178 ANNALS OF SCOTTISH NATURAL HISTORY 



a form of R. coriifolia, Fr., but differs from the two previously 

 mentioned in having the pedicels and backs of the sepals 

 thinly glandular. In the Kew Herbarium is a similar speci- 

 men labelled " Taynuilt H. C. D. Turner." 



Besides these type specimens, there were both at Kew 

 and at South Kensington other specimens gathered in various 

 parts of England by various collectors, and named R. ccesia, 

 Sm. In most cases these were, I think, forms of R. coriifolia, 

 Fr., but several of them were, in my judgment, forms of 

 R. tomentosa, Sm. 



In the " Revision des Rosa de 1'herbier Babington," 

 M. Crepin says that R. pruinosa, Baker, is also probably a 

 variety of R. coriifolia, Fr. Mr. Baker, in his paper, identifies 

 with his var. pruinosa those forms of R. ccesia, Sm., which 

 have the pedicels eglandular, for he quotes R. cassia, Borrer, 

 "Brit Flora," edit 3, page 242 (ex part e]. If so, then the 

 two type specimens of R. c&sia, Sm., which I have mentioned 

 first, would be classed as var. pruinosa ; and, as I have said, 

 these are, in my opinion, forms of R. coriifolia. At Kew I 

 did not see any specimens named var. pruinosa. At South 

 Kensington there were two bearing that name, both gathered 

 in 1884 by E. F. Linton : one in Braemar, the other in Glen 

 Shee. The first is R. coriifolia, with composite-glandular 

 toothing and leaflets glandular below ; the other is similar, 

 but without glands on the under surface of the leaflets. 



It would appear then that M. Crepin is right in saying 

 that var. pruinosa, Baker, is a variety of R. coriifolia, Fr. I 

 may add that No. 77 of Woods' collection, gathered near 

 Edinburgh by Mr. Borrer and described in the " British Flora " 

 as R. Borreri, Woods, var. J3, appears to me to be likewise a 

 form of R. coriifolia, Fr., with composite-glandular toothing 

 and leaflets glandular below. 



The uncertainty which has so long prevailed regarding 

 R. ccesia, Sm., and its variety incana, Woods, has undoubtedly 

 resulted from the fact that the specimens on which they were 

 founded exist only in flowers or in immature fruit Had 

 authentic specimens existed showing the mature fruit, the 

 identity of these with R. coriifolia, Fr., must have been long 

 ago perceived. R. coriifolia is very abundant in Scotland, 

 and its variations are manifold. These have been grouped
