Leaves chartaceous; petiole 5–10 mm, densely villous; lamina elliptic to elliptic-lanceolate, rarely oblanceolate, varying greatly in size, 4–20 by 1.5–7 cm, apex acuminate or acute, base cuneate, subentire or undulate-crenate, upper surface glabrous or nearly so (except on the impressed midrib), lower surface densely villous or hirsute; glandular dots many, black, scattered, conspicuous or sometimes obscure; lateral nerves 10–15 pairs, slender; veinlets very fine, obscure. Inflorescence umbellate, simple or compound, terminal on branches, rarely lateral on the main stem. Peduncle 0–2 cm. Pedicel 5–10 mm. Flowers pink to violet, rarely white, 5–7 mm. Calyx almost equaling the corolla, split nearly to base; lobes oblong-lanceolate, ca 2 mm wide, obtuse or acute, densely villous outside, with scattered black glandular dots. Corolla deeply lobed; lobes ovate 3.5–4 mm wide, acute, glabrous, with scattered glandular dots. Anthers lanceolate, ca 4.5 mm, punctate on back. Ovary glabrous; style ca 5 mm.
