Annual stemless herb, up to 12 cm tall. Leaves few to many in rosettes, erect to decumbent; lamina 5-10 cm long, thin, elliptic to elliptic-lanceolate to ovate, sparsely irregularly denticulate, teeth obtuse, apices obtuse, when young thinly villose, later on glabrous or sparsely hairy, 5-7 nerved, narrowed below into short distinct petiole; petioles 2-3 cm long, at the base broadly dilated, vaginate. Scape 6-15 cm long, arched. Spikes nearly equalling the peduncle, narrow, dense above, below with lax, distant flowers. Bracts shorter than the calyx, concave, triangular ovate, apices sometimes slightly membranous. Sepals 2 mm long, slightly concave, anterior ones narrow obovate, elliptic to broad elliptic, middle ones narrow with distinct grooves. Corolla tube equal to the calyx, lobes small, elliptic to ovate, 1/2 mm to little longer, obtuse to truncate-obtuse, margins incised. Anthers little exserted. Capsule conically attenuated, nearly twice as long as the calyx. Seeds 5, 1.5 mm long, purplish brown, compressed.
