Bambusa sp

Family: Poaceae / Gramineae

Common Name: bamboo

Origin: endemic?

leaves are reportedly toxic to horses
we have a lot of bamboo all over the farm, mostly by the creek
I thought we had the Spiny Bamboo Bambusa blumeana, also sometimes called Bambusa spinosa , but I can’t see spines in these pictures
According to Stuartxchage, Bambusa vulgaris is smaller than Bambusa blumeana. It doesn’t have spiny branches.
It’s possible that we have both types of bamboo.
