This looks like a species of Mucuna. Photographs 1 & 2 [which are upside down] show fruit developing. Will send some of my photographs of Mucuna pruriens later.

This could be Phaseolus atropurpureus.

Yes, Macroptilium atropurpureum (DC.) Urb.

Thanks … & … I stand corrected.

Thanks … and … for the ID
Macroptilium atropurpureum (DC.) Urb. Syn. Phaseolus atropurpureus.
Initially when I checked some description I read that it has lobed leaflets and my plant doesn’t but on careful observation the plant shown by me also has lobed leaflet.
Macroptilium atropurpureum, commonly known as Purple Bush-Bean or Siratro, is a climber in the pea family native from Texas south to Peru and Brazil, and to the Caribbean, but widely naturalized in the tropics and subtropics.

Fabaceae plant for ID 10082012CS: This legume is commonly seen around our rice field
Habit: Wild creeper
Place: Hyderabad
Possible ID: Phaseolus ?

your plant material is my be Macroptilium lathyroides var. semierectum (L.) Urbn.

Thank you for the possible Id. When I checked the images, flowers do look alike but the habit of this plant is not similar. The plant i posted is a creeper which twines around other erect plants

It may then be Macroptilium atropurpureum…

Yes … Thanks a lot for the ID. I have been wanting an ID for these for long but never posted it. It matches perfectly with the images I browsed.
