Base not known, but obviously more or less decumbent. Stems erect or ascending, 12-17 cm high, simple or branched at the very base, with subrosulate leaves, densely covered by patent hairs turning fulvous when dry in the lower part, appressed antrorse strigose with white hairs in upper part. Leaves oblong to elliptic, lanceolate-oblong or obovate-oblong, petiole 0.5-2.5 cm long, distinctly winged, with dense, long, patent hairs along the margin, blade 2-7 by 0.7-2.2 cm, rosetta leaves tapering gradually into petiole at base, the single leaf of flowering stems sessile with broadly rounded base or semi-amplexicaulous, long acuminate at apex, lateral nerves indistinct, upper side dark green with often fairly lax, appressed, in the lower half irregularly directed, in the distal part antrorse hairs, lower side pale with antrorse hairs especially dense on midrib and along margins. Cymes always paired, terminal or on lateral branches arising from near base, bractless, either naked in lowermost part or with a single flower in the axil between two cymes and with more flowers in their whole length; pedicels 0.5-3 mm long, that of axillary flower up to 5 mm, densely strigose. Calyx 2.5-3 mm in flower, up to 4.5 mm in fruit, lobes 2-2.5 by 0.8 mm in flower, 3-3.5 by up to 1.1 mm in fruit, ovate-lanceolate, acute, antrorse strigose especially at base, along midrib and margins. Corolla white, 4 mm long, tube c. 2 mm long, lobes suborbicular, broadly rounded, c. 2 mm wide, glabrous; fornices c. 0.8 mm wide, 0.3 mm long, finely papillate.
