Fruit pod is not long enough , 

Your all ingredients are exactly similar to species found in Surat which is almost certainly Canavalia cathartica . 

I am waiting for mature dry pods so that seeds and hilum measurements can be done , then I shall post .

Thanks Rakesh ji.

I am going with the knowledge that C. gladiata is known as common canavalia, though I am not sure whether it is termed common because it is cultivated. Do please validate in due course whether this is the wild C. cathartica. The posted pictures are of plant growing in vicinity of human habitat, so I have considered it as an escape.

C. cathartica grows very commonly near human settlements on fences , thickets , bushes , walls . 

C. gladiata  pod is said to be 30 to 50 cm long . C. ensiformis is less longer but still longer than C. cathartica , but thinner . C. rosea is smallest .

Thanks Rakesh ji,

C. cathartica grows wild, and I thought is found along banks of rivers, canals and backwaters ... Herbarium JCB.

C. gladiata, mostly cultivated in India, Herbarium JCB ... not able to know the dimensions of pod from the description.

Let me relook into my sightings of Canavalia ... will post them for validations in due course.

Regards.

Thanks Garg ji.

I must correct all instances of Canavalia gladiata in my collection at flickr to Canavalia cathartica.

Will do the corrections.

All of them were found in similar habitat.

Regards.

[J.M. Garg]

I re-checked all the posts in efi on Canavalia.

I found most of them to be OK.

I think this post by Dinesh ji also appears to be closer to Canavalia gladiata (Jacq.) DC. (as per images and references herein) rather than those at Canavalia cathartica Thouars as the leaves appear to be acuminate rather than acute and pods also appears to be larger.

[Dinesh Valke]

Thanks Garg ji for re-validating this post.

I hope we get pods of all Canavalia spp. in our database for sake of comparison. They are definitely distinct.

Regards.

Dinesh
