Stoloniferous perennial herb, stems 1 or 2 from the crown, simple below, sometimes branching above into a compound inflorescence, up to c. 1.3 m tall, 2-4 mm diam., erect, glabrous becoming glandular-puberulous on the inflorescence. Leaves crowded, mostly 18-53 x 6-15 mm, largest in the centre of the stem, lanceolate, apex acute, apiculate, base cordate, margins sharply serrate, glabrous, thick-textured, sessile. Flowers many in terminal racemes, sometimes compounded into panicles; bracts up to 2.5 x 1.25 mm, ovate, shortly acuminate; pedicels mostly 7-15 mm long, filiform, sharply ascending, glandular-puberulous mainly near the tip, the hairs scarcely 0.25 mm long. Calyx segments lanceolate, two anticous ones up to 2 x 1.25 mm, three posticous ones slightly smaller, glandular-puberulous. Corolla tube c. 2-2.5 mm long, base not invaginated, but pouched laterally above the entrance to the spurs, these c. 1.5 mm long, directed inwards towards each other, tips lacking dark sessile glands within; limb c. 7-12 x 8-15 mm, anticous lobe suborbicular, c. 3-5 x 6-10 mm, two lateral lobes ovate to suborbicular, c. 3-4 x 3.5-5 mm, two posticous lobes c. 2-4 x 2-2.5 mm, oblong to suborbicular, all pale pink, glabrous except for a few gland-tipped hairs outside, palate elevated into a transverse oblong pouch c. 2-2.5 mm deep at the margins, slightly depressed in the centre, closing the mouth of the tube, (the two inner angles of the pouch form the two spurs), “windows” two, one in the roof, one in the floor of the corolla tube, the upper (posticous) one concave, c. 0.5-1 mm deep, the lower one shallower. Stamens curved erect, hidden in the upper window; filaments of the anticous pair c. 2.5 mm long, glandular-pubescent above; anthers 0.75 mm long; filaments of the posticous pair c. 2 mm long, directed forward, the tips sharply curved erect, glandular-pubescent; anthers 0.5 mm long; pollen grey-green. Ovary c. 1.25 x 1 mm, deltoid in outline, ovules many in each loculus; style c. 1 mm long, stigma capitate, lying between the anthers. Capsule c. 3-7 x 3-4 mm, ovoid; seeds 1.75 mm long, curved, narrowly winged, ridged.
