Sessile spikelet laterally flattened; silvery-white appressed hairs present at the base; callus short, truncate; lower glume rounded on back with or without 2 lateral keels; lower floret reduced to a hyaline lemma; upper floret fertile; fertile (upper) lemma 2-fid almost to the base, with a glabrous awn arising from low down on the back of the lemma. Pedicellate spikelet either 0 or much reduced.
