Abstract

Symplocos paniculata (Thunb.) Miq., a tree growing along the Himalayan ranges has anthers developing in the Dicotyledonous manner, the pollens are shed at two-celled stage. Triporate and tetraporate pollen develop into male gametophyte. Ovules are anatropous, unitegmic, tenuinucellate exhibiting Polygonum type of embryo sac with the usual organization. Stigma is of the Wet type. Fertilization is porogamous; endosperm is Cellular with oil filled cells. Embryo development is Solanad with a massive suspensor. Mature embryo is curved, dicotyl and is held within a thin, dry unspecialised seed coat. Symplocaceae shows a fairly uniform embryology.
