attention must be paid, although the former. perhaps always in 
some degree accompanies the hirsuties of the footstalk. On the 
stem, peduncle and fruit, pubescence is too rarely exhibited in 
British Roses for me to form any estimate of its value. On- the 
other hand, R. arvensis is the only British Rose of which the styles 
are smooth, and the seeds in all of them are villous. The white 
interchangeable with them ; the hairs on the axillz of the leaflets, 
and those which are occasionally to be met with along the upper 
surface of the midrib, are I believe.common to all Roses; and can 
therefore be of no use in distinguishing the species. The chafliness 
3s only met with in one tribe, where it is somewhat uncertain, and 
which is besides characterized by much more important distinc- 
tions. 
The appropriate name for the wre of a Rose during the inflo- 
rescence has been long a subject of contention among botanists; 
a circumstance which may be considered as a proof of the insuf- 
ficiency of the Linnean terminology in this respect. Linnæus 
himself called it the germen. Sir J. E. Smith, aware of the im- 
-propriety of this term, drew all his specific characters of this part 
from the fruit, not adverting to its appearance in an earlier stage: 
4n the detailed description he still preserves the word germen. 
Willdenow continues the use of this word, although he censures 
Linnæus for adopting it. Jussieu and Gærtner call it simply 
calyx, describing the genus as having calyx urceolaris. © ‘The French 
botanists. call it the tube of the calyx: but, according to general 
apprebension, the calyx would consist merely of those five leaves 
which form the outer envelope of the flower; and even after a 
‘strict attention to botanical terms, a student would be apt to.con-
