Herbaceous, flowering in seedling stage, then stem solitary, simple, erect, later loosely and laxly branched from the base and surviving for more than one season, main branches then becoming woody at the base but without a thick clump of vegetative buds, stems up to c. 400 mm long, ascending, loosely branched, somewhat hoary with coarse spreading white hairs, gland-tipped or not, as well as much shorter glandular hairs, leafy. Leaves spreading, mostly 20-60 x 9-30 mm, elliptic-ovate, the base sometimes petiole-like, margins obscurely and irregularly toothed or the toothing more pronounced and regular, both surfaces glandular-hairy. Flowers opening at dusk or in dull light. Spike few-to many-flowered, lax, often remarkably so. Bracts adnate to calyx for 3-5.5 mm, 14-30 x 5-15 mm, becoming smaller upwards, the lower ones in particular leaf-like and distant, elliptic or ovate, toothed and hairy as in the leaves. Calyx 8-15 mm long, lips 3-4 mm long, hairy. Corolla tube 24-50 mm long, glandular-pubescent, hairs up to 0.2-0.4 mm long, rarely acute hairs as well to 0.4 mm, limb held horizontally, regular; mouth with circlet of long unicellular hairs; lobes deeply notched, 4-10(-13) mm long, crimson and glandular-puberulous outside, either white inside or scarlet to bright orange to pale yellow in lower half, and there usually glandular-puberulous. Stamens 4, 2 anticous anthers 2 mm long, rarely reduced to 0.5-1 mm, shortly exserted, 2 posticous ones 3-3.5 mm long, included. Stigma 2.5-5 mm long, eventually exserted. Capsule c. 10-12 x 4-5 mm. Seeds not seen.
