Leaves opposite; stipules ± persistent, divided into 2 or 3 filiform segments, 0.5–3.5 mm; petiole (1–)3–6 mm; blade broadly ovate, deltate, cordate, or reniform, (0.2–)0.5–1.6 cm × 4–12 mm, base truncate to rounded, apex acute to cuspidate. Inflorescences terminal, open, 3–15-flowered cymes. Pedicels shorter to longer than subtending bracts at maturity. Flowers: sepals with 3 distinct veins arcing outward at midsection and ± confluent apically, lance-ovate to elliptic (herbaceous portion linear-lanceolate to narrowly ovate), 3–4(–5) mm, subequal, apex acute to acuminate (herbaceous portion often obtuse), not hooded, glabrous; petals 2-fid for 1/2–3/4 their length, 2.7–6 mm, subequal to sepals, lobes 1-veined, vein dichotomously branched distally, oblong, trunk entire, base abruptly tapered, apex deeply notched. Seeds dark brown to blackish, snail-shell-shaped, 0.5–0.7 mm; tubercles prominent, conic.
