Closely allied to N. lutea, but smaller in all its parts. Laminae 
about 6'o — 7'5cm. broad and 7 — 11 long, basal lobes not overlapping. 
Flowers about 3 — 4 cm. in diameter; June to August. Outer perianthal 
segments oval. Inner perianthal segments suborbicular. Anthers 
about twice as long as broad. Stigmas about 8 — 12. Margin of the 
stigmatic disc more or less lobed or toothed. Fruit narrowly bottle- 
shaped, about 4 , o— 4’5 cm. long and 2’o — 2^5 broad.

Perennial, glabrous aquatic herbs with floating laminae. Petioles long, springing from the 
rhizome. Laminae of the floating leaves larger than those of the submerged leaves. Sepals usually 4, 
rarely 3 (in N. odorata ), spreading, oblong, greenish on the outside, white or reddish or blue on the 
inside. Petals 00 , imbricate, spreading, gradually passing into staminodes and stamens, arising on 
the fused wall of the receptacle and ovary. Stamens acyclic, 00 , arising like the petals ; filaments 
petaloid. Ovary subinferior, subglobose. Nectary globose, in the centre of the stigma. Ovules pen-
