In the western part of Scotland. 



Found in several parts of the Hebrides, by the late Rev. Dr. 

 Walker, and Mr. J. Mackay. The Rev. Dr. Stuart is recorded, 

 by Mr. Woods, as having gathered it in Glen Lyon ; and Mr. 

 G. Don in the isle of Arran. 



Shrub. June. 



Akin to the last, the stem, as in that, hearing innumerable crow^ded, 

 slender, very unequal, nearly straight prickles, intermixed with 

 glandular bristles, both which are likewise observable on the 

 downy footstalks. Leaflets 7, rarely 9, broadly elliptical, doubly 

 and sharply serrated, the intermediate serratures numerous and 

 glandular ; green and smooth on both sides, except the rib and 

 veins which are densely hairy beneath, sometimes above. Sti- 

 pulas seldom changing to bracteas. Flower -stalks solitary, 

 thickly covered with strong glandular acute bristles, as is almost 

 universally the globular tube of the calyx, whose segments are 

 long, bristly, for the most part simple, but in one of my garden 

 specimens fringed with a few narrow glandular leaflets. Petals 

 pale red, sometimes deeper at the margin, all concave, and 

 scarcely half-expanded. Styles short. Ripe fruit not hitherto 

 observed. 



5. R. Doniana. Dwarf Hairy Rose. 



Flower-stalks generally without bi-acteas, bristly, like the 

 globular fruit and simple calyx. Stem bristly and prickly, 

 like the downy footstalks. Leaflets elliptical, doubly and 

 sharply serrated, hairy on both sides. Petals spreading.

R. Sabini. Purton v. 3. 44 ; according to Mr. Sabine. 



In the Highlands of Scotland. 



On the mountains of Clova, Angusshire. Mr. G. Don. 



Shrub. June, or July. 



Stem about 2 to 5 feet high, less extensively creeping at the root, ac- 

 cording to Mr. Don's observation, than the last, and less prickly 

 in the upper part. The leaflets are clothed with fine soft hairs 

 on both sides, not merely the ribs or veins ; and the^owers are 

 distinguished by their white expanded petok. The radical shoots, 

 though very prickly, are described by Mr. Woods as less so than 

 those of R. involuta. The sharp double serratures of the leaves 

 are alike in both, and essentially distinguish these two species 

 from the spinosissima. Of their ripe fruit we have no account, 

 nor have I seen more than a dried specimen of R. Doniana. 



It is much to be wished that this Rose should afford a permanent 

 \vreath in honour of its discoverer, one of the most indefatigable
