Dwarf woody shrublet, stems probably reaching at least 300 mm, probably prostrate or at least spreading, ± divaricately well branched, twiggy, old parts woody, bare, bark grey or blackish, young parts puberulous, hairs up to 0.1-0.15 mm long, retrorse, closely leafy. Leaves alternate, fascicled, largest primary leaves 5-15 x 0.8-1.2 mm, narrowly elliptic, apex subacute, base slightly narrowed then abruptly expanded and half clasping, margins entire, thickened, revolute, texture rather thin, midrib faintly visible on lower surface, hairs up to 0.2-0.3 mm long on margins of clasping base, elsewhere much shorter, up to 0.1 mm long, broad-based and coarse, mainly margins, very thinly scattered on both surfaces, also glandular-punctate. Inflorescence a very narrow panicle c. 30-60 x 10 mm terminating each twig, composed of crowded glomerules c. 5 x 6 mm in first flower, no fruiting ones seen. Bract adnate to roughly half calyx tube, lowermost 2.1-2.8 x 0.4-1 mm, slightly spathulate or oblong, subacute, a few hairs c. 0.1-0.3 mm long on margins at extreme base, otherwise up to 0.1-0.15 mm long scattered on both surfaces, broad-based and coarse, minute globular glands also present. Pedicel c. 0.1-0.2 mm long. Calyx 1.3-1.6 mm long, obliquely campanulate, 5-lobed roughly halfway to base, two anticous lobes deltoid, much broader than other three, hairs on margins up to 0.2-0.25 mm long, 0.1-0.15 outside together with globular glands. Corolla tube 1.8-2.7 mm long, broadly funnel-shaped, limb 3-4.2 mm across lateral lobes, posticous lobes 1-1.6 x 0.7-0.8 mm, anticous lobe c. 2 x 0.9-1.2 mm, all lobes oblong-elliptic, white or violet. Stamens: posticous filaments 1.6-2.2 mm long, anticous filaments 1.8-2.2 mm, all anthers well exerted. Stigma and style c. 2.2-3.5 mm long, style glabrous. Ovary c. 0.4 x 0.4 mm. Cocci not seen.
