Abstract
Stapletonia rigoense, a new bamboo species bearing very long internodes was described from Arunachal Pradesh, India. This taxon shows significant morphological differences to those earlier reported for closely related species, especially Stapletonia arunachalensis (H.B. Naithani) P. Singh, S.S. Das & P. Kumari and Stapletonia seshagirianum (R.B. Mazumdar) H.B. Naithani.
