fossil pollen and lithophyll in the strata, the trends of the evolution of the family Palmae are discussed. This paper points out that the monosulcate pollen belongs to the most predominent and more primitive aperture type in this family and that there is a trend in which the trichotomosulcate, annulocolpate, disulcate etc. are derived from the monosulcate pollen.
