Of this plant I have seen no specimens, l)ut Mr. Baker lias 

 examined those in Mr. AVincli's collection at Newcastle, and con- 

 siders them quite distinct from R. spinosissima, receding from it in 

 the direction of 11. alpina. Similar plants are found on the Swiss 

 Alps, which are considered by M. llcuter as hybrids betwe(>n these 

 two species : possibly there may have been sonic mistake about the 

 locality of Mr. Winch's specimens ; as all the other British speci- 

 mens supposed to belong to li. rubella belong to R. spinosissima.

 Baker, in Nat. 18G4, p. 22. 



Prickles scattered, rather few and slender, straip;ht or curved, 

 unequal, passing gradually into aciculi and few gland-lipped setae. 

 Leailets oval, acutely and nearly equally serrate, gla])rous on both 

 sides, or with the principal veins hairy beneath, serratures occa- 

 sionally gland-tipped. Pedicels solitary or several together, with 

 bracts when more than one, glabrous. Fruit erect, urceolate sub- 

 globose, glabrous, red. Sepals persistent, leaf-pointed, frequently 

 slightly pinnatifid, without gland-tipped setae on the back. 



Mr. Baker distinguishes the following forms : — 



1. Rosa eu-hibernica. Baker, 1. c. p. 24. 

 Peduncles naked. Petioles hairy. Leaves hairy beneath. 

 Vale of Lorton, Cumberland ; near Belfast, and County Down ? 



2. Rosa glabra. Baker, 1. c. p. 24. 



Peduncles naked. Petioles and leaves hairless. 

 Yorkshire, Cheshire, and Surrey. 



3. Rosa cordifolia. Baker, 1. c. p. 24. 



Peduncles with aciculi and gland-tipped setae. Leaflets broader, 

 more bluntly serrate, hairy beneath, those of the barren shoots 

 subcordate at the base. Peduncles hairy.

A doubtful plant, intermediate between R. spinosissima and 

 R. Sabini, resembling the former in the shape and sen-ation of the 

 leaflets, the latter in general haliit, the prickles, the flowers not
