Biology:
The Australian species has been treated as distinct from T. triandra, which was then considered to be confined to the Old World. Clayton & Renvoize (1982), Fl. Trop. East Afr. Gramineae (3):830, and Simon (1985), Aust. Syst. Bot. Soc. Newsl. 43:15-17, are followed in combining these species.
