Abstract

The pollen morphology of 28 species belonging to three genera (Melilotus, Trifolium and Trigonella) of subfamily Papilionoideae in Egypt was studied. The size, shape, exine ornamentation and structure of the aperture allowed the recognition of three pollen types, viz. Trifolium type (subtypes 1 and 2), Trigonella type and Melilotus type (subtypes 1 and 2). This result will help establishing the taxonomic position of the species within their genera. A key to the generic types and subtypes is given.
