Caudices developed; roots short, fibrous, lignescent, non-tuberiferous. Stems branched proximally, 10–30 (–40) cm, faces subequal, flat to convex, 4-angled, internodes glabrous, nodes sparsely hirsute, hairs eglandular. Leaves: petiole 0.5–1.5 mm; blade ovate to suborbiculate, 1–1.5 cm × 3–10 mm, margins serrate, surfaces glabrous abaxially, sparsely villous adaxially. Inflorescences condensed, mostly obscured by foliaceous bracts. Flowers: hypanthium globose, much longer than the constricted neck, 5–7 mm, villous-hirsute, hairs gland-tipped; calyx lobes deltate, apices obtuse, hirsute, hairs gland-tipped; petals ascending, lavender-rose, 1–1.2 cm; anthers straight, 2 mm. Seeds 0.6 mm, surfaces with relatively short, interrupted, irregularly spaced, ± longitudinal ridges. 2n = 22.
