220 Mr. Woods on the British Species of Rosai 



Flowers sometimes white, sometimes of a full blush-colour. 

 Fruit often subglobose. Hedges throughout England very 

 common. 



J. A compact bush three or four feet high, thick with leaves, the 

 leaflets small, very acute, silky underneath. Near Dovedale, 

 Derbyshire. 



There .is no species of Rosa in which my endeavours have been 

 more unsuccessful than in this. I am neither satisfied in what I 

 have joined together, nor in the marks by Avhich I have attempted 

 to discriminate it from other species. The variety « is adopted 

 merely from Jacquin ; and, as far as is at present known, is not a 

 British plant. I have therefore drawn up my description from the 

 variety /3: an examination of the specimens of -R. collina possessed 

 by Sir J. E. Smith, and of those in the Herbarium of Sir Joseph 

 Banks, and a comparison of these with the figure in the Flora Aii- 

 striaca, enable me to state that this variety differs only from a in 

 the want of hairs or glands on the peduncle. In this state it ap- 

 proaches very nearly to R. bractescens, being scarcely distinguish- 

 able, except by the somewhat smaller bractea; and the entire 

 nakedness of the upper surface of the leaf; and as that species 

 has frequently a glandular, or rather a weakly setose peduncle, 

 exactly like that of Jacquin's figure, I have doubted whether 

 I ought not rather to have attributed the name and synonym to 

 that plant. Jacquin, however, could hardly have passed unno- 

 ticed the remarkably enlarged bractescent stipulae accompanying 

 the inflorescence of R. bractescens; he describes the prickles as 

 *' validi," although in the figure they are represented as much 

 weaker than is the case with most Roses of this subdivision of 

 the genus, and the folioles as " atro-virentia," whereas they are 

 figured pale and glaucous ; both figure and description attri- 

 bute a dark cartilagineous summit to the serratures. These cir- 

 cumstances
