I have a similar miniature bamboo called "Chopsticks" that came from a private gardener's sale. They couldn't tell me anything about it only that the grower used to travel all over the world collecting plant specimens. It is said to grow only about 18-24" tall. Unfortunately it is not doing as well as it could. I think a little more TLC on my part next season should help that. I have it in a pot so I can protect it in the winter.
