Leaves: petiole glabrous or short stipitate-glandular; blade rounded-reniform, deeply 5–7-lobed, 1–3.8 cm, base cordate, lobes rounded, margins dentate, apex obtuse, surfaces glabrous or short stipitate-glandular. Inflorescences dense, (sometimes secund). Flowers: hypanthium weakly bilaterally symmetric, free 0.8 mm, greenish or pinkish yellow, broadly campanulate, 4–5.5 mm, short stipitate-glandular proximally, medium stipitate-glandular distally; sepals erect, green-tipped, equal, 1.2–2 mm, apex rounded-ovate; petals usually spreading, white, broadly oblanceolate, (clawed), unlobed, 1.8–2.5 mm, margins entire; stamens included 1 mm; (filaments erect or incurved distally, relatively slender, longer than and not concealed by anthers); styles included 1.5 mm, 1 mm, 0.1+ mm diam. Capsules globose or ovoid, 3.5–4 mm, beaks divergent, not papillose. Seeds dark brown, fusiform, 0.6 mm. 2n = 14.
