Plant. - Bushy shrub, .6-1 M. (2-3°) high, stems numerous, covered with prickles and a few sharp spines; leaves alternate, imparipinnate, 2 pairs opposite leaflets, these nearly sessile, ovate, rounded at base, acute at apex, serrate, stiff, keeled, rugose, with veins, pale, hairy below, leaf-serratures not edged with glands; flowers large, on long stalks, petals 5 in the wild state, more when cultivated, rich-crimson; fruit (hip) scarlet to orange-red, oblong, containing many 1-seeded achenes, calyx persistent. Petals, either separate or imbricated in small cones, broadly ovate, summit rounded, deeply notched, margin entire, somewhat recurved, base obtuse, purplish-red except the light brown claw; texture velvety; when dry brittle; odor agreeable; taste astringent, slightly hitter. Powder, reddish-brown; microscopically - epidermal cells with purplish-red content (sap), fragments of fibro-vascu-lar bundles, spiral tracheae, rectangular cells with purplish content (sap). Solvents: boiling water; diluted alcohol. Dose, gr. 15-00 (1-4 Gm.). Commercial. - Plant, in its many species and varieties, very largely cultivated domestically as well as commercially; petals are obtained by circumcising with a sharp knife the unopened corolla-buds, leaving the stamens behind on the calyx; or the entire blooms are cut off with knives or scissors, dried carefully but rapidly by stove heat (in order to preserve astringency and color), sifted, if necessary, from stamens, etc., and marketed; early collection is more astringent and of better color, qualities impaired by slow drying. It is claimed that 1000 flower-buds yield 50 pounds (23 Kg.) of fresh petals, which when dried become 5 pounds (2.3 Kg.). Adulterations. - Petals of various red roses. Constituents. - Volatile oil (trace), mucilage, tannin (querci-tannic acid?), gallic acid, quercitrin, quercetin (astringent and coloring), sugar, ash 3.5 p. c.
