Sessile spikelet ± terete; callus narrowly obtuse to pungent, applied obliquely to the apex of the internode with its tip free; inferior glume coriaceous, rounded on the back and sides, becoming dark brown; superior glume nearly always awned; inferior floret reduced to a hyaline lemma; superior lemma stipitiform, bilobed, passing between the lobes into an awn with ± hirsute column.
