2. CLEÒME, L.
Petals entire, with claws. Stamens 6. Receptacle somewhat produced between the petals and stamens, and bearing a gland behind the stipitate ovary. Pod linear to oblong, many-seeded.—Our species a glabrous annual, with 3-foliolate leaves, leafy-bracteate racemes, and rose-colored or white flowers. (Name of uncertain derivation, early applied to some mustard-like plant.)
1. C. integrifòlia, Torr. & Gray. Calyx 4-cleft; petals with very short claws, leaflets narrowly lanceolate to oblong; bracts simple; pod oblong to linear, 1–2´ long, the stipe as long as the pedicel.—Minn. to Kan. and westward; N. Ill. Flowers showy; 2–3° high.
(Addendum) C. spinòsa, L. Viscid-pubescent, 3–4° high; a pair of short stipular spines under the petiole of each leaf; leaflets 5–7, oblong-lanceolate; flowers large, rose-purple to white; stamens 2–3´ long; stipe of the linear pod about 2´ long. (C. pungens, Willd.)—An escape from cultivation, near Mt. Carmel, Ill. (Schneck), and in waste grounds southward; also on ballast. (Int. from Trop. Amer.)
3. CLEOMÉLLA, DC.
Differing from Cleome in the clawless petals, glandless receptacle, and the short few-seeded pod with more or less distended or even conical valves. Flowers small, yellow. (Name a diminutive of Cleome.)
1. C. angustifòlia, Torr. Glabrous, 1–2° high; leaflets (3) and simple bracts linear to linear-lanceolate, acute; pod rhomboidal, the valves very bluntly conical; stipe shorter than the pedicel.—Kan. to Tex. and westward.
Order 12. RESEDÀCEÆ. (Mignonette Family.)
Herbs, with unsymmetrical 4–7-merous small flowers, a fleshy 1-sided hypogynous disk between the petals and the (3–40) stamens, bearing the latter. Calyx not closed in the bud. Capsule 3–6-lobed, 3–6-horned, 1-celled with 3–6-parietal placentæ, opening at the top before the seeds (which are as in Order 11) are full grown.—Leaves alternate, with only glands for stipules. Flowers in terminal spikes or racemes.—A small and unimportant family, of the Old World, represented by the Mignonette (Reseda odorata) and the Dyer's Weed.
