Wild Vigna [Vigna minima (Roxb.) Ohwi & Ohashi]

Explanations

Taxonomy
According to Tateishi (1984), V.minima is very variable species.
The leaflets vary from linear to triangular-ovate or ovate. In extreme cases as described under Phaseolus heterohyllus, linear and ovate leaflets appear in the same individual.
Distribution
Taiwan, China, Indo-China, Malaysia, the Philippines and New Guinea (Tateishi, 1984).
Characteristics
V.minima has golden yellow flowers. Seed testa is smooth with dark gray color. Seeds are oblong, hilum is linear and rim-aril is thick. Mature pods are glabrous.
Pods 5-8.5 cm long, 9-12 seeded. Narrowly ovate stipules are small, 3-5 mm long, less than 4 mm wide. Bracteoles are triangular-ovate. Germination is hypogeal.
As genetic resources
The levels of resistance to insects and diseases have not been studied. Further research and collection efforts are necessary.
