Yes, Art. It is Bambusa multiplex, a clumping type of bamboo. My friend in Bluffton SC has a hedge of bambusa. The long internodes(12" to 15", 2 nodes per arrow), perfectly round culm, no sulcus, thick walls and minimal nodes. I still have a piece or 2 in the basement. I may even have a bambusa arrow you or I made. I think it would be a good bamboo for split bamboo fly rods too.
