This species is nearly allied to R. alpina, Linn., to which it is 

 united by De Candolle. It differs from it in the more oval-shaped 

 fruit, and the larger and more numerous prickles, and setae, which are 

 rarely found on R. alpina.

Root with long creeping suckers. Shrub from six inches to three 

 and four feet high, branches numerous, much divided, rigid, spreading. 

 Prickles mostly very numerous, crowded, slender, the larger ones often 

 dilated at the base, and slightly curved, usually they are straight, very 

 unequal in size, diminishing into bristles, the lower branches are often 

 naked, and sometimes, but rarely, the upper also. Leaves generally 

 very numerous, the common footstalk smooth, or with a few prickles 

 upon it. Leaflets small, flat, leathery, dull green above, paler beneath, 

 quite smooth, without glands, or hairy on the under surface, of an 

 orbicular obtuse, or ovate and acute shape, the margin simply, some* 

 times very finely doubly serrated and irregular. Stipules narrow, with 

 dilated spreading points, the margins with a glandular fringe. Flowers 

 numerous, solitary, terminal. Peduncles gradually thickening up- 

 wards, aud becoming coloured with the fruit, smooth, glandulous, or 

 sometimes bristly or prickly. Calyx with a globose tube, and simple 

 tapering segments, more or less iringed with glandular teelh, and 

 sometimes with short pinnae, or dilated at the point. Petals of a pale 

 cream colour, yellowish at the base, and blotched or striped with pink, 

 externally, more rarely altogether pink. Stigmas mixed with hairs, 

 pale or pink, prominent, or depressed. Fruit very variable in size, 

 globose, ovate, obovate, or more rarely urceolate, and though generally 

 of dark purple almost black colour, it is not unfrequently of a blood 

 red, firm when ripe with a sweet pleasant taste, crowned with a thick- 

 ened ring, and the erect or somewhat spreading calyx segments, often 

 thickened at the base.
