This is a bit of a curiosity, it looks like there was once a form bambusoides that is now just lumped in with cylindrica. I have several plants purchased as cylindrica and a few purchased as bambusoides. They do appear to have enough differences I would try to collect it under both names.
Ingore the tag this is the standard form of cylindrical, it is not bambusoides.
