TAXONOMY NYMPHAEA CANDIDA. 



173 



the ovary. Pollen granulate with smooth operculum, larger than in N. alba. Ovary 

 ovate or roundish, usually contracted and destitute of stamen insertions below the 

 stigma. Carpels 5 to 14; styles linear, flattened, breadth : length = i : 1.5 to 2.5; apex 

 rounded or somewhat acute. Stigma concave, yellow, red or violet, the rays terminat- 

 ing usually in 3 teeth (a central and two lateral) on the base of each style. Axile pro- 

 cess slender. Fruit ovoid or spherical ; in the former case, narrowed below the stigma, 

 which stands as it were on a short thick column surmounting the berry; greenish or 

 reddish; subtended by the persistent sepals; diameter 1.9 to 4.4 cm. Seed larger than 

 in N. alba, ellipsoid, brownish, 0.3 cm. long ; aril longer than the seed. 



Leaf cleft at base to the 

 petiole, sub-orbicular to oval, 10 or 

 12 to 30 cm. long and 25 cm. wide, 

 entire. Sinus, depth : length of leaf 

 = i : 2.5 ; lobes nearly equal, inner 

 margins curved, overlapping a little 

 above, and spreading out toward 

 periphery of leaf (or straight, and 

 parallel or touching) ; angles more 

 or less acute. Veins on under sur- 

 face of leaf prominent, the lowest 

 pair (i. e., those running into the 

 lobes) curved, and, if produced, 

 would cross, inclosing an oval area. 

 Petiole terete, smooth. 



Rhizome stout, 5 cm. or more 

 in diameter, horizontal, with strong 

 lateral roots, but often without side- 

 branches ; apex surrounded by peti- 

 oles, peduncles and stipules. Phyl- 

 lotaxy about 13 on 34 with very 

 short internodes ; the surface of the 

 rhizome may almost be said to con- 

 sist of large leaf-cushions.
