Culms (1)2-4(6) m tall, (1)2-5 cm thick. Blades 50-90 cm long, 3-12 cm wide. Pistillate inflorescences spikes, 15-25(40) cm long, 2-5(10) cm thick, cylindrical, tightly and permanently enclosed in several to many leaf sheaths and a large prophyll, with 8-24 or more rows of paired spikelets on a thickened, strongly vascularized, tough rachis (cob), not disarticulating at maturity; fruitcases not developed, rachis internodes fused into the extra-vascular cylinder, glumes reduced, shallow. Caryopses 60-1000+, exposed and naked. Staminate panicles with a polystichous central axis and non-disarticulating branches; central axes usually much denser and thicker than the usually distichous lateral branches, these lacking abscission layers. 2n = 20.
