Agrostis hookeriana (C. B. Clarke ex J. D. Hooker) var. longiflora Y. C. Tong ex Y. C. Yang; A. poluninii Bor var. longiflora (Y. C. Tong ex Y. C. Yang) B. S. Sun.
Perennial, rhizomatous. Culms erect from geniculate base, up to 70(–100) cm tall, 1–2.5 mm in diam., 3–7-noded. Leaf sheaths smooth; leaf blades linear, flat or rolled when dry, 10–16 cm × 2.5–4 mm, both surfaces scabrid, apex acuminate; ligule 2–4.5 mm, back scabrid, apex obtuse. Panicle open or laxly contracted, narrowly lanceolate to narrowly ovate in outline, 15–20(–25) cm; branches 2–6 per node in well-spaced whorls, ascending to laxly spreading, slender, 7–12 cm, scabrid, bare below middle. Spikelets 2.5–3.2 mm, green tinged purplish gray or purple; glumes narrowly lanceolate, subequal, keel scabrid, upper indistinctly keeled, almost smooth, acute; callus hairs ca. 0.3 mm; lemma ca. 2/3 spikelet length, awnless or with up to 1 mm awnlet from middle or above, lateral veins slightly keeled and scaberulous above middle, apex truncate; palea 0.2–0.5 mm, 0.15–0.3 lemma length. Anthers 1–1.5 mm. Fl. and fr. Jun–Aug.
* Moist grassy slopes, riversides; 2000–3600 m. Sichuan, Yunnan.
Agrostis kunmingensis closely resembles awnless forms of A. ca-nina in spikelet size and anther length, but appears to lack the spreading stolons typical of that species. It is also close to A. infirma, a predominantly SE Asian species.
