[+][+][+] _Flowers indigo-blue._

6. B. australis, R. Br. (BLUE FALSE-INDIGO.) Smooth, tall and stout (4--5); leaflets oblong-wedge-form, obtuse; stipules lanceolate, as long as the petioles, rather persistent; raceme elongated (1--2) and many-flowered, erect; bracts deciduous; stalk of the oval-oblong pods about the length of the calyx.--Alluvial soil, Penn. to Ga., west to S. Ind., Mo., and Ark.

2. THERMoPSIS, R. Br.

Pod sessile or shortly stipitate in the calyx, flat, linear, straight or curved. Otherwise nearly as Baptisia.--Perennial herbs, with palmately 3-foliolate leaves and foliaceous stipules, not blackening in drying, and yellow flowers in terminal racemes. (Name from ?????, _the lupine_, and ???? _resemblance_.)

1. T. mollis, M. A. Curtis. Finely appressed-p.u.b.escent, 2--3 high; leaflets rhombic-lanceolate, 1--3' long; stipules narrow, mostly shorter than the petiole; raceme elongated; pods narrow, short stipitate, somewhat curved, 2--4' long.--Mountains of S. Va. and N. C.

2. T. rhombiflia, Nutt. Low, with smaller leaves and broad conspicuous stipules; racemes short, few-flowered; pods broadly linear, spreading, usually strongly curved.--Sask. to E. Col., near or in the mountains, reported from central Kan.

3. CLADRaSTIS, Raf. YELLOW-WOOD.

Calyx 5-toothed. Standard large, roundish, reflexed; the distinct keel-petals and wings straight, oblong. Stamens 10, distinct; filaments slender, incurved above. Pod short-stalked above the calyx, linear, flat, thin, marginless, 4--6-seeded, at length 2-valved.--A handsome tree, with yellow wood, smooth bark, nearly smooth pinnate leaves of 7--11 oval or ovate leaflets, and ample panicled racemes (10--20' long) of showy white flowers drooping from the ends of the branches. Stipules obsolete. Base of the petioles hollow, enclosing the leaf buds of the next year. Bracts minute and fugacious. (Name from ???d??, _a branch_, and ??a?st??, _brittle_.)

1. C. tinctria, Raf. Sometimes 50 high; pods 3--4' long.--Rich hillsides, central Ky. and Tenn. to N. C. Also in cultivation. The wood yields a yellow dye.

4. SOPHRA, L.

Calyx bell-shaped, shortly 5-toothed. Standard rounded; keel nearly straight. Stamens distinct or nearly so. Pod coriaceous, stipitate, terete, more or less constricted between the seeds, indehiscent. Seeds subglobose.--Shrubby or ours an herbaceous perennial, the leaves pinnate with numerous leaflets, and flowers white or yellow in terminal racemes.

(Said by Linnaeus to be the ancient name of an allied plant.)

1. S. sericea, Nutt. Silky canescent, erect, 1 high or less; leaflets oblong-obovate, 3--6” long; flowers white; pods few-seeded.--Central Kan. to Col., Tex., and Ariz.

5. CROTALaRIA, L. RATTLE-BOX.

Calyx 5-cleft, scarcely 2-lipped. Standard large, heart-shaped; keel scythe-shaped. Sheath of the monadelphous stamens cleft on the upper side; 5 of the anthers smaller and roundish. Pod inflated, oblong, many-seeded.--Herbs with simple leaves. Flowers yellow. (Name from ???ta???, _a rattle_; the loose seeds rattling in the coriaceous inflated pods.)

1. C. sagittalis, L. Annual, hairy (3--6' high); leaves oval or oblong-lanceolate, scarcely petioled, stipules united and decurrent on the stem, so as to be inversely arrow-shaped; peduncles few-flowered; corolla not longer than the calyx; pod blackish.--Sandy soil; Maine to Ill., Minn., Kan., and southward.

6. GENiSTA, L. WOAD-WAXEN. WHIN.

Calyx 2-lipped. Standard oblong-oval, spreading; keel oblong, straight, deflexed. Stamens monadelphous, the sheath entire; 5 alternate anthers shorter. Pod mostly flat and several-seeded.--Shrubby plants, with simple leaves, and yellow flowers. (Name from the Celtic _gen_, a bush.)

G. TINCTRIA, L. (DYER'S GREEN-WEED.) Low, not th.o.r.n.y, with striate-angled erect branches; leaves lanceolate; flowers in spiked racemes.--Established on sterile hills, eastern N. Y. and Ma.s.s. (Adv.

from Eu.)

7. CTISUS, Tourn. BROOM.

Calyx campanulate, with 2 short broad lips. Petals broad, the keel obtuse and slightly incurved. Stamens monadelphous. Pod flat, much longer than the calyx. Seeds several, with a strophiole at the hilum.--Shrubs, with stiff green branches, leaves mostly digitately 3-foliolate, and large bright yellow flowers. (The ancient Roman name of a plant, probably a Medicago.)

C. SCOPaRIUS, Link. (SCOTCH BROOM.) Glabrous or nearly so (3--5 high); leaflets small, obovate, often reduced to a single one; flowers solitary or in pairs, on slender pedicels, in the axils of the old leaves, forming leafy racemes along the upper branches; style very long and spirally incurved.--Va. and southward. (Nat. from Eu.)

8. LUPNUS, Tourn. LUPINE.

Calyx very deeply 2-lipped. Sides of the standard reflexed; keel scythe-shaped, pointed. Sheath of the monadelphous stamens entire; anthers alternately oblong and roundish. Pod oblong, flattened, often knotty by constrictions between the seeds. Cotyledons thick and fleshy.--Herbs, with palmately 1--15-foliolate leaves, stipules adnate to base of the petiole, and showy flowers in terminal racemes or spikes.

(Name from _Lupus_, a wolf, because these plants were thought to devour the fertility of the soil.)
