Cymbidium species- Andaman Island

D Help 2:
Requesting ID help.
Location : Kolkata.
Plant brought from Andaman Island. No bloom since October 2011.

Looks like Cymbidium to me. Need flowers to clarify and also need to check the length and width of the leaf. If I had to guess, may be Cymbidium aloifolium or C. bicolor.

If I have to guess, this should be Cymbidium bicolor.
