Leaves 7 - 15 (20) mm long and 3 - 8 mm wide, triangular ovate to lance; lower densely spaced, upper distant, glandular fibrous, rarely glabrous. Inflorescence glandular fibrous угеьшеьи, 3 - 10 cm long and 2 - 4 cm wide; the lower овдуеиs distant, the upper ones close together. Bracts 1 - 2 cm long, glandular fibrous, pale brown, triangular lance, gradually pointed, almost equal to the corolla. The flowers are fragrant. Calyx 8 - 15 mm long, glandular fibrous, about 2 times shorter than the gingival tube, composed of 2 lance ovate shares, divided to the middle into 2 unequal teeth; teeth gradually pointed, more or less keel-shaped on the back, shorter by 1, longer by 3 veins. Corolla 1.5 - 2.5 cm long, bell-shaped, short glandular fibrous, the longitudinal dorsal line evenly arched, waxy yellow on the outside with purple-red veins, red on the lips, rarely yellow, naked on the inside and dark red and shiny, below the base of the stamens narrowed and upwards dilated. Upper lip keeled, entire or shallowly 2-part, with almost rounded, slightly curved back parts; the lower one with rounded, shallowly serrated and finely ciliated lobes along the edge, the middle one larger than the lateral ones, obliquely directed downwards. Stamens caught 0.5 - 2 mm from the base of the corolla; the petioles to the base and the corolla below them covered with simple, and to the top with glandular hairs or bare. The ovary is oblong-elliptic, glabrous or at the top, as well as the column, glandular fibrous. The style is often reddish at the top. Stigma yellow, often with a red wreath at the base.
