Capsule oblong, 2-grooved, 2-celled, tipped with the 2 united styles, 2-parted (septicidal) when mature, several-seeded.--Shrubs, with simple, alternate, petioled leaves, without stipules, and small white flowers in simple racemes. (Greek name of the Willow.) 1. I. Virgínica, L. Leaves deciduous, oblong, pointed, minutely serrate; seeds oval, flattish, with a crustaceous coat.--Wet places, Penn. and N. J. to Fla., west to Mo. and La. 14. RÌBES, L. CURRANT. GOOSEBERRY. Calyx 5-lobed, often colored; the tube coherent with the ovary. Petals 5, inserted in the throat of the calyx, small. Stamens 5, alternate with the petals. Ovary 1-celled, with 2 parietal placentæ and 2 distinct or united styles. Berry crowned with the shrivelled remains of the calyx, the surface of the numerous seeds swelling into a gelatinous outer coat investing a crustaceous one. Embryo minute at the base of hard albumen.--Low, sometimes prickly shrubs, with alternate and palmately-lobed leaves, which are plaited in the bud (except in one species), often fascicled on the branches; the small flowers from the same clusters, or from separate lateral buds. (From _riebs_, a German popular name for the currant. Grossularia was the proper name to have been adopted for the genus.) § 1. GROSSULÀRIA. (GOOSEBERRY.) _Stems mostly bearing thorns at the base of the leafstalks or clusters of leaves, and often with scattered bristly prickles; berries prickly or smooth. (Our species are indiscriminately called_ WILD GOOSEBERRY; _the flowers greenish.)_ [*] _Peduncles 1--3-flowered; calyx as high as broad; leaves roundish-heart-shaped, 3--5-lobed._ [+] _Calyx-lobes decidedly shorter than the tube; berries apt to be prickly._ 1. R. Cynósbati, L. Stamens and undivided style not longer than the broadly bell-shaped calyx; berries large, armed with long prickles or rarely smooth.--Rocky woods, N. Brunswick to the mountains of N.

Spines often long, stout and red; _peduncles long and slender; flowers white_ or whitish; filaments capillary, 4--6´´ _long_, generally connivent or closely parallel, soon _conspicuously longer than the oblong-linear calyx-lobes_. (R. rotundifolium, _Man._, in part.)--Mich. to Tenn., west to Tex., Minn., and the Rocky Mts. 3. R. rotundifòlium, Michx. Spines short; _peduncles short; flowers greenish_ or the lobes dull purplish; filaments slender, 2--3´´ _long, more or less exceeding the narrowly oblong-spatulate calyx-lobes_.--W. Mass, and N.
