114 ROSA ARVENSIS. 
A very common plant in many parts of England, 
adorning the hedges in the summer months with its 
elegant, snowy bloom. The flowers are much more 
cup-shaped than those of systyla, or indeed of any 
other British Rose. Mr. Sabine has a variety with 
pink flowers. 
Dr. Afzelius considered the Linnzean arvensis to be 
something different from our plant, which does not grow 
in Sweden; and possibly that variety of cinnamomea 
which is figured in Flora Danica under the name of R. 
Jluvialis. The Linnzan herbarium throws no light 
upon this, nor have I any additional facts to offer in il- 
lustration of it. 
The styles united in a long smooth column, incor- 
rectly described by Sir James Smith as lengthening 
after flowering, distinguish this from all the British 
Species except the last.. From that it differs in having 
long trailing shoots, not stout assurgent ones, which 
are dull glaucous green, generally tinged with purple, 
and not of the bright green colour of systyla.. 
To this species the Ayrshire Rose of the gardens is 
undoubtedly to be referred, as has already been done 
by Dr. Sims. Of this plant, however, there are two 
sorts; thé one sold in the nurseries about London, and 
cultivated by Mr. Sabine, I suppose is to be considered 
the real kind ; and, as I have just observed, is a variety 
of arvensis ; the other, which is cultivated at Kew, is 
sempervirens, from which it does not appear to differ in 
any respect. This has been considered as the real 
Ayrshire and published as such under the name of ca- 
preolata in the Edinburgh Philosophical Journal, by 
Mr. Neill, who assures us that it received its name 
from having been first raised at Loudon Castle, Ayr- 
shire, from heps imported from N. America. Without 
attempting to dispute the accuracy of this, I must ob- 
Serve, that if the seeds were brought from America, 
they were carried thither originally from Europe. 
_ From R. sempervirens there can be no difficulty in 
distinguishing arvensis. The leaves of the former are
