This fine distinct-looking Bamboo seems to have a wide range in Africa, extending into 



both tropics. Barter says that it was the only arboreal grass he had seen (in Baikie's 



Niger Expedition), and that the stems were used to pole canoes, and the smaller ones 



as shafts for spears. This species has a very different appearance from the remainder of 



the genus ; but the structure of the spicule in all the species is very similar.
