Plants usually branched from the base, (5–)10–30(–35) cm, densely or sparsely covered with dendroid or stellate hairs (rarely with scattered papillae at margins of bracts), occasionally becoming glabrous. Leaf blades linear-oblanceolate, linear, or rarely narrowly linear (usually rather abruptly narrowed into mucronulate apex), usually plane, (1–)1.5–3.5 × (0.1–)0.2–0.3 cm. Inflorescences rather compact, dense, condensed in distal 1/2, occasionally interrupted in proximal 1/2, usually clavate or clavate-linear (rarely ± ovate). Bracts ovate, ovate-lanceolate, or narrowly ovate-lanceolate, 0.5–1.5(–2.5) × (0.3–)0.5–1 cm. Perianth segment 1. Fruits yellowish brown, light brown, or dark brown, usually with reddish brown spots and occasionally whitish warts, strongly convex abaxially, plane or slightly convex (occasionally slightly concave) adaxially, elliptic or obovate-elliptic, usually broadest beyond middle, 1.8–3(–3.2) × 1.5–2 mm, dull; wing absent or to 0.1(–0.15) mm wide, margins entire, apex triangular.
