Is it edible?

It is not a blackeye pea, it is not a cannellini, nor a Spanish faba (with a B not a V) or an alubia.

Sorry, I haven't figured out how to upload the picture to the message...

That looks like sword bean (Canavalia gladiata). It's found in parts of south India.

Yes, it's edible, but it seems to be more often the unripe pods that are eaten. There has been a bit of a craze for them in Japan.

Thanks a bunch Neil, I am visiting folks down in the Caribbean and they had it growing among the plantain rows as a green mulch.
Now that I had a name, I searched Go-ogle, and the gladiata is reddish and the ensiformis is white. So what I saw were Canavalia Ensiformis. Thnaks again!
