Perennial herb with stems 0.04-0.15 m tall, erect to suberect, sometimes from decumbent and rooting base, with woody taproot, many-stemmed, unbranched below inflorescence, whitish- to greyish-pubescent except inflorescence. Stems green above, reddish below, all terete or inflorescence branches 2-lined; internodes all shorter than the crowded leaves except in inflorescence and sometimes towards base, eglandular. Leaves sessile; lamina 6-12 x 3.5-10 mm, ovate, concolorous, rather thickly chartaceous, not glaucous, shortly pubescent above, more densely and sometimes crisped-pubescent beneath, with margin recurved to revolute, apex depressed-concave and veins impressed, spreading to deflexed; apex subacute to rounded, margin entire, base broadly cuneate to cordate-amplexicaul; venation: 3-4 pairs of laterals curved-ascending from lower 0.25-0.5 of midrib, tertiary reticulation obscure; laminar glands pale, dense, subequal and occasionally a few black; intramarginal glands black, rather dense, regular. Inflorescence 3-c. 20-flowered, from 1-4 nodes, without lower flowering branches, narrowly pyramidal to subcorymbiform, all or individual parts dense; pedicels 1-1.5 mm; bracts and bracteoles oblong to triangular-lanceolate, black-glandular-ciliate, densely glandular-auriculate. Flowers c. 12-15 mm in diam.; buds ovoid, subacute. Sepals 2.64.5 x 1 mm, subequal, shortly united, narrowly oblong to broadly elliptic, rounded, with margin rather long- to short-glandular-ciliate or -subdenticulate; veins 5, unbranched?; laminar glands pale, linear to punctiform, occasionally with up to 6 black dots distally; marginal glands black, flat-topped. Petals bright yellow, veined red, 6-8 x 2.5-3 mm, c. 2.5 x sepals, oblong, rounded, apiculus absent; laminar glands pale and/or black, scattered, punctiform; marginal glands black, few sessile. Stamens c. 40, longest 5-7 mm, 0.8-0.9 x petals; anther gland black. Ovary c. 1 .5-2.5 x 0.8-1 .3 mm, narrowly ovoid- pyramidal; styles c. 3.5-6 mm, c. 2.4 x ovary, spreading-incurved. Capsule 4-5 x c. 2.5-3 mm, ovoid, equalling or exceeding sepals, enclosed when developing by petals twisting together. Seeds not seen.
