I have not been able to meet with that part of La- 
peyrouse’s Flora of the Pyrenées in which this Rose is 
figured. From his description it is R. cinnamomea in 
every respect except having the stalk of the upper 
leaves lengthened out into a spine. Whatever it be, 
whether a monstrous or natural appearance, the above 
character is sufficient to indicate it. ‘Those who have 
materials must judge.
