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 surpa.s.sing the disk-like 8--24-rayed sessile stigma, persistent and at length recurved. Fruit ovoid, naked, usually ripening above water. Aril none.--Rootstock creeping, cylindrical. Leaves with a deep sinus at the base. Flowers yellow or sometimes tinged with purple, produced all summer. (Name said to be of Arabic origin.)

ORDER 7. SARRACENIaCEae. (PITCHER-PLANTS.)

_Polyandrous and hypogynous bog-plants, with hollow pitcher-form or trumpet-shaped leaves_,--comprising one plant in the mountains of Guiana, another (Darlingtonia, _Torr._) in California, and the following genus in the Atlantic United States.

1. SARRACeNIA, Tourn. SIDE-SADDLE FLOWER.

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. Seeds anatropous, with a small embryo at the base of fleshy alb.u.men.--Perennials, yellowish-green and purplish; the hollow leaves all radical, with a wing on one side, and a rounded arching hood at the apex. Scape naked, 1-flowered; flower nodding. (Named by Tournefort in honor of _Dr. Sarrasin_ of Quebec, who first sent our Northern species, and a botanical account of it, to Europe.)

1. S. purpurea, L. (SIDE-SADDLE FLOWER. PITCHER-PLANT. HUNTSMAN'S CUP.) _Leaves pitcher-shaped_, ascending, curved, broadly winged; the hood erect, open, round heart-shaped; _flower deep purple_; the fiddle-shaped petals arched over the greenish-yellow style.--Varies rarely with greenish-yellow flowers, and without purple veins in the foliage.--Peat-bogs; common from N. Eng. to Minn., N. E. Iowa, and southward east of the Alleghanies. June.--The curious leaves are usually half filled with water and drowned insects. The inner face of the hood is clothed with stiff bristles pointing downward. Flower globose, nodding on a scape a foot high; it is difficult to fancy any resemblance between its shape and a side-saddle, but it is not very unlike a pillion.

2. S. flava, L. (TRUMPETS.) _Leaves long (1--3) and trumpet-shaped_, erect, with an open mouth, the erect hood rounded, narrow at the base; wing almost none; _flower yellow_, the petals becoming long and drooping.--Bogs, Va. and southward. April.
