Abstract
Present study aims to compare some selected members of Apocynaceae and Asclepiadaceae by giving special emphasis on their pollen morphology. The different taxa under investigation were Catharanthus roseus L., Tabernaemontana divaricata L., Nerium oleander L., Allamanda cathartica L., Cryptostegia grandiflora R.Br., Calotropis gigantea R.Br. and Marsdenia volubilis T. Pollen morphological analysis was done using Scanning electron micrographs. Although these families show some similarities, they differ in many features such as phyllotaxy, inflorescence type, presence or absence staminal corona, presence or absence of gynostegium, adhition of stamen to stigma, pollinial formation and nature of pollen grain-monad in Apocynaceae and tetrad in Asclepiadaceae.
