The leaves are 0.3-2.5 cm long, with the lower ones on simple hairy petioles, the upper ones on simple and glandular hairy petioles, 1.5-6 cm long, 0.8-4.5 cm wide, ovate, broadly elliptical, sparsely simple hairy on both sides or densely hairy above, grayish layered with simple hairs below, bluntly serrated along the edges, with simple cilia.

The inflorescence is one-sided, racemose, at the top of the stem.

The bracts are on 0.1-0.5 cm long petioles or sessile, 0.5-1.5 cm long, 0.3-0.8 cm wide, elliptical to lanceolate, densely short simple hairy on both sides and singly glandular.

The flower pedicel is 1.5-2.5 mm long, short simple and glandular hairy.

The calyx is 2-3.5 mm long, bilabiate, with equal lobes, the appendage larger than the upper lip, simple and glandular to densely layered with simple and singly glandular hairs.
