Spindly subshrub up to c. 1.2 m tall, sparingly branched, branches' up to c. 350 mm long, rodlike, sharply ascending, very finely ribbed by decurrent leaf bases, clad in recurved hairs 0.1-0.2(-0.25) mm long, very minutely glandular as well particularly on upper parts, closely leafy. Leaves opposite, soon alternate upwards, not or scarcely fascicled, ascending, upper half often spreading, largest leaves 6-15 x 0.8-1.2 mm, smaller upwards, linear-lanceolate, apex subacute, base slightly narrowed, margins entire, strongly revolute, decurrent down stem in very narrow ribs, texture thick, midrib slightly raised on lower surface, glandular-punctate, very minutely glandular (most easily seen on young leaves), few broad-based trichomes up to 0.1-0.2 mm long often present on margins and midrib on lower surface, sometimes wanting. Inflorescence a crowded terminal spike up to c. 80 mm long in fruit (but may begin fruiting when only c. 15 mm long), c. 15 mm in diam., usually solitary, occasionally with 1-3 subsidiary spikes immediately below the primary one. Bract adnate to whole of calyx tube, lowermost 5-7 x 0.7-1.1 mm, linear-lanceolate, inner face plane, backs rounded, both faces densely glandular-puberulous, hairs up to c. 0.1 mm long. Pedicel up to 0.4 mm long. Calyx 3-3.8 mm long, campanulate, subequally 5-lobed more than halfway to base, lobes narrowly triangular, very acute, densely glandular-puberulous all over outer surface, hairs up to c. 0.1-0.15 mm long, delicate acute hairs c. 0.2-0.25 mm long on margins only. Corolla tube 6.5-8 mm long, narrowly cylindric then expanded under the limb, limb 6-6.5 mm across lateral lobes, posticous lobes 2-2.5 x 1-1.4 mm, anticous lobe 3-3.5 x 1.1-1.6 mm, all lobes oblong-elliptic, white, backs of lobes and outside of corolla tube glandular-puberulous. Stamens: posticous filaments 1.5-2.2 mm long, anthers very shortly exerted; anticous filaments 2.2-3.2 mm long, anthers shortly exerted. Style and stigma c. 7-8.5 mm long, style puberulous.
