Rhizomes 3-8 cm diam. Leaves mostly floating, occasionally emersed or submersed; petiole terete. Leaf blade abaxially and adaxially green, widely ovate, 10-40(-45) × 7-30 cm, ca. 1.2-1.5 times as long as wide, sinus 1/3-2/3 length of midrib, lobes divergent to overlapping; surfaces glabrous. Flowers 5-10 cm diam.; sepals mostly (6-)9(-12), abaxially green to adaxially yellow, sometimes red-tinged toward base; petals oblong, thick; anthers 3.5-9 mm, slightly shorter than filaments. Fruit green to yellow, cylindric to ovoid, 4-6(-9) × 3.5-6 cm, strongly ribbed, slightly constricted below stigmatic disk; stigmatic disk green, 20-35 mm diam., entire to crenate; stigmatic rays 8-26(-36), linear to lanceolate, terminating within 1(-1.5) mm from margin of disk. Seeds 3.5-5 mm. 2n = 34.
