A compact, semi-woody, perennial herb with a thin, woody rootstock, branching from the base, forming small cushions 7-14 cm in diameter. Stems mainly prostrate, glabrous, slender, somewhat quadrangular, 4-11 cm long. Leaves crowded, opposite or subopposite or in whorls of 3 or 4, secund, erect, glabrous, linear, scarcely narrowed at the base, 1.0-1.6 cm long and up to 1 mm broad, drying blackish; margin narrowly revolute, entire; median nerve prominent below, slightly impressed above. Flowers crowded towards the centre of the plant, solitary in the leaf axil; pedicels 2-3 mm long; bracteoles 2, linear, erect or subspreading, 4-5 mm long, inserted at or below the base of the calyx. Calyx funnel-shaped, equally 5-toothed, 10-nerved, 6-7 mm long at flowering stage, glabrous; tube 3-3-5 mm long; teeth ovate-triangular, acute, 3-3.5 mm long, each with a distinct median nerve. Corolla funnel-shaped, pink to rose-red, drying black, minutely and sparsely puberulous without, 1.6-2 cm long and 1.4-1.8 cm wide at the mouth; tube 1.1-1.3 cm long; limb somewhat spreading, 5-lobed; lobes subequal, broadly rounded, 5-7 mm long and 5-7 mm broad. Stamens included, didynamous; filaments slender, minutely puberulous below, the two shorter 4 mm long attached 5 mm above the base of the corolla tube, the two longer 7-8 mm long attached 2-2.5 mm above the base of the corolla tube; anthers 2-celled; cells diverging, oblong-falcate, 2 mm long, mucronulate, one cell narrower than the other Ovary ovoid, compressed, glabrous, 2 mm long, 2-celled; ovules numerous; style filiform, glabrous, 1-2 cm long, exceeding the stamens, slightly exserted; stigma somewhat thickened, minutely bifid. Capsule included in the persistent calyx, woody, compressed, widening obliquely towards the apex, obscurely bilobed, one lobe acute with often the base of the style persisting, the other lobe rounded, dehiscing along the apex. Seed numerous, oblong, 1.25 mm long; testa reticulate. From: Codd, LEW. 1964. Scrophulariaceae. Bothalia 8(2): 176-177. [https://doi.org/10.4102/abc.v40i2.210] [CC BY]
Compact, semiwoody perennial herb. Rootstock thin, woody, branching from base, forming small cushions 70-140 mm in diameter. Leaves crowded, linear, 10-16 x 1 mm, drying black. Filaments minutely pu-berulous below. Flowers pink to rose-red. From: Retief, E; Herman, PPJ. 1997. Plants of the northern provinces of South Africa: Keys and diagnostic characters.

Readily distinguished from the other species by the dwarf, compact habit and the narrow, linear, glabrous leaves. The flowers are smaller and, because of the short internodes, appear close together near the centre of the small cushions. The plants are inconspicuous and are easily overlooked except during their short flowering period in spring. From: Codd, LEW. 1964. Scrophulariaceae. Bothalia 8(2): 176-177.

Grows in sparse mountain grassland on poor, gravelly, quartzitic soil. From: Codd, LEW. 1964. Scrophulariaceae. Bothalia 8(2): 176-177. [https://doi.org/10.4102/abc.v40i2.210] [CC BY]

Known only from the top of the Steenkampsberg, on the road from Lydenburg to Draaikraal. From: Codd, LEW. 1964. Scrophulariaceae. Bothalia 8(2): 176-177. [https://doi.org/10.4102/abc.v40i2.210] [CC BY]
