Mr. Woops on the British Species of Rosa. 189 
segments may I believe always be observed if examined with at- 
tention ; but they are sometimes so strictly capillary as hardly to 
be distinguished from very large and long sete. 
This Rose does not seem to have been before noticed ; I have 
therefore given to it the name of a gentleman who has long culti- 
vated and investigated the characters, principally of the foreign 
Roses, with the greatest care. "The result of his labours will not 
I hope be long withheld from the public. It is by his assistance 
that I am enabled to distinguish this species from all others. 
This species and the five preceding form the English portion of 
the family of R. spinosissima. R. rubella, R. spinosissima, R. invo- 
luta, R. Doniana, R. gracilis, and R. Sabini, all agree in having 
persistent setæ on the stems and branches, the stipulæ not in- 
creasing in breadth towards the inflorescence, or only in a slight 
degree, the flowers few together, and the fruit nearly round. I 
have already mentioned how slight my knowledge is of the exotic 
species; and perhaps in this subdivision I have fewer materials 
of comparison than in any other; but considering that the more 
completely I exhibit my ideas on the subject of the arrangement 
of the genus, the better chance I have of making my principles 
understood, I venture to mention R. kamschatica as the only 
foreign addition to the tribe at present known. |
