| Abstract | ||||
| A comparative study of the morphological features of mungbean and cowpea was carried out as an evidence for the assignment of mungbean to the genus Vigna. Both plants shared the following characters: Seed germination is epigeal. Plant is an annual herb. Branching starts at the second node from the base and continued upwards. Branches play a vital role in yield production. Stem is erect, ribbed cylindrical, solid and the upper internodes being longer. Leaves are pinnately compound, trifoliate, alternate and stipulate. The apical leaflet has two small stipels and each of the lateral ones has one small stipel. Leaflet blade is ovate. Terminal petiolule is longer than the lateral ones. Plants develop two basal simple and opposite prophylls. Inflorescence is an axillary raceme, bearing few number of flowers toward the peduncle apex. Flower is yellow, bisexual, zygomorphic and perigenous with a short pedicel and three small green caducous bracts at its base. The two keel petals are incurved and the two lateral wing petals have claw. Style is bent and bearded along the inner side. Plancentation is marginal. Fruit is a legume. Seed is small, globose and glabrous. These findings strengthen the concept that mungbean belongs to the genus Vigna. | ||||
