The species is reported from Thailand, Cambodia, Lao PR, Viet Nam, the Philippines, India and Pakistan. It is also noted from Sri Lanka (Tomooka et al. 2002).

The forest habitat of this species suffers from the general threats of loss and degradation as a result of expanding human populations, particularly conversion for agricultural purposes.
This creeping herb forms a component of the ground flora of monsoon forest. It can root from stem nodes (Tomooka et al. 2002). This species is considered to be a crop wild relative of green gram (Vigna radiata) and black gram (Vigna mungo) (Department of Agriculture, Sri lanka 2006). It is also found mountain grassland.
The seeds are used as a food in the same way as Green Gram (Vigna radiata (L.) Wilczek). The whole plant is used as fodder and is excellent for soil conservation (Jansen 1989).

I could not locate the fruits for this species but I tried to identify based on other characters. Could this possibly be Vigna dalzelliana (Kuntze) Verdc.?


Vigna dalzeliiana


did you run into any pods? i.e. later seeds. what do they look like?


Thank you very much …

And …, no I did not. I looked for it extensively in the area but all the plants were only just beginning to bloom.
