Leguminosae, Papilionoideae, Vicieae, seed coat anatomy, papillose seed coat
A distinctive seed coat pattern, which contrasts with that of about 200 other genera of papilionoid legumes, is evident in 47 species of 4 genera of tribe Vicieae. A conspicuous papillose pattern, seen at magnifications of 50X or higher, is caused by protrusions from the tips of malpighian cells of the epidermis. The hilar rim is quite reduced, a rare feature elsewhere in the subfamily. These two characters, and the elongate hilum noted by others, strengthen the definition of this tribe.
