Description Rhizomes short, woody, obliquely ascending. Culms lateral, loosely tufted, 12–45 cm tall, trigonous, slender, sparsely covered with short soft hairs, base with dark brown, torn into fibrous, persistent leaf sheaths. Leaves shorter than the culms; leaf blades 3.5–12 mm wide, herbaceous, flat-spreading, both surfaces densely covered with short soft hairs. Bracts short-leaflike, or upper ones bristle-like, shorter than the spikelets, with a sheath 4–8 mm long, covered with short soft hairs. Spikelets 2–4, distant from one another; terminal spikelet male, narrowly cylindric, 1–2 cm long, about 2 mm wide, peduncle slender, with short soft hairs, up to 3.5 cm long; lateral spikelets female, cylindric, 1–2 cm long, 2–2.5 mm wide, with more than 10 flowers, peduncle covered with short soft hairs, 3–8 cm long, exserted from the bract sheaths. Male glumes broadly obovate, 2–2.5 mm long, pale yellow-brown, apex rounded, with a single pale yellow midvein on the back. Female glumes broadly obovate, 2–2.5 mm long, pale yellow, apex truncate or slightly emarginate, with three green midveins on the back. Utricles fusiform-broadly ovoid, obtusely trigonous, 3–3.5 mm long, longer than the female glumes, brownish green, membranous, with many fine veins, densely covered with short soft hairs, base cuneate and gradually narrowed, with a short stipe, apex gradually narrowed into a conical beak about 1 mm long, beak mouth with 2 small teeth. Nutlets tightly enclosed by the utricles, rhomboid-ovoid, trigonous, 2.2–2.5 mm long, yellow-brown, apex with a short beak, apical surface flat-concave, middle of the angles constricted, the central part of the facets raised, upper and lower parts sunken, base with a short stipe; base of style slightly thickened; stigmas 3.

Description Rhizome oblique, covered with fibrous, brown remnants of old scales. Culms 15-35 cm tall, obscurely trigonous, smooth, basal leaf sheaths dark brown, split into fibers. Leaves shorter than culm, blades 4-12 mm wide, flat, densely pilose throughout, margins scabrid. Involucral bracts leafy, pilose, blade much shorter than inflorescence, sheath 3-7 mm. Spikes 4-6; peduncles erect to flexuose, well exserted from involucral bract sheath; terminal spike male, ca. 10-flowered, cylindric, 1-2 × 0.2-0.25 cm, with peduncle 2-14 mm; lateral spikes female, oblong to cylindric, 12-40 × 2-4 mm, upper 2 contiguous, lower ones widely spaced. Female glumes pale yellow-green, broadly obovate, 2-2.5 mm, green costa 3-veined, apex truncate to rounded, awnless. Utricles greenish brown, ca. 1.5 × as long as glume, fusiform, ca. 3.5 mm, membranous, puberulent, several veined, base attenuate into a short stipe 0.3-0.4 mm, apex attenuate into a straight beak, orifice weakly 2-toothed. Nutlet yellow-brown, tightly enveloped, trigonous, fusiform, ca. 2.5 mm, with angles constricted at middle and faces excavated in both upper and lower parts, base with stipe ca. 1 mm, apex with short cylindric neck 0.4-0.5 mm; style base slightly thickened; stigmas 3.

Description Rhizomes short, woody, obliquely ascending. Culms lateral, loosely tufted, 12–45 cm tall, trigonous, slender, sparsely covered with short soft hairs, base with dark brown, torn into fibrous, persistent leaf sheaths. Leaves shorter than the culms; leaf blades 3.5–12 mm wide, herbaceous, flat-spreading, both surfaces densely covered with short soft hairs. Bracts short-leaflike, or upper ones bristle-like, shorter than the spikelets, with a sheath 4–8 mm long, covered with short soft hairs. Spikelets 2–4, distant from one another; terminal spikelet male, narrowly cylindric, 1–2 cm long, about 2 mm wide, peduncle slender, with short soft hairs, up to 3.5 cm long; lateral spikelets female, cylindric, 1–2 cm long, 2–2.5 mm wide, with more than 10 flowers, peduncle covered with short soft hairs, 3–8 cm long, exserted from the bract sheaths. Male glumes broadly obovate, 2–2.5 mm long, pale yellow-brown, apex rounded, with a single pale yellow midvein on the back. Female glumes broadly obovate, 2–2.5 mm long, pale yellow, apex truncate or slightly emarginate, with three green midveins on the back. Utricles fusiform-broadly ovoid, obtusely trigonous, 3–3.5 mm long, longer than the female glumes, brownish green, membranous, with many fine veins, densely covered with short soft hairs, base cuneate and gradually narrowed, with a short stipe, apex gradually narrowed into a conical beak about 1 mm long, beak mouth with 2 small teeth. Nutlets tightly enclosed by the utricles, rhomboid-ovoid, trigonous, 2.2–2.5 mm long, yellow-brown, apex with a short beak, apical surface flat-concave, middle of the angles constricted, the central part of the facets raised, upper and lower parts sunken, base with a short stipe; base of style slightly thickened; stigmas 3. [details]Description Rhizome oblique, covered with fibrous, brown remnants of old scales. Culms 15-35 cm tall, obscurely trigonous, smooth, basal leaf sheaths dark brown, split into fibers. Leaves shorter than culm, blades 4-12 mm wide, flat, densely pilose throughout, margins scabrid. Involucral bracts leafy, pilose, blade much shorter than inflorescence, sheath 3-7 mm.
