SUBORDER III. Nymphæaceæ proper. Sepals 4--6, and petals numerous in many rows, persistent or decaying away, either hypogynous or variously adnate to the surface of the compound 8--30-celled ovary, which is formed by the union of as many carpels; the numerous ovules inserted over the whole inner face of the cells, except at the ventral suture. Stigmas radiate as in Poppy. Fruit baccate, with a firm rind. Petioles and peduncles from a thick rootstock. 4. Nymphæa. Petals adnate to the ovary, large; the stamens on its summit. 5. Nuphar. Petals (very small and stamen-like) and stamens inserted under the ovary. 1. CABÓMBA, Aublet. Sepals 3. Petals 3, oval, bi-auriculate above the very short claw. Stamens 3--6; anthers short, extrorse. Pistils 2--4, with small terminal stigmas. Seeds 3, pendulous.--Slender, mainly submersed, with opposite or verticillate capillary-dissected leaves, a few floating, alternate and centrally peltate. Flowers single on long axillary peduncles. (Probably an aboriginal name.) 1. C. Caroliniàna, Gray. Floating leaves linear-oblong or -obovate, often with a basal notch; flowers 6--8´´ broad, white with yellow spots at base; stamens 6.--Ponds, S. Ill. (May--Sept., _Schneck_) to Fla. and Tex. 2. BRASÈNIA, Schreber. WATER-SHIELD. Sepals 3 or 4. Petals 3 or 4, linear, sessile. Stamens 12--18; filaments filiform; anthers innate. Pistils 4--18, forming little club-shaped indehiscent pods; stigmas linear. Seeds 1--2, pendulous on the dorsal suture!--Rootstock creeping. Leaves alternate, long-petioled, centrally peltate, oval, floating. Flowers axillary, small, dull-purple. (Name of uncertain origin.) 1. B. peltàta, Pursh. Leaves entire, 1--4´ across.--Ponds and slow streams. June--Aug. (Asia, Africa and Australia.) 3. NELÚMBO, Tourn. SACRED BEAN. The only genus of the suborder. (_Nelumbo_ is the Ceylonese name of the East Indian species, the pink-flowered N. speciosum.) 1. N. lùtea, Pers. (YELLOW NELUMBO, or WATER CHINQUAPIN.) Leaves usually raised high out of the water, circular, with the centre depressed or cupped, 1--2° in diameter; flower pale yellow, 5--10´ broad; anthers tipped with a slender hooked appendage. (Nelumbium luteum, _Willd._)--S. Conn. (probably of Indian introduction) to Lake Ontario, Mich., Minn., E. Neb., and southward; rare in the Middle States.--Tubers farinaceous and edible. Seeds also eatable. Embryo like that of Nymphæa on a large scale; cotyledons thick and fleshy, enclosing a plumule of 1 or 2 well-formed young leaves, enclosed in a delicate stipule-like sheath. 4. NYMPHÆ̀A, Tourn. WATER-NYMPH. WATER-LILY.
