My unknown bamboo that I took a division from is now shooting. I've been told this could be Tuldoides. Culms are 2 inches in diameter. Primary branching is rather long measuring about 5 feet, with secondary branching having clusters of 8 to 9 small leaves.

This is one that I have also not had success with vegetative propagation, hence taking a division from the parent grove.

Hoping these new pics can help me ID this one.
