berries nearly globose, about 12 mm. in diameter, “subtransparent,” yellowish-white 
tinged with red.—Discovered along the Perdinales River and not recorded since. 
Very near to the last species, but a smaller shrub, with usually more leaflets, and 
larger berries of a different color. 
NYMPHHACER. (WATER-LILY FAMILY.) 
Aquatic perennial herbs, with horizontal rootstocks, peltate (or some- 
times cordate) leaves floating or emersed, and solitary axillary flowers. 
* Sepals and petals each 3 (rarely 4): stamens 3 or 4: pistils (2 or 3) free and dis- 
tinct: stems slender, leafy, coated with mucilage: flowers small, 
1, Cabomba. Submersed leaves capillary-multifid, 
** Sepals and petals numerous in several rows, passing gradually into each other: 
stamens indefinitely numerous: pistils separately immersed in an obconical recep- 
tacle which is much enlarged and broadly top-shaped at maturity, the imbedded 
nut-like fruits resembling small acorns, 
2. Nelumbo. Leaves centrally peltate and flowers large, 
** * Sepals 4 to 6, and petals numerous in many rows, either free from or adnate to 
the surface of the compound many-celled ovary, which contains numerous ovules 
attached over the whole inner face of the cells: fruit berry-like, with a firm rind, 
3. Castalia. The large petals adnate to the ovary, and the stamens on its summit. 
4. Nymphea. The very small and stamen-like petals and stamens inserted under 
the ovary. 
1. CABOMBA Aublet, 
Slender mainly submersed plants, with opposite or whorled capillary- 
dissected leaves, a few floatin g alternate and centrally peltate ones, and 
single small flowers on long axillary peduncles, 
1. C. Caroliniana Gray. Floating leaves linear-oblong or obovate, often with a 
basal notch: flowers 12 to 16 mm, broad, white with yellow spots at base.—Common 
in ponds and creeks, 
2. NELUMBO Tourn. (SacrEp BEAN.) 
The only genus in the suborder, and sufficiently described in the 
generic key. 
1. N. lutea Pers, Leaves usually raised high out of water, circular with the center 
depressed or eupped, 3 to6 dm. in diameter: flowers pale yellow, 12.5 to 25 em. broad. 
(Nelumbium luteum Willd.)—Along the lower Rio Grande. Called by various local 
names, such as ‘ yellow nclumbo,” “ water chinquapin,” etc., but none are as good as 
the original Ceylonese name “nelumbo.” 
3. CASTALIA Salisb. (Warrer-nymrn. WATER-LILY,) 
Flowers very showy (white, pink, yellow, or blue), sepals 4 and green 
outside, petals numerous, the innermost gradually passing into Stamens, 
the many-celled ovary concave at summit and with radiate stigmas, 
fruit depressed: globular, maturin g under water. 
1, C. ampla Salish. Leaves large, cordate with a deep narrow sinus and a little 
peltate, sinuate-dentate, usually purple beneath, and the sepals with purple lines: 
petals white or creamy-white. (Nymphaea ampla DC.)—A Mexican species, but col-
