Part 61 (1/2)

1. P. parviflra, DC. _Petals sessile_, little longer than the calyx (3” long); _sterile filaments about 7 in each set, slender; leaves ovate or oblong_, tapering at base.--Sandy banks, Lab. to Mich., N. Minn., and westward.

2. P. pal.u.s.tris, L. Scapes 3--10' high; leaves heart-shaped; flower nearly 1' broad; _petals sessile_, rather longer than the calyx, few-veined; _sterile filaments 9--15 in each set, slender_.--Same range as the last. (Eu.)

3. P. Caroliniana, Michx. Scapes 9'--2 high; flower 1--1' broad; _petals sessile_, more than twice as long as the calyx, many-veined; _sterile filaments 3 in each set, stout, distinct almost to the base_; leaves thickish, ovate or rounded, often heart shaped, usually but one low down on the scape and clasping.--Wet banks, N. Brunswick to Fla., west to Minn., Iowa, and La.

4. P. asariflia, Vent. _Petals abruptly contracted into a claw_ at base; _sterile filaments 3 in each set; leaves rounded, kidney-shaped_; otherwise as in the foregoing.--High mountains of Va. and N. C.

10. HYDRaNGEA, Gronov.

Calyx-tube hemispherical, 8--10 ribbed, coherent with the ovary, the limb 4--5-toothed. Petals ovate, valvate in the bud. Stamens 8--10, slender. Capsule 15-ribbed, crowned with the 2 diverging styles, 2-celled below, many-seeded, opening by a hole between the styles.--Shrubs, with opposite petioled leaves, no stipules, and numerous flowers in compound cymes. The marginal flowers are usually sterile and radiant, consisting merely of a showy membranaceous and colored flat and dilated calyx. (Name from ?d??, _water_, and ?????, _a vase_, from the shape of the capsule.)

1. H. arborescens, L. (WILD HYDRANGEA.) Glabrous or nearly so, 1--8 high; leaves ovate, rarely heart-shaped, pointed, serrate, _green both sides_; cymes flat; flowers often all fertile, rarely all radiant.--Rocky banks, Penn. to Fla., west to Iowa and Mo.

2. H. radiata, Walt. Leaves _densely tomentose and paler or white beneath_.--S. C. and Ga. to Tenn. and Mo.

11. DEc.u.maRIA, L.

Flowers all fertile. Calyx-tube turbinate, 7--10-toothed, coherent with the ovary. Petals oblong, valvate in the bud. Stamens 20--30. Styles united into one, persistent. Stigma thick, 7--10-rayed. Capsule 10--15-ribbed, 7--10-celled, many-seeded, bursting at the sides, the thin part.i.tions at length separating into numerous chaffy scales.--A smooth climbing shrub, with opposite ovate or oblong entire or serrate leaves, no stipules, and numerous fragrant white flowers in compound terminal cymes. (Name said to be derived from _decem_, ten, referring to the fact of its being often 10-merous.)

1. D. barbara, L. Leaves s.h.i.+ning, sometimes p.u.b.escent; capsule with the persistent style and stigma urn-shaped, pendulous.--Banks of streams; Dismal Swamp, Va., to Fla. and La.

12. PHILADeLPHUS, L. MOCK ORANGE or SYRINGA.

Calyx-tube top-shaped, coherent with the ovary; the limb 4--5-parted, spreading, persistent, valvate in the bud. Petals rounded or obovate, large, convolute in the bud. Stamens 20--40. Styles 3--5, united below or nearly to the top. Stigmas oblong or linear. Capsule 3--5-celled, splitting at length into as many pieces. Seeds very numerous, on thick placentae projecting from the axis, pendulous, with a loose membranaceous coat prolonged at both ends.--Shrubs, with opposite often toothed leaves, no stipules, and solitary or cymose-cl.u.s.tered showy white flowers. (An ancient name, applied by Linnaeus to this genus for no obvious reason.)

1. P. inodrus, L. _Glabrous_; leaves ovate or ovate-oblong, pointed, entire or with some spreading teeth; flowers single or few at the ends of the diverging branches, pure white, scentless; _calyx-lobes acute_, scarcely longer than the tube.--Mountains of Va. to Ga. and Ala.

2. P. grandiflrus, Willd. A tall shrub, with long and recurved branches; like the last, but _somewhat p.u.b.escent_, with _larger flowers_, and the _calyx-lobes long and taper-pointed_. (P. modorus, var. grandiflorus, _Gray_.)--Along streams, Va. to Fla. Often cultivated.

P. CORONaRIUS, L., the common MOCK ORANGE or SYRINGA of cultivation, from S. Eu., with cream-colored odorous flowers, has sometimes escaped.

13. iTEA, Gronov.

Calyx 5-cleft, free from the ovary or nearly so. Petals 5, lanceolate, much longer than the calyx, and longer than the 5 stamens. 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. Virginica, 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. RBES, 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 placentae 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 alb.u.men.--Low, sometimes p.r.i.c.kly 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 cl.u.s.ters, 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. GROSSULaRIA. (GOOSEBERRY.) _Stems mostly bearing thorns at the base of the leafstalks or cl.u.s.ters of leaves, and often with scattered bristly p.r.i.c.kles; berries p.r.i.c.kly 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 p.r.i.c.kly._
