Help with I.D.

This one was in a large grove planted over 30 years ago. The grove is a dark emerald green with culms slightly over 2" in diameter.
The height of the grove is about 30ft. I transplanted this to my property on 4/17/12 and now culms are rising,,,the rest of the bamboo looks to be dying a slow death.
