Lvs sessile, us. rather distant, ± ascending, 6-12-(15) × 3-6-(8) mm., narrow-cuneate to cuneate-obovate or -oblong, 3-lobed at tip with narrow lateral lobes and broad, obtuse to subacute central lobe, sts incisions very shallow, glab., us. reddish when fresh, margins thickened and recurved. Fls up to 6 pairs in short or elongated raceme; pedicels up to 10 mm. long, sts > lvs. Calyx 6-12 mm. long, glab. or sparsely pubescent at very base, ± unevenly divided 1/4-⅓ way; lobes acute to obtuse, margins and midribs thickened and sts reddish. Corolla white, 15-20 mm. long, 10-15 mm. diam.; tube > calyx; lobes of lower lip c. 4-6 mm. wide, emarginate. Anthers red-brown, marginal hairs ∞, awns us. unequal.
