Rhizomes 1-2.5(-4) cm diam. Leaves mostly floating, occasionally submersed; petiole flattened. Leaf blade often abaxially purple on new leaves, adaxially green to greenish purple, broadly ovate to oblong, 5-25 × 4.5-15 cm, 1.1-1.7 times as long as wide, sinus ca. 1/2 length of midrib, lobes overlapping to divergent and forming V-shaped angle; surfaces glabrous. Flowers 3 cm or more diam.; sepals 5-6, abaxially green to yellow, adaxially often red-tinged toward base; petals broadly spatulate and thin, or notched and thickened; anthers (2-)3-6 mm, shorter than filaments. Fruit purple, dark brown, or rarely green, globose-ovoid, occasionally flask-shaped, 1.5-2.5 cm, strongly ribbed, deeply constricted below stigmatic disk, constriction 5-10 mm diam.; stigmatic disk red, 8-14 mm diam., with 8-14 shallow crenations; stigmatic rays 8-15, linear, terminating 0-1.6 mm from margin of disk. Seeds 2.5-3.5 mm.
