Rosae Caninae Fructus. Hips.
Hips are the fresh fruits of Rosa canina, Linn. (N.O. Rosaceae), and other indigenous allied species. The ripe fruit of the dog rose is ovoid, smooth, shining, and of a scarlet or red colour. It is crowned with five calyx teeth, beyond which a dense tuft of short styles protrudes. The fruit consists of the fleshy, hollow receptacle (to which the calyx tube is united), bearing on its inner surface a number of small, hairy achenes. It has an agreeable, acid taste. The fruit of the field rose, R. arvensis, Huds., resembles that of the dog rose, but is nearly globular, and the styles of the achenes protrude in the form of a column. No other English wild roses occur in sufficient abundance to furnish an appreciable quantity of fruit.
Constituents.—Hips contain malic and citric acids, sugar, and a trace of tannin.
