Vegetative characteristics
Nymphaea jacobsii subsp. toomba is a rhizomatous,[4] annual or perennial herb[1] with a globose to elongate, up to 25 cm long rhizome.[4] The suborbicular to broadly elliptic, petiolate, stipulate leaf with a finely dentate margin is 29–75 cm long, and 27–35 cm wide.[4]
Generative characteristics
The relatively smaller, blue flowers have green, 4.2–8.5 cm long, and 4.2–6.0 cm wide sepals with an obtuse apex. The 12–20 lanceolate, white and blue petals with an acute apex are 5–8.5 cm long, and 2.5–4 cm wide. The androecium consists of 150–300 yellow stamens. The gynoecium consists of 12–25 carpels. The globose, (2.5–)4–7 cm wide fruit bears large, hairy, ovoid, 2.6–5(–6) mm long, and 2–3 mm wide seeds.[4]
