Leaves opposite or alternate, often tending to be crowded at the tips of the branchlets, lanceolate to elliptic, 6-10 (-20) x 3-6 mm, tapering to a broad, flat petiole-like base, margins ciliate, the hairs extending particularly to the midvein below, often to the upper surface as well. Flowers solitary in upper leaf axils, pedicels villous, 1-20 mm long, very variable even on one plant, flowers mauve-blue. Ovary villous, hairs patent, style base broadened into a shallow cone filling the base of the calyx tube, accrescent, finally forming the domed lid of the capsule.
