Annual herb, 70-100 mm high; primary stem erect, soon branching from base; branches ascending or decumbent, mostly simple, pubescent with retrose, acute hairs up to 0.3 mm long, mixed with minute, gland-tipped hairs, distantly leafy, mostly with only 1 pair above cotyledons. Leaf blade ovate, tapering below and 10-15 x 5-8 mm, obscurely dentate, both surfaces shortly pubescent with acute hairs mixed with minute, gland-tipped hairs. Flowers 4-10, at first crowded in heads but elongating into short spikes in fruit, diurnal; bracts adnate to calyx for 4-5 mm, elliptic to ovate in distal part, contracted into broad, membranous shaft, lowermost 13-14 x 2-6 mm, shortly pubescent on both surfaces, more densely on proximal half, hairs patent or ± retrorse, sometimes longer on margins and then up to 1 mm long. Calyx 7-8 mm long, lobes 2-3 mm long, densely pubescent with delicate, acute hairs up to 0.8 mm long, mixed with minute, gland-tipped hairs. Corolla tube cylindrical, 35-40 mm long, densely pubescent with delicate, acute hairs mixed with minute gland-tipped hairs up to 0.8 mm long; limb 15-18 mm diam., actinomorphic, lobes Y-shaped, 68 x 5-7 mm, minutely glandular-haired posteriorly, deep pink to magenta with deep yellow star-shaped patch around mouth, rays extending shortly up sinuses and enclosing dark red diamond-shaped blotch extending halfway or almost entirely up shaft, mouth encircled by sparse, stiff, acute hairs. Stamens usually 4 or anterior pair aborted, posterior pair included, anthers ±2 mm long, anterior pair exserted. Anthers 0.1-0.2 mm long. Ovary ±5 mm long, with small, rounded nectariferous gland, ±0.4 mm long; style 30-35 mm long; stigma included, ±4 mm long. Capsules 8-9 x 3-4 mm.
