Plants of unicaespitose habit from sympodial, pachymorph rhizomes, producing more or less open clumps of closely, but not densely, placed culms.The culms are strong, cylindrical, hollow, erect and arched above, 15-20 m tall, 4-10 cm diameter with walls 9-15 mm thick. Culm leaves are appressed, the lower are short and the higher are 30-45 cm long. Inflorescence is at first terminating leafy branches, ultimately resulting in elongate clusters of few spikelets or semi-capitate clusters of several spikelets at the nodes of leafless branches
