Subshrubs, 1 m. Stems erect, stellate-puberulent, hairs to 0.1 mm. Leaves: stipules free from petiole, 1-veined, subulate, 5–6 mm, subequal to petiole; petiole 5–7 mm, 1/10–1/4 length of blade, stellate-puberulent; blade ± rhombic, 2.5–9 cm, smaller distally, 2–3(–4) times longer than wide, base usually cuneate, sometimes somewhat truncate to subcordate, margins serrate distally, entire basally, apex acute to subobtuse, surfaces stellate-puberulent or glabrescent adaxially. Inflorescences axillary solitary flowers. Pedicels slender, (1–)3–4 cm, 4–6 times length of calyx, much shorter than to ± equaling subtending leaf, at least distalmost.
