1. R. rubella. Red-fruited Dwarf Rose.
Fruit oval, somewhat bristly. Flower stalks, bristly. Stem spreading, clothed with straight slender spines. Leaflets elliptical, smooth, singly serrated. Segments of the calyx entire.

Eng. Bot. 2521 and 2601, Fruit f.3; With. iii. 613; Sm. Com. 78 ; Woods, Linn. Trans. xii. 177; Lindley, Mon. 40; Sm. Eng. Fl. ii. 374; Winch, Geog. Pl. 2nd ed., No. 1, App.; Hook. Br. Fl. 225.

Flowers white tinged with pink. Fruit, when ripe, pear-shaped, scarlet, and pendant. Calyx permanent.

On the sands of the sea coast near South Shields, D., mixed with the dwarf variety of the Burnet Rose, rare July 17, 1797.

This shrub appears a link between Rosa spinosissima and Rosa alpina; the latter of which it greatly resembles in habit. It is not Rosa pimpinellifolia of the Swiss Botanists, as Mr. Woods conjectures; for, by a specimen procured from Schleicher, that plant appears to be Rosa spinosissima. Nor is it Rosa spinosissima, var. 3, of Withering, as I am assured by that gentleman.

2. R. spinosissima. Burnet Rose.
Fruit globose, smooth as well as the flower stalks. Stem clothed with numerous straight slender spines. Leaflets singly serrated, smooth and round.

Brit. ii. 537; Lindley Mon. 50; Sm. Eng. Fl. ii. 375; R. pimpinellifolia, Linn. Syst. Nat. 10th ed., 1062; Schleicher's Catalogue, 24.

Flowers yellowish white. Fruit first reddish brown, as coloured in English Botany, and then turning black. Calyx permanent.

γ pusilla, Woods, Linn. Trans, xii. 179; Sm. Eng. Fl. ii. 376.

Flower stalks short. Fruit large, depressed.

The Burnet Rose is a shrub of a very diminutive growth on the sea beach (var. γ), but rises to a tall bush in woods and hedges distant from the coast. It is not very common, but occasionally to be found even in our sub-alpine vallies; and in the woods bordering the Lakes of Cumberland and Westmoreland. It may be met with about Newcastle, Corbridge, the Crag Lake, and on the coast at Holy Island, N. At Hebburn Quay, on the links near South Shields, at Norton; also in Weardale and Teesdale, D.

3. R. gracilis. Tall Bristly Rose.
Flower stalks bristly, generally bracteated. Branches, fruit and calyx bristly. Leaflets doubly serrated, hairy on both sides.
