Dwarf shrublet c. 150-300 mm tall, stems tufted from stout woody stock, spreading, well branched, twiggy in lower part especially when much dwarfed and gnarled, running up into relatively long simple flowering twigs, young parts puberulous, hairs c. 0.1-0.15 mm long, retrorse, closely leafy. Leaves opposite soon alternate upwards, fascicled, largest primary leaves 4-12 x 0.7-1 mm, linear, apex subacute, base slightly narrowed then expanded and half-clasping, margins entire, much thickened, revolute, leaving only a median groove on lower surface or almost entirely confluent, texture thick, venation invisible, glandular-punctate, often very minutely puberulous, hairs less than 0.1 mm long, scattered, or very nearly glabrous; axillary leaves similar but smaller. Inflorescence a terminal raceme c. 7-30 x 8-10 mm in flower (no fruiting ones seen), lower flowers distant, solitary or very loosely panicled. Bract adnate to pedicel and calyx tube, lowermost 3.3-5.5 x 1-1.3 mm, lanceolate, acute, base slightly pouched, hairs up to 0.15-0.3 mm long on margins, very minutely glandular all over both faces, sometimes a few acute hairs to c. 0.1 mm long on keel. Pedicel 0.1-0.25 mm long. Calyx 2.2-2.8 mm long, campanulate, basically 3-lobed, anticolateral lobes broadly deltoid, mostly longer than the tube, one or both lobes often bifid or sometimes more deeply divided, hairs up to 0.15-0.3 mm long on margins, very minutely glandular all over outside. Corolla tube 3.7-4.5 mm long (shorter in female flowers), funnel-shaped, limb 3.5-5 mm across lateral lobes, posticous lobes 1.3-2 x 0.8-1.2 mm, anticous lobe 2-3 x 1.1-1.7 mm, all lobes elliptic-oblong, white. Stamens: posticous filaments 2.6-3.2 mm long, anticous filaments 3-3.5 mm, all anthers well exerted. Stigma and style c. 5-8 mm long, style sparsely and minutely puberulous. Ovary c. 0.8 x 0.6 mm.
