The morphological and anatomical characters of two wild Tephrosia species grown in Aden were investigated. The leaf; the shape, apex, margin, base, texture, size and venation of lamina were studied. The epidermal characters including the properties of epidermal cells (Shape, size & frequency), stomata properties (Type of stomata complex, size, frequency, index and ratio) stomata properties of (Adaxial & Abaxial) and type and size of trichomes and the anatomical characters (Thickness of Mesophyll and number of abaxial collenchyma layers in the midrib) and type of trichomes were determined.

The stem and petiole characters and main midrib were investigated. The macro and micromorphological characters show a high significant in taxonomic value for the separation between the two studied Tephrosia species.

They were 4 species in 1992 and in this study only 2 were found, that due to the human influence and heavily urban raise at every habitat in Aden.
