It agrees well with the description, but the prickle-bases 
do not appear unusually elongate. The leaflets are rather small, 
narrow, and very close set, very thinly hairy above, finely but 
densely pubescent and eglandular beneath, just like those of cesza, 
but they are fully biserrate. The petioles are densely pubescent 
and glandular, but not at all prickly. The fruit is remarkably large 
and oblong, on short, slightly hairy peduncles. The sepals are 
very long, reflexed, but persistent, aS but glabrous

eyond those already mentioned as probably synonymous with 
British species, I know of no foreign species which there is special 
reason to suppose may be found in Britain, though a considerable 
number are named. 
ConcLUDING REMARKS. 
I fear this paper has reached a considerably greater length 
than I at ‘at HAE intended, and perhaps if I had confined myself to 
collating and publishing authors’ descriptions, it might have been 
equally useful. A distinguished botanist has said that the de- 
scriptions of individual roses are worth less than the paper they 
are written on, but I have given pie on a good sereagel partly to 
supplement the authors’ descriptions, an oer partly to show what 
degree of variation is permissible. If, however, I had admitted 
every available specimen by authors of repute, it would have been 
obvious that the limita of the species were so wide that one would 
have been eh to adopt Crépin’s plan in his later years of 
refraining from naming varieties ‘i all, but referring them to 
groups only; dudecd it is hy no ee — easy to correctly
