A beautiful flower, adorning our woods in May and June. Stem 8 - 12' high, with a whorl of 3 broad-ovate leaves at top. These are 3-veined, rounded at base, long acuminate, 3 - 4' long, 2/3 as wide, petiole 2 - 3" long. Flower nearly erect. Petals wavy at the edges, white, finely radiated with purple lines at base. The root is considered medicinal. (T. pictum Ph.)

β . clevelandicum. Sepals leaf-like, larger than the petals which are partly or , chiefly green. - Brunswick, Me. (Ricard). A metamorphosis.

5 T. grandifolium Salisb. Lvs. broadly rhomboid-ovate, subsessile, abruptly acuminate; ped. inclined; fl. suberect; petals mvch longer than the calyx, spatu-late-obovate, connivent at base. - Damp, rocky woods, Mid., S. and W. States, abundant. St. 8 to 12' high. Lvs. 3 to 5' diam. Fls. larger than in any of the preceding species. Petals 1 1/2 to 2' in length, broadest near the apex, with a short, abrupt acumination, white, varying to rose-colored. May.

6 T. erectuni L. Bath Flower. St. thick; lvs. rhomboidal, acuminate, sessile; ped. inclining; fl. nodding; petals ovate, acute, scarcely longer, but much broader than the sepals. - A conspicuous plant in woods, of fine appearance, but offensive odor. At the top of the stem, which is a foot high, is a whorl of 3 leaves which are 3-veined, 3 - 5' long, of equal width, and a single, nodding flower, on a nearly erect peduncle. Petals broad-ovate, an inch long, twice as wide as the sepals and of a dusky purple, greenish outside. May. (T. atropurpureum Curt.)

Car. (Miss Carpenter) to Ga. (Mr. Jones). A small plant with a largo flower. St. 8 to 10' high. Lvs. 2 to 3' by 20 to 30". Petals roseate, 15 to 18" long. Apr. - Jn. (T. Catesbsei Ell.)

2. MEDE'OLA, Gronov. Indian Cucumber-root. (Named after the fabulous sorceress, Medea, for its supposed medicinal virtues.)

Fls. in the upper whorl, 1, 2 or 3, pendulous, with greenish, revolute segments. The stigmas are very long, rerlexed, dark red. Jl.
