Dwarf woody shrublet up to c. 500 mm tall, virgately well branched, old stems bare, young branches pubescent, hairs up to 0.15-0.3 mm long, patent, minute glands as well, sometimes oozing to produce a varnished effect, closely leafy. Leaves opposite, soon alternate upwards, not fascicled, largest 4-8 x 0.5-0.9 mm, spreading tips often upcurved, linear, apex acute, apiculate, base scarcely narrowed, margins entire, plane, texture only moderately thick, venation mostly invisible, midrib occasionally slightly raised on lower surface, glandular-punctate, sometimes varnished, otherwise mostly glabrous, occasionally a few of the uppermost leaves bract-like with long acute hairs on lower margins. Inflorescences crowded many-flowered raceme or spike c. 20-85 x 10-12 mm in flower, solitary at tips of many leafy branchlets. Bract adnate to minute pedicel and/or extreme base of calyx tube, lowermost 4.5-6 x 0.8-1 mm, linear-lanceolate, very acute, coarse hairs up to 0.5-1 mm long on lower margins (uppermost bracts may have few to many hairs on backs as well), minute globular glands on both surfaces. Pedicel 0-0.2 mm long. Calyx 2.2-3 mm long, campanulate, subequally 5-lobed roughly halfway to base, coarse spreading hairs up to 0.7-1.2 mm all over together with mostly minute glandular ones, these sometimes 0.1-0.25 mm long, inside many minute glandular hairs together with acute hairs to 0.3-0.5 mm long, sometimes few. Corolla tube 3-4.5 mm long, funnel-shaped, limb 4.5-5.5 mm across lateral lobes, posticous lobes 1.6-2.2 x 1-1.2 mm, anticous lobe 2.4-2.7 x 1-1.2 mm, all lobes elliptic-oblong, white fading to cream. Stamens: posticous filaments 1.5-2.7 mm long, anticous filaments 2.2-3.3 mm, all anthers well exerted. Stigma and style c. 4.2-5 mm long, style pubescent, hairs both acute and gland-tipped. Ovary c. 0.8 x 0.4 mm, minutely glandular particularly in upper half.
