In "Review of the British Roses, Especially Those of the North of England," by J. G. Baker, Part IV, CANINAE, at p. 93:
R. Canina Linn.
The plants included here differ from one another widely, if we take the extremes, in many points of importance, especially in the shape, toothing and clothing of the leaves and stipules, the texture and time of ripening of the fruit, and the direction and duration of the sepals; but in spite of this, each of them is always connected with the one that is nearest to it very closely. We have here an excellent illustration of what one school of botanists considers to be a single variable species, and what another school considers to be a large group of closely allied species.
R. uncinella Bess.
Habit of growth and prickles of the normal R. canina. Leaves flat, grey-green, slightly hairy on the upper surace when young, but glabrous when mature, greyer still and hairy all over beneath, so that the edge is ciliated, firm in texture, the serrations simple, spreading and open, as broad as they are deep, callous at the tips, the terminal leaflet broadly oval or obovate, much rounded at the base; the petioles villous, but hardly at all glandular, funished usually with 2 or 3 hooked prickles. Stipules and bracts slightly hairy on the back, dentate but hardly at all gland-ciliated. Peduncles naked. Calyx-tube and fruit large, broadly elliptical or subglobose, the green fuit rather more pliable than in R. platyphylla. The sepals reflexed after the petals fall, leaf-pointed and fully pinnate, tomentose, and slightly glandular on the back, hardly at all setoso-ciliated. Styles villous.
