Stem densely or sparsely retrorse-pubescent, sometimes glabrous at base or throughout, rarely with patent glandular hairs throughout. Basal leaves ovate-oblong to ovate-lanceolate, 1-4.5 x 0.5-2.5 cm, crenate, cordate to attenuate at base, petiole 1-5 cm. Cauline leaves ovate-rhomboid, broadly lanceolate to oblanceolate, 1-3 x 0.5-1.5 cm, crenate-dentate, cuneate to attenuate at base, shortly petioled to subsessile, c. 1 cm. Floral leaves elliptic to linear-lanceolate, 1-2 x 0.5-0.8 cm, weakly crenate or entire, subsessile to sessile, as long as or slightly longer than verticillasters above. Leaf indumentum sparsely adpressed-pubescent, sometimes glabrescent with sessile glands. Verticillasters usually remote, 1.5-4 cm distant, few ± approximate above, 4-8-flowered. Bracteoles few, setaceous, 1-2 mm. Pedicels 1-1.5 mm. Calyx sub-bilabiate, subcampanulate to campanulate, 10-11 mm, ± gibbous at base in fruit; teeth triangular-subulate to lanceolate with 0.5-2 mm hairy spinulescent tip, ½- 3/4 x calyx tube; calyx lips curved, tube densely villous to adpressed pubescent, sometimes glabrescent, with or without glandular hairs.
