Shrubs, 0.5–3.5 m. Stems erect, ascending, or spreading, not rooting at nodes; branchlets grayish brown to brown, rigid or flexible, glabrate, puberulent, or tomentulose, hairs straight. Leaves usually both fascicled and not fascicled on same plant, rarely none fascicled; petiole 1–3 mm; blade flat to cupped, elliptic, oblanceolate, obovate, or orbiculate, 4–22(–30) × 3–12(–22) mm, base rounded, margins thick, not revolute, entire or denticulate distal to middle, teeth 0–9, apex obtuse, rounded, truncate, or retuse, abaxial surface pale green, glabrate or glabrous, adaxial surface green, glabrous. Inflorescences axillary or terminal, 0.8–2.5 cm. Flowers: sepals, petals, and nectary white to lavender or blue. Capsules 4–6 mm wide, weakly lobed; valves smooth, horns subapical, prominent, erect, intermediate ridges absent.
