Plants perennial, glabrous (occasionally indistinctly papillose on veins of leaf blades abaxially), with incrassate creeping rhizome. Stems erect, branched from proximal 1/2 of stem, 20–45 cm. Leaves: ocrea deciduous or partially persistent at maturity; blade oblong or elliptic, sometimes almost orbiculate, 3–7(–14) × 1.5–5(–7) cm, ca. 2(–2.5) times as long as wide, base broadly cuneate or rounded, margins entire or weakly crisped, apex obtuse or subacute. Inflorescences terminal, occupying more than proximal 1/2 of stem, narrowly paniculate. Pedicels articulated in proximal 1/2, filiform, 3–7 mm, articulation indistinct, scarcely visible. Flowers 10–20 in whorls; inner tepals ovate or oblong, 4.5 × 2.5 mm, widest at or near middle, base emarginate or cordate, margins entire or weakly serrate, apex commonly obtuse; tubercles absent. Achenes greenish brown, 2.8–4 × 1.5–2 mm.
