The glabrous, green, non-brittle petioles have four primary central and four secondary peripheral air canals.[3] The elliptic, suborbicular to orbicular leaf blade has a flat and entire margin.[2] The blade is 15.3–19.8 cm long and 10–17.3 cm wide.[3]

Generative characteristics

[edit]

The nocturnal flowers float on the water surface.[2] The non-brittle, brownish, glabrous peduncle has six primary central and 12 secondary peripheral air canals.[3] The ovoid, smooth, pilose seeds have trichomes arranged in continuous longitudinal lines.[2] The seeds are 1–1.2 mm long and 0.7–0.8 mm wide.[3]

Reproduction
