Seed, pollen morphology and numerical analysis of Tephrosia Pers. (Fabaceae) and their taxonomic significance

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