The adaxial leaf surface is dark green, and the abaxial leaf surface is dark purple. The petiole is brownish-green, and exhibits fused stipules.[2]

The 5.5–10.5 cm wide, fragrant, cupped flowers extend above the water surface. The white, pink, brown, or green sepals are 3–6 cm long, and 1–2.6 cm wide. The 14-27 ovate–elliptic, white, more rarely blue, or pinkish petals are 2–5 cm long and 0.6–2 cm wide. The androecium consists of 80-200 yellow stamens. The gynoecium consists of 14-30 carpels.
