This cane has very small depressions above the nodes and the internodes are perfectly round with thick walls and a small center hole. We always called it switch cane(A. tecta) but it was re-designated a few years ago as it's own specie, A. appalachiana, as it grows primarily is the Southern Appalachian Mountains. One of the distinguishing features is that it is deciduous(looses it's leaves in the winter).
