Description:
Genus Description - Perennials; small straggling herbs, broad-leaved forest grasses, or rambling bamboo-like climbers. Leaves: blade lanceolate to ovate. Inflorescences paniculate, terminal and sometimes axillary, open, the loosely paired spikelets deciduous from summit of pedicels. Spikelets elliptical, ovate, or lanceolate, acute to attenuate, laterally compressed and keeled to terete; lower glume about 1/2 to nearly as long as spikelet, several-veined, usually keeled, separated from upper glume by a distinct internode; upper glume and lower floret subequal, about as long as spikelet, (3)5—7-veined; lower floret sterile or staminate, the palea well-developed; upper floret somewhat shorter than spikelet, elliptical to lanceolate or ovate, indurate, pale, glabrous or uncommonly pubescent, basal margins of lemma with minute, paired blisters or scars, or with conspicuous, paired, fleshy, lanceolate appendages, these adnate to basal margins of lemma but arising from rachilla internode between florets.
