Chapter L: STRIATA, Hook. & Arn. Diffusely branched, decumbent, subpubescent;

petioles very short; leaflets oblong-obovate, 6'' long or less; peduncles very short, 1--5-flowered; pod small, little exceeding the calyx.--Common in the Southern States, extending into Mo. (Nat. from E. Asia.)

29. STYLOSANTHES, Swartz.

Calyx early deciduous; tube slender and stalk-like; limb unequally 4--5-cleft, the lower lobe more distinct. Corolla and monadelphous stamens inserted at the summit of the calyx-tube; standard orbicular; keel incurved. Anthers 10, the 5 longer ones fixed near their base, and the 5 alternate shorter ones fixed by the middle. Style filiform, its upper part falling off after flowering, the lower part incurved or hooked, persistent on the 1--2-jointed small and short reticulated pod; the lower joint when present empty and stalk-like.--Low perennials, branched from the base, with wiry stems, pinnately 3-foliolate leaves, the sheathing stipules united to the petiole, no stipels, and small, yellow flowers in terminal heads or short spikes. (Name composed of [Greek: sty/los], _a column_, and [Greek: a)/nthos], _a flower_, from the stalk-like calyx-tube.)

1. S. elatior, Swartz. Tufted; leaflets lanceolate, strongly straight-veined; heads or clusters small and few-flowered.--Pine barrens, Long Island and N. J. to Fla., west to S. Ind., Kan., and Ark.

30. VICIA, Tourn. VETCH. TARE.

Calyx 5-cleft or 5-toothed, the 2 upper teeth often shorter, or the lowest longer. Wings of the corolla adhering to the middle of the keel. Stamens more or less diadelphous (9 and 1); the orifice of the tube oblique. Style filiform, hairy all round or only on the back at the apex. Pod flat, 2-valved, 2--several-seeded. Seeds globular. Cotyledons very thick, remaining under ground in germination.--Herbs, mostly climbing more or less by the tendril at the end of the pinnate leaves. Stipules half-sagittate. Flowers or peduncles axillary. (The classical Latin name.)

[*] _Annual; flowers 1 or 2 in the axils, nearly sessile, large, violet-purple._

V. SATIVA, L. (COMMON VETCH or TARE.) Somewhat pubescent; stem simple; leaflets 5--7 pairs, varying from obovate-oblong to linear, notched and mucronate at the apex; pod linear, several-seeded.--Cultivated fields and waste places, N. Eng. to N. J. and southward, west to Mich. and Minn.--Var. ANGUSTIFOLIA, Seringe, has longer and narrow leaflets. (Adv. from Eu.)

[*][*] _Annual, slender; peduncles elongated; flowers small._

V. TETRASPERMA, L. _Peduncles 1--2-flowered_; leaflets 4--6 pairs, linear-oblong, obtuse; calyx-teeth unequal; corolla whitish; _pods narrow, 4-seeded, smooth_.--Waste places, near the coast, N. Scotia to N. J. (Nat. from Eu.)
