(Vigna unguiculata subsp. unguiculata)
Vigna unquiculata is a grain legume that originates in Africa. Attributes such as vine shape (climbing, prostrate, or semi-erect), seed color (shades of white, pink, brown, and black) and seed maturation time (60 to 240 days) vary with variety. Pods appear in V-shaped pairs.
'Samoeng' is a short, creeping cowpea vine that produces plump pods with black seeds, and is often intercropped with upland rice. It is a good variety as an understory for other crops as it fixes nitrogen and shades out weeds.
