Perennial, profusely branched woody shrubs up to 1.8 m high or, if burnt regularly, forming very densely branched suffrutices up to 0.8 m high and 1.2 m in diameter; branches very robust and woody at base, bark pale greyish-brown, shallowly fissured; young stems less woody, green, slender, distinctly bifariously pubescent; hairs short, white, eglandular. Leaves (25-)29-30(-35) x (6-)8-10(-14) mm, opposite, very shortly petiolate; lamina narrowly ovate or oblong-ovate; base broadly cuneate; apex gradually tapered to acute with pungent, recurved apical hook; surfaces smooth, slightly shiny, glabrous or with a few eglandular trichomes along midrib (especially on abaxial surface), dark green above, yellowish-green below, somewhat thickly-textured, slightly stiff or leathery; margins entire, slightly revolute (markedly so at leaf bases); venation eucamptodromous, one main vein from base, 4-7 pairs of principal laterals, these ending before the margins, not very conspicuous; epidermal cells dense with cystoliths, imparting slightly rough texture to dried specimens; petiole (1.0-)1.4-1.6(-2.0) mm long, pale yellow to yellowish-green, glabrous or with scattered eglandular trichomes. Inflorescence an axillary, scorpioid cyme with (3-)4-6(-7) flowers maturing sequentially. Bracts 2 per flower, one longer than the other; (15-)20-22(-31) x (2.0-)3.5-3.7(-6.0) mm, lanceolate to narrowly elliptic, spinous, with a narrow blade, stiff, pale green with reddish-purple tip; midrib conspicuous, pale yellow-green; persistent after leaves and other floral parts fall; abortive inflorescences form in some lower leaf axils with only bracts properly formed giving spiny appearance to plants. Calyx of 4 dissimilar lobes, 2 outer, 2 inner; outer adaxial lobe (30-)34-38(-43) x (14-)18-20(-24) mm; outer abaxial lobe (26-)30-34(-40) x (17-)18-20(-25) mm; both outer lobes very broadly ovate or, rarely, elliptic; bases cordate; apex attenuate, ending in pungent, stiff spine (abaxial lobe sometimes ends in two apical teeth); outer surfaces very finely, shortly and densely pubescent near base, with or without short, stalked, glandular trichomes, upper parts glabrous; inner surfaces shortly pubescent or glandular-pubescent at base, upper parts glabrous; both surfaces very pale green, becoming brown or reddish-brown with age; texture soft and herbaceous initially, becoming chartaceous and stiff with age; margins entire or occasionally irregularly dentate with fine, short spines; venation extremely conspicuous, green when young, becoming red or purplish as flowers mature, (8-)10-11(-12) main veins from the base, these looping near the margins; reticulate pattern of secondary and tertiary venation clearly visible; inner calyx lobes (9.0-)12.3-12.7(-15.0) x (1.5-)2.1-2.7(-3.0) mm, linear or linear-lanceolate, apex finely pointed; surfaces very densely and finely glandular or glandular-pubescent, very pale green; texture soft, herbaceous initially becoming chartaceous with age; mid-vein conspicuous, projecting on outer surface, green initially becoming red or purple with age. Flowers (34-)39-40(-46) mm long, very conspicuous, scented nocturnally, colour ranging from almost pure white with faint pink markings to deep pink with magenta-pink markings on corolla lobes; corolla narrowly funelliform below, unequally 5-lobed above; tube narrowly cylindrical near base, gradually inflating as lobes are approached, very gently and convexly curved. Corolla obscurely bilabiate; upper lip of 4 sub-equal lobes, 2 adaxial lobes narrower and slightly shorter than two lateral lobes; adaxial lobes (19-)22-24(-27) x (8-)16-17(-18), lateral lobes (18-)21-25(-29) x (18-)20-23(-25) mm; all upper lobes elliptic or somewhat obovate to very broadly elliptic or obovate; apex acute, often sharply so; lower lip of 1 lobe, (18) 21-25(-29) x (18-)21-23(-25) mm, very broadly elliptic or broadly obovate; apex rounded to slightly retuse. Androecium comprising 2 fertile stamens and 3 staminodes. Stamens (34-)35-36(-40) mm long, epipetalous, exserted when mature; anthers (4.0-)4.6-5.3(-5.5) mm long, bright purple before dehiscence, black or grey after opening; dehiscence introrse, longitudinal; lobes linear, muticous, parallel; filaments white, glabrous except near base where glandular-pubescent, twisted and crossed over near base. Staminodes (5.0) 6.6-8.3(-10.0) mm long, epipetalous, adnate to corolla at same level as stamens; 2 staminodes with anther rudiments; filaments twisted but not crossed over near base, glabrous except at base where sparsely glandular-pubescent. Ovary superior, ovoid, 2-locular, glabrous; ovules 4; disc nectariferous, deeply cupular, surrounding ovary for three quarters of its length; style terete, white, glabrous, curved in young buds, straight when mature; stigma shortly bilobed. Fruit a capsule, (19-)20-22(-25) x (8.0-)8.3-9.7(-11.0) mm, estipitate, spindle-shaped to obtrulloid, flattened, green when young, black when mature, dehiscing explosively; surfaces glabrous, apex tapered but without an apical beak; placental bases inelastic. Seeds 4, discoid, (6.0-)6.9-7.3(-7.5) x (5.0-)5.3-5.7(-6.0) mm, discoid, borne on stiff retinacula; surfaces greyish-black, covered in hygroscopic hairs; hygroscopic hairs fused to form a continuous layer and kinked to form ridges running the width of the seeds.

Occurs in open, rocky areas on moderately sloping north-facing aspects. The soil at all of the localities is a very heavy, dense black clay strewn with doleritic rock. The plants grow at the interface of grassland and valley bushveld occurring in, or along the borders of, seasonal or perennial streams, drainage lines or boggy areas.
