Description:
Perennial herbs with a few quadrangular branches from a basal rosette, hardly branched, to 80 cm tall, white-woolly with fine long and often coiled hairs; basal leaves oblong-spathulate, 5-8 x 1.5-3.5 cm, denticulate to entire, woolly-villous; cauline leaves with a petiole 0.5-2.5 cm long, with a blade elliptic to oblong-lanceolate, becoming shorter upwards.

Inflorescence a thyrse without a peduncle, with sessile cymose part-inflorescences forming dense clusters around the nodes and with a pair of bracts at first longer but shorter than subtending clusters towards the apex, with internodes slightly elongated and visible at the base; sepals connate to two-thirds their length, 10-veined, 8-10 mm long, almost regular, with pointed lobes narrower on the anterior side as compared with the posterior ones, villous outside and inside; corolla rose-pink, 2-lipped with tube about as long as the anterior lip, 12-15 mm long, villous on the outside of both lips, with the posterior lip obovate, hooded, with the anterior lip with 2 short lateral lobes and a 2-lobed central one; stamens inserted in the throat, with filaments hairy; anthers with 2 cells fertile and strongly diverging so that they are ultimately above one another in a vertical line, glabrous, more or less enclosed in the hood of the posterior lip of the corolla; ovary on a thick disk, deeply 4-lobed, with a slender style inserted near the base and curved along the posterior lip of the corolla, with a shortly 2-fid stigma.

Mericarps broadly obovoid, 2.5-3 mm long, with the 2 lateral and inner margins keeled, with the attachment scar circular and protruding, smooth to finely granulate.
