can find no certain mention of this Rose except in the
work of Mr. Winch, to whom we are obliged for specimens,
and who found it in several hedges in Durham and Northumberland,
in June 1804. In the very same month Mr. Crowe
and myself noticed it flowering in hedges to the north of
tsury, buftolk, and judged it to be a new species. I was at
first disposed to believe it a variety of R. tomentosa, t. 990,
nor can any botanist be certain that it is not so, because we
really do not know in this genus what constitutes a variety
and what a- species. As the acute botanists of Sweden are
attending to the subject, we trust it will become less obscure.
In the mean while it is our duty as practical observers to collect
facts.
The prickles of the stem in this Rosa are more straight and
slender than in the tomentosa. The leaves are certainly
very different to the touch, nor have they the same scent.
I here is a harshness about them, even when most hairy or
downy, very unlike the tomentosa, neither have they any
greyish hoary hue. Their mid-rib is hairy. The flowers
according to Mr. Winch are always white, tinged or blotched
wuh red, and the fruit large “ in shape rather resembling
that of R. villosa than of tomentosa.” I did not remark
any thing peculiar in the colour of the flowers at Bury, nor
have I seen the fruit, but I observe the germen varies in
shape, and in the quantity of its bristles.
