196 Mr. Woops on the British Species of Rosa. 
I do not find any description to which this Rose can be referred. 
It seems to be called R. villosa by the Scotch botanists; but that - 
name being appropriated to another species, I have given to the 
present plant the name of R. heterophylla, expressive of a charac- 
ter which it usually presents, and which gives to it a certain pecu- 
liarity of habit when compared with any other British species. 
The Roses most nearly allied to this are R. villosa, R. scabrius- 
cula, and R. tomentosa. From the first and last of these a proper 
attention to the leafits of the calyx will distinguish it; and from 
R. scabriuscula, as well as from the two others, the remarkable 
shape frequently occurring in the leaflet, and the narrow bracteæ.

Like the foregoing, this Rose seems to have been unnoticed by 
preceding authors. It is easily discriminated by its crenate 
petals from all other British Roses: but this character it may be 
difficult to determine in the Herbarium, as the petals of Roses 
are apt to fall off, and when preserved generally shrivel very 
much in drying. The shape of the receptacle and the shortness
