Cone of fruit 3' long.

ORDER 3. ANONACEAE. (CUSTARD-APPLE FAMILY.)

_Trees or shrubs, with naked buds and no stipules, a calyx of 3 sepals, and a corolla of 6 petals in two rows, valvate in the bud, hypogynous, polyandrous._--Petals thickish. Anthers adnate, opening outward; filaments very short. Pistils several or many, separate or cohering in a mass, fleshy or pulpy in fruit. Seeds anatropous, large, with a crustaceous seed-coat, and a minute embryo at the base of the _ruminated_ albumen.--Leaves alternate, entire, feather-veined. Flowers axillary, solitary.--A tropical family, excepting the following genus:--

1. ASIMINA, Adans. NORTH AMERICAN PAPAW.

Petals 6, increasing after the bud opens; the outer set larger than the inner. Stamens numerous in a globular mass. Pistils few, ripening 1--4 large and oblong pulpy several-seeded fruits. Seeds horizontal, flat, enclosed in a fleshy aril.--Shrubs or small trees with unpleasant odor when bruised, the lurid flowers solitary from the axils of last year's leaves. (Name from _Asiminier_, of the French colonists, from the Indian name _assimin_.)

Pistils 2--4 in the fertile flowers, raised on a short common receptacle; stigma broad and flat. Drupe globular, the mark of the stigma near the base, the ovary in its growth after flowering being strongly incurved, so that the (wrinkled and grooved) laterally flattened stone takes the form of a large crescent or ring. The slender embryo therefore is horseshoe-shaped; cotyledons filiform.--Flowers white, in small and loose axillary panicles. (Name from [Greek: me/ne], _moon_, and [Greek: spe/rma], _seed_.)

1. C. thalictroides, Michx. (Also called PAPPOOSE-ROOT.) Stems 1--21/2 deg. high; leaflets obovate wedge-form, 2--3-lobed, a smaller biternate leaf often at the base of the panicle; flowers appearing while the leaf is yet small.--Deep rich woods; common westward.

May.--Flowerless stems terminated by a large round 7--9-lobed leaf, peltate in the middle like an umbrella.

ORDER 6. NYMPHAEACEAE. (WATER-LILY FAMILY.)

_Aquatic perennial herbs, with horizontal rootstocks and peltate or sometimes only cordate leaves floating or emersed; the ovules borne on the sides or back (or when solitary hanging from the summit) of the cells, not on the ventral suture; the embryo enclosed in a little bag_ at the end of the albumen next the hilum, except in Nelumbium, which has no albumen. Radicle hardly any; cotyledons thick and fleshy, enclosing a well-developed plumule.--Flowers axillary, solitary. Vernation involute. Rootstocks apparently endogenous.--The few genera differ so much in the flower and fruit that they are separated into the three following suborders.

SUBORDER I. Cabombeae. Sepals and petals each 3 or sometimes 4, hypogynous and persistent. Stamens definite (3--18). Pistils 2--18, free and distinct, coriaceous and indehiscent, 1--3-seeded on the dorsal suture.--Stems slender, leafy, coated with mucilage. Flowers small.

2. Brasenia. Stamens 12--18. Carpels 4--18. Leaves all peltate.

SUBORDER II. Nelumboneae. Sepals and petals numerous in several rows, passing gradually into each other, and with the indefinitely numerous stamens hypogynous and deciduous. Pistils several, 1-ovuled, separately immersed in the obconical receptacle, which is much enlarged and broadly top-shaped at maturity, the imbedded nut-like fruits resembling small acorns. Embryo large; no albumen.--Petioles and peduncles all from the tuberous rootstock, the centrally peltate leaves and the flowers large.

3. Nelumbo. Character of the Suborder.

SUBORDER III. Nymphaeaceae 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.

Stamens indefinite, inserted on the ovary, the outer with dilated filaments. Ovary 12--35-celled, the concave summit tipped with a globular projection at the centre, around which are the radiate stigmas; these project at the margin, and are extended into linear and incurved sterile appendages. Fruit depressed-globular, covered with the bases of the decayed petals, maturing under water. Seeds enveloped by a sac-like aril.--Flowers white, pink, yellow, or blue, very showy. (Dedicated by the Greeks to the Water-Nymphs.)

Sepals 5, 6, or sometimes more, colored, or partly green outside, roundish, concave. Petals numerous, small and thickish, stamen-like or scale-like, inserted with the very numerous short stamens on the receptacle under the ovary, not surpassing the disk-like 8--24-rayed sessile stigma, persistent and at length recurved.

Sepals 5, with 3 bractlets at the base, colored, persistent. Petals 5, oblong or obovate, incurved, deciduous. Stamens numerous, hypogynous. Ovary compound, 5-celled, globose, crowned with a short style, which is expanded at the summit into a very broad and petal-like, 5-angled, 5-rayed, umbrella-shaped body, the 5 delicate rays terminating under the angles in as many little hooked stigmas. Capsule with a granular surface, 5-celled, with many-seeded placentae in the axis, loculicidally 5-valved.
