Mr. Woops on the British Species of Rosa. 221 
cumstances induce me to believe that Jacquin would have in- 
cluded in his species most, if not all, of those different ap- 
pearances which I have united into mine. "The glandular foot- 
stalk varies in `R. bractescens, R. canina, and other neighbouring 
species; which will justify us in rejecting it from the essential 
character in this instance, though a most diligent search bas not 
succeeded in bringing to light a single instance of glands or setae 
on the peduncle of any variety a native of this country :—once, 
indeed, on one plant | found a few hairs on that of the variety y. 
This last-mentioned variety is certainly a very different plant in. 
appearance from either « or B, and may perhaps be a distinct spe- - 
. cies; but Ihave found myself unable to find any character by which | 
it might be separated; and it besides varies greatly in. itself both 
in habit and in character. The leaflets are sometimes almost as. 
broad, but I believe never as flat, as those of It. Borreri and. R. du- 
metorum ; and the calyx-segments sometimes approach in shape 
and number to those of these plants; the serratures too, though. 
never double, become sometimes exceedingly unequal. At other 
times the long leaflets and equal serratures. might lead one, with- 
out the inflorescence, to refer it to R. systyla. ‘To this variety I 
should refer the Rose which is mentioned by Afzelius as a hairy, 
variety of R. canina, and. quoted by Sir J. E.Smith under R.cesia: 
some further observations on Afzelius’s varieties of R. canina will 
be found in the account of that species. ‘The genie fringe of 
the serratures sometimes passes into hairs. — a zt

fow were open: it was a compact bush, between three and 
four feet high, abounding in flower-buds; and the numerous 
small and very acute leaflets gave ita peculiar appearance.
