Thank you very much Anurag Ji for sharing this and thans to Nidhan Sir, Santhan Ji and Garg Sir. This looks similar to my post https://groups.google.com/forum/#!msg/indiantreepix/jNlI1qRyZNw/t_0bu7B_eycJ where Neil Sir suggested the possibility of Vigna.

The stamens in Canavalia are monadelphous as per FoC. So, this seems to be a Dolichos. But D. trilobus L. is glabrous or almost so as per FoC. with white corolla.

The name D. trilobatus L. is Phaseolus trilobus Aiton, having small yellow flowers.

The name Dolichos trilobus is confusing, because there are one D. falcatus Willd. and one D. falcatus auct. non Willd.

I think this is possibly Dolichos tenuicaulis (Baker) Craib. (D. falcatus Willd.iii.1047 in FI)

Thank you

Regards

Thanks, Surajit ji.

Range of Dolichos tenuicaulis (Baker) Craib is Himalaya (E. Nepal to Bhutan), Khasia, Burma, Thailand, China (Yunnan) as per FON. Also it is Meghalaya¹, Orissa¹, Sikkim³, West Bengal¹ as per ILDIS

 

In south India, only Dolichos trilobus L. seems to be there as per Dolichos page.

 

Also Dolichos falcatus WILLD. is a synonym of Dolichos trilobus L. as per The Plant List & GRIN & ILDIS.

Thank you Garg Sir, perhaps you are correct, it is Dolichos trilobus L. as suggested by Santhan Ji, but flowers should be yellow in long axillary lax racemes as per link in efi page referring the book http://books.google.co.in/books?id=0tI7vIpJJxgC&pg=PA71&dq=Dolichos+%2B+india&hl=en&sa=X&ei=ruNmVJLwL4-UuASPyIK4Cg&ved=0CCQQ6AEwAjgo#v=onepage&q=Dolichos%20%2B%20india&f=false

Thank you

I think i was wrong suggesting D. tenuicaulis (Baker) Craib (as a probable id). FoC says it is found in the range of 2000-2300 m. and FBI entries are confusing, please check -

1. http://biodiversitylibrary.org/page/35622009#page/442/mode/1up
   
2. http://biodiversitylibrary.org/page/22595933#page/74/mode/1up
   

Moreover, entry in Flora Indica is also confusing, for Roxburgh connected D. falcatus Willd. (having blue-purple flowers) with D. trilobus Lour. the later being a Pueraria species!

Haines noted this in his BoBO. Prain didn't list it in his book, BP.

In spite of so much confusion it is probably not Canavalia ensiformis, which is a large climber, generally cultivated, having 1.5 to 2 inch wide pods.

So, what it is? FBI says D. falcatus Klein has yellow corolla, FI says blue-purple, FoC says white (of-course China var.)! Attached here relevant entries.

Based on above and the following links I agree with Santhan Ji -

1. http://plants.jstor.org/flora/fwta3325
   
2. http://actd.iict.pt/view/actd:LISC036931
   
3. http://actd.iict.pt/view/actd:LISC036930
   

Though initially I thought my species is also same as of Anurag Ji, I think my species may be some other for its so much hairy nature.

Thank you

Thank you very much sir.

[Vijayasankar]

It looks like Dolichos trilobus to me too.

Thank you Vijay Sir, may I have your view on another post, at https://groups.google.com/d/msg/indiantreepix/jNlI1qRyZNw/t_0bu7B_eycJ?

The main difference seen seems to be the pubescence [strigose] of the Hoogly plant as opposed to the glabrous nature of the Bangalore plant. Does it make it var pubescence?
