Glumes ±equal to unequal, 4–9 mm long, acuminate to acute, 5–13-nerved, pubescent (with long simple, and short glandular, hairs). Basal floret: lemma body 2–3 (–4.2) mm long, as long as wide, cartilaginous to indurated, not ridged at base of lobes, with margins hyaline to membranous and glabrous to sparsely ciliate, 9-nerved with obscure or slightly prominent nerves, with erect hairs arising in lower half and much exceeding lobe bases; lemma lobes 9, longer than body, with midlobe (2–) 4–7 (–11.6) mm long; palea shorter than or as long as body, membranous, with keels ciliolate in the upper 1/2–2/3 with hairs sometimes longer towards base, with body pubescent in lower 1/3–1/2 and glabrous above or sometimes entirely glabrous, with flaps sparsely hairy.
