Hairy perennial herb with persistent elongated slender or stout taproot.

Lamina 1.5-4-(7) × 1-1.7 cm, oblanceolate, obovate, or almost elliptic, membranous; main veins 3; base attenuate; apex obtuse to acute. Scape 2-7-(14) cm long, with antrorse hairs. Spike 0.8-5.5 cm long, narrow-cylindric, dense. Bracts to almost = calyx, lanceolate-ovate or ovate; margins scarious; keel acute, ciliate, purplish. Sepals subequal, 1.7-2.3 mm long, broad-ovate, scarious apart from the herbaceous, purplish and sometimes slightly hairy keel. Corolla tube = calyx; lobes 1-1.5 mm diam., broad-ovate or suborbicular, ± mucronulate, reflexing. Stamens glabrous, ± exserted. Style with somewhat curly hairs, well exserted. Capsule 2.5-3 mm long, subglobose to broad-ovoid, mucronate, usually 5-seeded. Seeds mostly 1.2-2 mm long, oblong-elliptic to obovoid, brown, compressed; 1 seed smaller (c. 1 mm long) and more irregular, separated from the others by a horizontal placental outgrowth towards apex.
