Stoloniferous perennial herb, stems many from the crown, tufted, branching, up to c. 450 mm long, c. 2 mm diam., decumbent, rooting near the base, glabrous, becoming glandular-puberulous only on the inflorescence branches. Leaves mostly 8-25 x 6-15 mm (ratio 1-1.5:1), ovate, apex subacute, base subcordate, margins serrate, glabrous; petioles 3-10 mm long. Flowers few to several in lax terminal racemes; bracts up to 7 x 4 mm, lanceolate, margins serrate, a few gland-tipped hairs often present; pedicels c. 25-50 mm long, spreading at an angle of c. 90°-45°, glandular-puberulous, hairs scarcely 0.25 mm long. Calyx segments lanceolate, reflexed, two anticous ones 3-4 x 1.5-1.75 mm, three posticous ones slightly smaller, all green, glandular-puberulous. Corolla tube c. 5-6 mm long, invaginated, two lateral spurs 5-7 mm long, curved forward, with a patch of dark globular sessile glands within at the swollen tips; limb c. 20-23 x 18-20 mm, anticous lobe c. 9-11 x 10-11 mm, two lateral lobes 5.5-7 x 5-7 mm, two posticous lobes 4-5 x 5 mm, all lobes suborbicular, rose-pink, sparsely glandular-pilose outside, palate without dark sessile gland dots, deeply channelled down the back and along the floor of the tube to accommodate the filaments, the “window” concave, c. 1.5 mm deep, yellow and maroon. Stamens projecting forward from the base of the boss produced by the invaginated corolla tube; filaments c. 4 mm long, glandular-puberulous; anthers c. 1.25 mm long, cohering strongly, pollen yellow. Ovary c. 1.5-2 x 1 mm, deltoid in outline, ovules many in each loculus; style 2.75-3 mm long; stigma capitate, lying between the anthers. Capsule (5-)9-14 x 4-5 mm, oblanceolate in outline; seeds 1.25 mm long, narrowly winged, not ridged.
