Mr. Woods on the British Species of Bosa. 165 



Httention must be paid, altliougli 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, B. arvensis isjthe only British Rose of which the styles 

 are smooth, and the seeds in all of them are villous. The white 

 hairs which occupy the place of glands are always more or less 

 interchangeable with them ; the hairs on the axilla? 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 chaffiness 

 is 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 iiip 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 Linnasan terminology in this respect. Linnaeus 

 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: 

 in the detailed description he still preserves the word germen. 

 Willdenow continues the use of this word, although he censures 

 Linnaeus for adopting it. Jussieu and Gaertner 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 

 apprehension, 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- 

 clude the fleshy body separated by its substance, and apparently
