Description:―Suffrutescent perennial herbs. Flowering stems erect-ascending, 20‒70 cm, branched, rarely simple, densely crisped white-lanate to lanate-tomentose. Cauline leaves ovate to ovate-oblong or oblong-lanceolate, 1‒3 × 0.5‒2 cm, serrate, rarely crenate-serrate at margin, truncate to cuneate at base, acute or obtuse at apex, mucronulate at tip, thinly adpressed canescent on upper surface, canescent beneath, petiole 0.8‒2 cm, the uppermost 5 mm to sessile. Floral leaves oblong-lanceolate to lanceolate, 0.8‒3 cm, as long as or longer than verticillasters, entire to faintly serrate at margin, subsessile to sessile, mucronate at tip. Verticillasters 1‒4(‒5), very remote (2‒7.5 cm distant), the 2‒3 upper ones sometimes crowded, forming an oblong head, 8‒16(‒25)-flowered. Bracteoles linear-lanceolate to lanceolate or lanceolate-subulate, 5‒12 mm, mucronate at tip. Pedicels 0.3‒1 mm. Calyx sub-bilabiate, ± tubular, 7‒17 mm, lanate-tomentose to tomentose, glandular or eglandular; teeth subequal, lanceolate or narrowly lanceolate-subulate, shorter to longer than tube, 2‒10 mm, recurved in fruit, mucronate at tip (mucro 0.7‒3 mm). Corolla white with purple to pink streaks and spots inside, 9‒14 mm, tube subexserted, annulate; limb bilabiate, sparsely glandular-hirtulous outside, upper lip 3‒4 mm, emarginate, lower lip 3‒lobed, middle lobe largest, 4.5‒7 mm.
