Inflorescence branches (3–) 4–7 (–10), touching for most of length (when flattened) and forming a head-like structure, 0.5–1.5 cm long, 3.5–5 mm wide including the spikelets and awns; bare tip 0.5–2 mm long, 6–25% of total branch length. Spikelets ±obovate, 3–5 mm long, 2–4-flowered, with 1–2 closely overlapping bisexual florets.

Basal lemma 2.7–3.5 mm long, muticous or aristulate, scaberulous along entire midnerve. Palea flaps distinctly narrower than or ±as wide as body. Anthers 0.3–0.5 mm long, yellow.
