Perennial herb eventually forming a bushy shrublet, main stems c. 110-450 mm long (but will flower as a seedling only c. 50 mm tall), loosely well-branched, branches prostrate to suberect, often thin, weak and spindly, clad in delicate recurved hairs up to 0.1-0.2 mm long, many minute globular glands as well, young parts leafy. Leaves opposite becoming alternate upwards, not fascicled (occasionally 1 or 2 tiny leaves in axils), largest leaves 4-7(-15 in seedlings) x 0.8-1 mm, linear-oblong, apex subacute, base scarcely narrowed, margins entire, thickened, revolute, texture thick, venation invisible except for raised midrib at base on lower surface, glandular-punctate, either glabrous or few coarse broad-based hairs up to c. 0.2 mm long on margins, occasionally few on lower surface. Inflorescence a. crowded terminal spike c. 15-50 x 7 mm in fruit, mostly solitary, occasionally with 2-4 smaller subsidiary spikes loosely associated with it. Bract adnate to whole of calyx tube, lowermost 4-6.7 x 0.5-1 mm, oblong-lanceolate, subacute, very slightly concave at base, delicate hairs up to 0.1-0.25 mm long on margins, back either glabrous or with few coarse broad-based hairs along keel. Pedicels wanting. Calyx 2.4-3 mm long, campanulate, subequally 5-lobed (very rarely 3-lobed) more than halfway to base, lobes narrowly triangular, very acute, hairs up to c. 0.2-0.25 mm long on margins, slightly shorter all over outside, very minutely glandular as well. Corolla tube 3.8-5.5 mm long, funnel-shaped, minute globular glands often present outside and on backs of lobes, limb 3-5 mm across lateral lobes, posticous lobes 1-1.8 x 0.7-1.3 mm, anticous lobe 1.2-2.5 x 0.8-1.3 mm, all lobes oblong-elliptic, white. Stamens: posticous Filaments 0.7-1.4 mm long, anthers in throat or mouth, anticous filaments 1.1-1.8 mm long, anthers shortly exerted. Stigma and style c. 3.5-5 mm long, style pubescent. Ovary c. 0.7 x 0.4 mm. Cocci 1.8-2.5 x 1-1.2 mm, red-brown, very slightly rugulose. Flowering mainly between December and April, with a few records in October.
