all this family ; and the straight prickles render it impossible 
to mistake it for thatspecies. If distinct, its place would be 
before R: villosa, as nearer to the family of R. spinosissima, 
The stipulz are almost membranous, which would form an 
. excellent character if it should be found constant. I have 
only seen it in one place, on a rocky limestone bank at Ingle- 
ton in Yorkshire ; and at that time I was so puzzled by the 
multifarious appearance of thie specimens I had collected, and 
which I had not had opportunity to arrange, that I did not 
pay it the attention it merited, and only preserved a single 
— specimen. | 
It is with considerable doubt that I have quoted R. pomifera, 
Fl. Bad. Alsat., as a synonym of this species. The author says, 
that sometimes two of the calyx-leafits are divided, which might 
have induced me to refer it to R. scabriuscula ; especially as the 
name seems to indicate a large-fruited Rose; and the fruit of 
R. scabriuscula is occasionally very large; but in other respects 
it does not agree with that plant. | 
- I hesitate still more whether R. glandulosa, Lam. et Dec. Fl. 
Fr. vi. 539, ought to be considered as a smooth variety of tbis 
plant: it certainly approaches FER near to it, except in the P 
bescence. £

dwarf variety of this species. Here again the descriptor * foliolis 
glabris inodoris" renders it ad doubtful.
