blade ovate to elliptic, 3–13 cm × 10–50 mm (not including petiole), apex acute to acuminate, sparingly pubescent, densely so on abaxial midrib.

basal pseudopetiolate, tufted, blade narrowly oblanceolate, 1.5–5 cm × 1.5–5 mm, base narrowed into long pseudopetiole, retrorse-puberulent on both surfaces;

cauline sessile, connate at base, blade linear to linear-lanceolate or linear-oblanceolate, 1–4 cm × 1.5–4 mm, apex acute.

dichasial cymes, several- to many-flowered, open, bracteate;

unisexual, some plants having only staminate flowers, others having only pistillate flowers, 20–25 mm diam.;

calyx 8–12-veined, campanulate, narrowly so in staminate flowers, broadly in pistillate, 10–15 × to 7 mm in flower, 11 mm broad in fruit, herbaceous, margins dentate, softly pubescent, lobes 5, erect, lanceolate, 2–3 mm;

petals bright pink, clawed, claw equaling or longer than calyx, limb spreading horizontally, broadly obovate, unlobed or 2-lobed, to 12 × 12 mm, appendages 4, ca. 1 mm;

stamens and stigmas equaling petal claw;

styles 5.

stamens equaling corolla;

stigmas (4–)5, equaling corolla.

broadly ovoid to globose, equaling and often splitting calyx, opening by 5 (splitting into 10) revolute teeth;

carpophore absent.
