Abstract

Ultrastructural study was carried out 2 groups of pollen with numerous, arranged and spirals on convex. Five species was studied; Desmos chinensis Lour. Fl., Desmos cochinchinensis Lour Fl. , Desmos dumonsus (Roxb.) Safford. , Desmos dunalii (Hk. F. et Th.) Safford. and Desmos dasymaschalus (Bl.) Safford. Pollen was collected from UKM Herbarium specimens and fresh specimen was collected at difference area in the Malaysia. They were acetolysis and dried by CPD method. Parameter studied via scanning electron microscope are mounted pollen, were stamen material; shape, P/E, size, surface structure and calpus ornamentation. Results obtained showed that pollen was inaperturate with needle structure and solitary globus. The morphology of pollen grains of all the species is presented and an identification key base on scanning electron microscope observations is tested.
