Description:―Suffrutescent perennial herbs without basal rosettes of leaves. Flowering stems 15‒65(‒80) cm, numerous, erect or ascending, simple or branched, densely or sparsely adpressed-pilose to glabrescent. Cauline leaves oblanceolate or lanceolate to narrowly linear-oblong, 0.8‒6 × 0.1‒1.2 cm, crenate to serrate or subentire to entire at margin, attenuate at base, sessile, acute to subobtuse at apex, densely or sparsely adpressed pilose to glabrescent. Floral leaves lanceolate, gradually becoming ovate-lanceolate above, 4‒25 mm, longer than verticillasters, uppermost as long as or shorter than verticillasters, subentire to entire at margin, acute at apex, sessile. Verticillasters 3‒10(‒15), remote below (1.5‒5 cm distant), the uppermost approximate, (2‒)4‒8(‒10)-flowered. Bracteoles few, small, setaceous, 0.5‒ 3 mm. Pedicels short, 0.5‒1.5 mm. Calyx subbilabiate, subcampanulate to tubular, 5‒10 mm, sparsely or densely adpressed pilose with few sessile glands, mouth scarsely hairy (between calyx teeth); teeth subequal, triangular-lanceolate, erect to recurved in fruit, as long as to half the length of tube, 1.8‒3.5 mm, mucronate at tip (mucro 0.3‒1.5 mm). Corolla purplish-pink or creamy-yellow to white with pink markings, 8‒16 mm, tube subexserted, annulate, limb bilabiate, adpressed pilose outside, upper lip 3‒6 mm, slightly shorter than the lower, emarginate, lower lip 3-lobed, middle lobe largest and suborbicular, 4‒8 mm. Stamens 4, slightly exserted from corolla tube (less than half-way along upper corolla lip). Nutlets obovoid, faintly trigonous, slightly winged near base, 1.6‒2.3 × 1.3‒1.8 mm, minutely reticulate, blackish-brown.
