Root with creeping suckers. Shrub from five to eight or ten feet 

 high, erect, with spreading somewhat drooping much divided branches, 

 with reddish brown coloured bark. Prickles numerous on the stem, 

 few, and scattered on the branches, very unequal in size, and with but 

 few setae amongst them ; they are all nearly straight in a. and jS- > 

 but in y. the larger ones are much more curved than the smaller. 

 Leaves numerous, with the common footstalk having a few slender 

 straight prickles, and setae also hairy and glandulose. Leaflets from 

 seven to nine, elliptic, or ovate, with an acute point, the margins 

 sharply and acutely doubly serrated, more or less hairy above, paler 

 and more hairy beneath, the margins, ribs, and veins scattered over 

 with a greater or less number of glands. Stipules pale, dilated up- 

 wards and spreading at the point. Flowers solitary, or two or three 

 together in bunches. Peduncles equal, more or less setose, as well as 

 the calyx tube, and accompanied with one or two serrated bractea, 

 hairy and glandulous on the margins and ribs. Calyx segments 

 copiously pinnated, mostly with a long dilated leafy point, rarely 

 simple, hairy, setose, and glandulous. Petals longer than the calyx 

 segments, varying in colour from pink to white, often mottled or 

 striped. Stigmas more or less protruded. Fruit globose, or somewhat 

 urceolate, of a fine dark red colour, crowned by the persistent calyx 

 segments, and more or less scattered over with setae. 



Habitat. — North of England and Scotland, and Umbra rocks, 

 Magilligan, Ireland, with the following var. /5. Sussex, Warwick-

 Lorton. — Mr. Wood. Bennedy Glen, near Dungiven, Ireland. —

Shrub ; flowering in June. 



Such are the difficulties in discriminating the species of this genus, 

 that Professor Lindley, who, by his monograph, has done more to eluci- 

 date the Rose than any other Botanist, asks of the above species, 

 " Can this be, after all, a production of R. tomentosa mollis ?" 



3. ViLLOs^. Branches withoxU setce. Prickles nearly straight, 

 equal. Leaflets with diverging serratures, and glandulous. Calyx 

 segments persistent. Disk thick^ closing up the mouth of the tube.
