Leaves glabrous, mostly 11-32 x 5-17 mm (ratio 2-3(-5):1), deltoid or deltoid-ovate, apex acute, base almost truncate to subcordate in larger leaves, margins sharply serrate, teeth few, mainly in the lower half; petiole 1-6 mm long. Flowers few to several in a lax terminal raceme, usually simple, sometimes branched at the base; bracts up to c. 4 x 3 mm, ovate, very acute, glandular-puberulous; pedicels mostly 12-35 mm long, ascending at an angle of c. 45°, they and the inflorescence rhachis glandular-puberulous, the single stalk cell very small. Calyx segments reflexed, lanceolate, the two anticous ones c. 3-4 x 1.5-2, three posticous ones slightly smaller, all green, glandular-puberulous. Corolla tube c. 6-7 mm long, invaginated, two lateral spurs c. 9-11 mm long, directed straight down or down and slightly out and then describing a broad V, with a patch of dark sessile glands within near the tips; limb c. 25 x 22-25 mm, anticous lobe c. 11-12 x 15-16, lateral lobes c. 7-9 x 9-11 mm, posticous lobes c. 5-7 x 6-7, all subrotund, all “salmon-pink” to “scarlet”, “brick-red” or “crimson-lake”, sparsely glandular-puberulous outside, usually glabrous inside, occasionally with a patch of dark short-stalked glands centrally placed on face of the slightly raised palate, the “window” concave, yellow and maroon. Stamens projecting forward; anthers c. 1 mm long, cohering strongly. Ovary c. 2 x 1.75 mm, deltoid in outline, ovules many in each loculus; style c. 2 mm long, stigma capitate.
