Description Rhizome rather long, with slightly dense roots. Culms 10-30 cm, trigonous, almost all clothed with leaf sheaths, clothed with brown and bladeless sheaths at base. Leaves longer than culm, blades 1.5-2 mm wide, slightly involute on margins, with transverse septate nodes between veins, slightly long sheathed. Involucral bracts leafy, lower involucral bracts longer than inflorescence, upper involucral bracts rather short and thin, shortly sheathed. Spikes 2 or 3, contiguous; terminal spike male, clavate or narrowly cylindric, 2-3.5 cm, shortly pedunculate; lateral spikes female, oblong, 0.8-1.5 × ca. 1 cm, laxly several flowered, shortly pedunculate. Female glumes pale laterally, green at middle, ovate or narrowly ovate, 3.5-4 mm, membranous, 3-veined, apex acuminate, mucronate. Utricles stramineous, obliquely patent, later nearly horizontally patent, longer than glume, narrowly elliptic or oblong, inflated trigonous, 4-5 mm, thickly leathery, glabrous, with 7 slightly concave veins, veins gradually indistinct toward apex, base abruptly contracted and broadly cuneate, apex abruptly narrowed to a slightly broad and short beak, orifice half-moon-shaped concave and sharply 2-toothed. Nutlets tightly enveloped in utricle, narrowly elliptic, trigonous, ca. 3 mm; style base not thickened, late deciduous; stigmas 3. [details]

Comparison 本种与矮生苔草C. pumila Thunb.近似,但雌花鳞片卵形或狭卵形,长3.5~4 mm;果囊狭椭圆形或长圆形,长4~5mm,具微凹陷的脉而区别于矮生苔草。[This species is similar to *C. pumila* Thunb., but it is distinguished from *C. pumila* by its female flower scales being ovate or narrowly ovate, 3.5–4 mm long, and its utricles being narrowly elliptic or oblong, 4–5 mm long, with slightly concave veins.] [details]
