Dalrymple Vigna
Vigna luteola is a hairy, short-lived perennial vine that occurs in moist soil and grows in either a spreading or climbing fashion. Producing stems up to 6 metres long. The stems trail over the ground or twine into the surrounding vegetation. The stems root readily where they touch the ground. Taproot present.
Distributed widely across tropical and subtropical countries around the world. Often introduced as a crop for stock or pasture improvement
Vigna luteola can be found in tropical areas on many continents.It grows in swampy grasslands, on sandy lake shores, on stream sides, in wet pastures, in swamps, and in swamp forests. It prefers moist to wet clay soils, and will tolerate a wide range of salinities, from 0-10 ppt.
Twining, climbing herbaceous vine
This plant may become weedy or invasive in some regions or habitats and may displace desirable vegetation if not properly managed.
Its leaves are trifoliate, meaning they are a compound leaf of three leaflets. The leaflets are oval shaped and become acute at their apex. The leaflets are 2.5–10 cm long, and 1.5–5 cm wide.
It has numerous yellow flowers that are 1.8–2.2 cm long and are made of one large standard petal, two lateral wing petals, and two lower keel petals. This creates bilateral symmetry in the flower. It has thin, pubescent pods that are up to 4 to 8 cm long and 5–6 mm wide . The pods are range from green to brown or black as they ripen, are straight or slightly curved, plump, but constricted between the 4 to 9 seeds produced. The pod twists spirally when the seeds are dispersed.
