Spikelets plump, usually elliptic, florets 2; lower glume adaxial, varying in length from very small and veinless to many-veined and subequaling spikelet, base sheathing, sometimes extended downward as a short stipe; upper glume and lower lemma similar, as long as spikelet, membranous or cartilaginous; upper lemma coriaceous, smooth, striate or rugose, margins inrolled, apex obtuse to acute, occasionally minutely mucronate; upper palea apex tucked within lemma. x = 7, 9.
