Abstract
In Egypt, the seed and pollen grain morphology of the genus Tephrosia Pers. were studied using light and scanning electron microscopy. Qualitative and quantitative characters of seeds and pollen grains are presented. The data suggest that several seed and pollen morphological characters can distinguish the taxa of Tephrosia. Based on UPGMA clustering analysis and PCA, three main clades were recognized: Clade A comprising T. kassasii, clade B comprising T. apollinea, T. purpurea, T.
quartiniana, and T. uniflora, and clade C comprising T. nubica. The seed and pollen morphological data obtained in this study provide additional characters helping in classifying the genus. Dichotomous artificial keys based on seed and pollen data of the investigated taxa are presented.
