Karunai Kizhangu fry/ Elephant Yam fry

This post has been overdue for a long time. That's b'coz I've tried to get some info about the vegetable I've used here. It is called ' Karunai kizhangu' in tamil language. It's a type of yam but I don't know any other details. So, please...if anybody can tell me the english name I would really appreciate it.
This yam can be used in puli kuzhambu as well as used to make dry curries. The dry versions are a excellent combination for sambar rice, rasam rice or curd rice.
Note: "Thankyou" foodies for letting me know that this vegetable is Elephant Yam. Here is a picture for people who do not know what it is.
