Characteristics

Rhizomatous perennial herb, stems several from the crown, tufted, simple, or sparingly branched, up to 500 mm long, c. 2 mm diam., glandular-pilose, the hairs patent. Leaves often sharply ascending, mostly 10-15 x 4-8 mm, (ratio c. 2:1), diminishing in size upwards, ovate-lanceolate, apex subacute, base subcordate, margins serrate particularly in lower half, both surfaces glandular-pilose; petioles 1-2 mm long, uppermost leaves almost sessile. Flowers many in crowded terminal racemes or panicles; bracts up to 5 x 4 mm, lanceolate, acute; pedicels c. 10-15 mm long, ascending at an angle of c. 45°, nearly glabrous to sparsely glandular-pilose, hairs c. 0.25-0.5 mm long. Calyx segments lanceolate, two anticous ones c. 2-2.5 x 1-1.25 mm, three posticous ones slightly smaller, all green, glabrous to glandular-pilose only in lower half. Corolla tube 2.5-3 mm long, invaginated, two lateral spurs c. 4 mm long, strongly curved forward, tips with dark globular sessile glands within, limb c. 15-20 x 12-15 mm, anticous lobe subrotund, c. 8-9 x 8-11 mm, two lateral lobes oblong-ovate, c. 3-4 x 5 mm, two posticous lobes oblong-ovate, c. 2.5-3 x 3-4 mm, all lobes rose-pink, thinly glandular-pilose outside, without dark sessile glands on upper surfaces of lobes; palate slightly raised with two channels running back down the floor of the corolla tube in which the filaments lie; “window” deeply concave, drawn out into a short cone c. 1-2 mm deep, yellow and maroon. Stamens projecting forward from the base of the boss produced by the invaginated corolla tube; filaments c. 2.75 mm long, shaggy with long delicate gland-tipped hairs; anthers c. 0.75 mm long, cohering strongly, pollen yellow. Ovary c. 1.25 x 1 mm, deltoid in outline, ovules many in each loculus; style 2.25 mm long, stigma capitate, emerging from the centre of the anthers. Capsule c. 5-8 x 3-4 mm, lanceolate in outline; seeds c. 1.25 mm long, narrowly winged, ribbed.
