Thilakan Sir,

My first reaction was also D. alata L. More so after visiting - 

1. http://www.eattheweeds.com/yam-a-the-alata/
   
2. http://davesgarden.com/guides/pf/showimage/38686/#b
   

But, i have D. alata which has winged stem - https://groups.google.com/forum/?hl=en&fromgroups#!topic/indiantreepix/nvs57NrcH2A. The stem of this plant is terete and striate.

Attaching "key" in Bengal Plants and a few more photographs.

Thank you,

Regards,

Friends have a nice Sunday .

 

Surajit ji I have gone through all the pics and checked the links from you.Thanks for the hard work you put in.I admit that I have n't done that much of home work before suggesting the 'Dioscorea alata' ID.Once it was commonly seen here also. So we will wait for better ID suggestions other than D.aculeata ;if there is any.

As per The Plant list Dioscorea aculeata Roxb.is a synonym of Dioscorea esculenta (Lour.) Burkill

[surajit koley]

Garg Sir,

Without inflorescence or tuber, i am afraid that the id of this plant cannot be ascertain.

However, attaching a link of a document on various Dioscorea.

Thank you for taking care.

[Saroj Kumar Kasaju]

I guess  this is Dioscorea alata L. Dave's Garden

Thank you

Saroj Kasaju

[J.M. Garg]

Thanks, Saroj ji,

I think matches as per illustration and image in Flora of China.

Sir,

Unlike the KEY in the "Bengal Plants", Dioscorea aculeata Roxb., synonym of Dioscorea esculenta (Lour.) Burkill, is a left-twining plant (ref. FoC sec. Dioscorea sect. Combilium).

Here it is right -twining, so it is D. alata, as has been identified by other members.

Thank you for taking care.

Regards

surajit.

[J.M. Garg]

Thanks a lot, Surajit ji
