maybe a "bamboo" palm -- Chamaedorea erumpens
maybe
still not a bad price for 5 bucks

Not much of a picture... but the leaves do look very simular.
Take a look

HA!!! One of my 'bamboo' mysteries has been solved. I posted back in spring about this one .... I've no dig. camera so couldn't post a pic .... had 'berries' rather than grass-like seed ... and drew blanks. HA! Now I know. I have a palm not a 'boo.
Thanks for the post! Oh and I know you can't do so up yonder but this is grown outdoors here in full shade, dry conditions and is a clumper.

Forgot to add it grows to about 7 feet tall.

mistergwinge-
One of the clues that this is not bamboo is that the leaves are directly attached to the stalk; real bamboo leaves are generally at the end of branches.
