COLLECTION AND IDENTIFICATION OF ROSES 253 
regarded as such. As Crépin used to point out, sepals which

of the R. coriifolia and R. glauca groups, which usually have them 
erect. Notes as to the general direction of the sepals made at 
the time of gathering, especially if they can be made at an earlier 
and a later date than that of collecting, are useful aids to the 
determination of specimens, which cannot always adequately re- 
present them. 
As stated in the last paragraph, the persistence of the sepals 
is a most important point, which is very little liable to variation. 
In the whole of the subsection Eu-canine, except the R. coriifolia 
and Lt. glauca groups, they all or very nearly all fall before the fruit 
even reflexed and falling early. On account of the importance of

Petals.—Except in size te colour, these present no special 
features, and even those are of secondary importance. Though 
we cannot assert it to be a fact, it is probable that considerable 
variation occurs both in size and colour of the petals in the same 
species. Still, in some white, and in others pink flowers prevail, 
the latter colour becoming deepest in the R. pomifera group. A 
a rule the claws of the petals are yellow, but sometimes they are 
concolorous with the lamina. In some of the subsection Villose, 
more especially in the f. pomifera group, the petals are ciliated 
with glands at the apex, and have also hairy claws, both on the 
edges and backs, but we do not think much specific importance 
should be attached to thi 
they are usually so. Such cohesion may sometimes be noticed in 
the Eu-canine, though it is not characteristic of that subsection.
