9. CER'CIS, L. Judas Tree. Red-bud. (Gr.14 Loteae Part 3 521 a weaver's shuttle; sc. the legumes.) Calyx broadly campanulate, 5-toothed; petals scarcely papilionaceous; all distinct; wings longer than the vex-illum and smaller than the keel petals; stamens 10, distinct; legume compressed, with the seed-bearing suture winged; seeds obovate. - Trees with simple, cordate lvs. and rose-colored fls.

C. Canadensis L. Lvs. broadly ovate-cordate, acuminate, villous on the veins beneath. - A handsome tree, 20 to 30f high, Mid. and W. States. The wood is finely veined with black and green, and receives a fine polish. Lvs. 3 to 4' by 4 to 5', entire, smooth, 7-veined, on petioles 1 to 2' long. The flowers appear in advance of the leaves, in small, lateral clusters, clothing the whole tree in purple, in early Spring. The young twigs will dye wool a nankeen color. The old author Gerarde in compliance with the popular notion of his time, says " This is the tree whereon Judas did hang himself, and not on the elder tree, as it is said."

10. CLADASTRIS, Raf. Yellow-wood. Calyx 5-toothed, teeth short, obtuse; petals of nearly equal length, those of the keel distinct and straight like the wings; vex. large, roundish, reflexed; stam. 10, distinct; filaments glabrous, incurved, legume flat and thin, short-stiped, 5 or 6-seeded. - A tree with yellow wood, pinnate lvs., and pendulous clusters of white fls.

C. tinctoria Raf. Hills, in rich soils. W. Ky. and W. Tenn. Tree 20 to 40f high, with a smooth greenish bark. Lfts. 7 to 11, stalked, oval, acuminate, 3 to 4' long. Rac. 6 to 10' long, compound, thyrse-like, showy, resembling those of the common locust. Leg. as long as the leaflets, very narrow. Apr., May.

11. BAPTIS'IA, Vent. Wild Indigo. (Gr.14 Loteae Part 3 522 to dye; a use to which some species are applied.) Calyx 4 to 5-cleft half way, persistent; petals of about equal length, those of the keel nearly distinct and straight; vexillum orbicular, emarginate; stamens 10, distinct, deciduous; legume inflated, stipitate, many (or by abortion few)-seeded. - 14 Loteae Part 3 523 Lvs. palmately 3-foliate, or simple.
