Nymphaea kakaduensis is a species of waterlily endemic to the Northern Territory, Australia. [1]
Nymphaea kakaduensis is a perennial aquatic plant with a globose rhizome. The petiolate, oval to oval-elliptic, 15.6-17.4 cm long, and 11.8-16.6 cm wide leaves have an entire, slightly undulate, or sinuate-crenate margin. 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. The globose, 2–4 cm wide fruit bears 1.8-2.1 mm long, 1.2-1.3 mm wide, dark brown to dark olive seeds with a longitudinal ridge. [2]
Flowering and fruiting occurs from April to June. [2]
It was first described by Carl Barre Hellquist, Andre Leu, and Michael L. Moody in 2021. [1]
