Terminal inflorescence, in a loose simple or compound anthela, with 3–8 primary rays up to 10(12) cm, unequal, trigonous, with 3–11 spikelets arranged in a spike at the tip of the terminal rays; the axis portion bearing the spikelets generally longer than the spikelets themselves; bracts 3–6, flat, spreading, antrorsely scabrous on the margins, the lowest (7)10–25(36) × 0.2–0.5 cm, clearly exceeding the inflorescence; spikelets (4.5)5–15(18) × 1.5–2.9 mm, spreading to erect-spreading, lanceolate, acute, compressed, with 7–24 flowers; rachilla straight, with a hyaline membranous wing. Glumes 2.2–3.9 × 1–1.5(2.4) mm, distichous, loosely imbricate, ovate or elliptic, obtuse or truncate at the apex, sometimes slightly mucronulate, membranous, pale yellow to yellowish-brown, with 7 clearly visible and prominent veins.
