Characteristics

Dwarf woody shrublet up to c. lm tall, virgately well branched, old stems bare, young branches pubescent, hairs patent, up to 0.1-0.25 mm long, mostly gland-tipped, minute globular glands as well, often oozing and varnishing stem, closely leafy. Leaves opposite, soon alternate upwards, not fascicled but sometimes a few small leaves (incipient branches?) in upper axils, ascending or spreading, largest 5-22 x 0.7-1.2 mm, linear, apex acute, apiculate, base slightly narrowed, margins entire, plane, texture moderately thick, midrib shallowly channelled above, slightly raised below, glandular-punctate, often varnished, scattered hairs as well c. 0.15-0.25 mm long, either mostly gland-tipped or mostly acute. Inflorescence a moderately crowded many-flowered raceme, lower flowers often ± distant, c. 45-90 x 12-15 mm in flower (no fruiting ones seen), solitary at tips of many leafy branchlets. Bract adnate to pedicel and often to extreme base of calyx tube, lowermost 6-9 x 0.7-1 mm, linear-lanceolate, acuminate, mixture of gland-tipped and acute hairs up to 0.2-0.7 mm long on margins and back, inside minute viscous hairs plus few longer acute and glandular hairs. Pedicel 0.1-0.5 mm long. Calyx 3-3.5 mm long, campanulate, subequally 5-lobed roughly halfway to base, mixed glandular and acute hairs up to 0.6-1 mm long together with much shorter glandular ones all over outside, inside innumerable glandular hairs less than 0.1 mm long together with some acute and gland-tipped hairs up to c. 0.5 mm long. Corolla tube (4.5-)5-8 mm long, funnel-shaped, limb (4.5-)5-8 mm across lateral lobes, posticous lobes c. 2-3 x 1.1-1.3 mm, anticous lobe (2-)2.4-3.7 x 1.2-1.5 mm, all lobes oblong-elliptic, white. Stamens: posticous filaments c. 1.3-2 mm long, anthers in throat or mouth, anticous filaments c. 2-3.3 mm long, anthers well exerted. Stigma and style c. 5-9 mm long, style pubescent, hairs mixed glandular and acute. Ovary c. 1 x 0.5 mm, minutely glandular on upper half. Cocci not seen.
