2. N. pumi'la, Smith. (Fig. 871.) Least Yellow Water Lily. Calyx 

 of five pieces; stigma stellated, with a tootbed margin, and about ten 

 rays ; leaves ovate, cordate, their lobes approximate ; fruit furrowed 

 upwards.

 t. 2292. 



Similar to the last species, but much smaller in all its parts. Leaves 

 with the footstalks more angular, and concave above. Flowers paler, 

 with the calyx segments greener on the outside, and it is readily and 

 essentially distinguished by the toothed margin of the stigma and the 

 furrowed fruit. 



Habitat. Several of the small Highland Lakes of Scotland; 

 Chartners Lough, Northumberland. 



Perennial; flowering in July and August. 



Hooker, in his Flora Scot. v. 1, p. 169, has united this with N. 

 Kulmiana, an American species, which, if not the same, is certainly 

 most nearly allied to it ; and in his British Flora he remarks, " I am 

 even now far from certain that this ought not to be united with the 

 American N. Kalmiana."

GEN. CHAR. Calyx petaloid, of five coloured pieces, irregular, the 

 upper piece spurred at the base. Petals four, the whole or mostly 

 the two upper ones only with appendages at the base, and included 

 within the spur of the calyx. Name from Delphinus, or &*.$, 

 a Dolphin ; from the imaginary resemblance of the shape of the 

 flower to that fish.
