This straggling plant was shot from near Tinuni where this was in abundance,
flowers deep purple, in dense, pendulous clusters.. fruits very densely hairy (though could not capture)..
Wanted to be sure if this is Mucuna pruriens (L.) DC. Please suggest..

Please also check with Mucuna nigricans.

Thanks … for this suggestion.. will try to explore further…

I checked my images of Mucuna pruriens and the flowers were in looser clusters than these.

Thanks … for further confirming, may I request to share your pics of M. pruriens…
Now I am inclined to place my plant as M. nigricans as suggested by …

After … shared his images, I am convinced that this plant is not Mucuna pruriens… rather this is Mucuna nigricans…

The species in consideration here is clearly M.nigricans.

Big beautiful flowers with signature shades of Mucuna, and large flower cluster. Wonderful sight …

Yes, this was seen wild.. cannot precisely say which tree or shrub was used as a support and this seems to have no particular choice..!!
