Its species have small, erect, cylindric, unbranched rhizomes lacking stolons. Both floating and submerged leaves are produced. The obovate to oval, glabrous, petiolate leaves with an entire margin have glabrous petioles with two primary air canals.

Generative characteristics

The small, 3–7.5 cm wide, white or rosy, flowers have peduncles with 4 primary air canals. The sepals are green. The 8–17 petals are white. The filaments are widest above the middle of the filament. The gynoecium consists of 5–12 carpels. The fruit bears smooth, ovoid, 2–3 mm long, and 1.5–2 mm wide seeds.
