and R. mollis. We reserve our remarks on these errors for 

 another work. 



One meets on the Alps with forms which appear inter- 

 mediate between R. glauca (including R. coriifolia) and 

 R. canina (including R. dumetorum). These forms, which 

 have received the names of R. subcanina (R. glauca, var. sub- 

 canina, Christ) and of R. subcollina (R. coriifolia, var. sub- 

 collina, Christ), should be sought for in England. 



Rosa rubiginosa, Z. 



The " London Catalogue of British Plants " ranks R. 

 permixta, Desegl., among the varieties of R. rubiginosa; but the 

 plant of Deseglise is unquestionably a variety of R. micrantha, 



Rosa mierantha, Sm. 



The form referred to R. micrantha under the name of 

 var. Briggsii, Baker, is extremely curious because of its smooth 

 pedicels. It seems indeed to be a variety of Smith's type ; 

 but it will require of the monographer a profound study before 

 it can be definitely accepted as such. 



Rosa sepium, Thuill. 



R. scpiuni, Thuill (R. agrestis, Savi), appears to be rare 

 in the British Islands. On the Continent one see this species 

 become more and more rare in proportion as one advances 

 northwards. Even in Belgium it is extremely rare. In the 

 north of Germany,in Denmark, and in the south of Scandinavia 

 it is replaced by a variety of R. graveolens, Gren., known 

 under the name of R. inodora, Fries. R. graveolens being a 

 mountain species, its existence in the north is naturally 

 explained. Does it exist in the British Islands? It would 

 seem so, if one rely on Mr. Baker's monograph and on 

 the London Catalogue ; but as yet I have no proof of the 

 existence of this species in England. 



Rosa tomentosa, Sm. 



is widely distributed in England, Scotland, and Ireland. It 

 inhabits the plains rather than the mountains, at least in the
