- 190 Mr. Woops on the British Species of Rosa. 
Frutex 6—8-pedalis. Rami vagi, fusci, juniores glaucescentes, aculeati; aculei recti, 
graciles, subæquales, plerumque binato-stipulares.  Petioli tomentosi, glandulosi, 
aculeisque parvis faleatis muniti. Stipulee lineari-lanceolatze, glanduloso-ciliatæ, eæ 
floribus etiam solitariis propiores latiores, et demum foliis deficientibus in bracteas. 
. late ellipticas acuminatas immutate. — Foliola 5, rarius 7, par superius et foliolum 
impar ceteris majora, rhombeo-elliptica, duplicato-serrata, utrinque hirsuta, superne 
mollissima, subtus rugosa, et precipue marginem versus glandulosa, Pedunculi 1, 2, 
setis inæqualibus armati, bracteas superantes. Receptaculum subglobosum, setis for- 
tioribus, sed paucioribus quam quz in pedunculo, munitum. Calycis foliola simplicia, 
triangulari-lanceolata, vix petala longitudine æquantia, glandulosa, setosa; fructüs 
reflexa. Flores concavi, saturate rubentes, rarius albi maculis sanguineis, vel ru- 
bescentes. S/yli inclusi, stigmatibus convexis. Fructus globosus, setosus, ruber.

The specimen in the Linnean Herbarium marked Rosa villosa 
is undoubtedly this species, though the aculei are shorter, stronger, 
and more curved than I have generally observed them. It is 
probable that the plant of our gardens which is generally known 
by that name, and R. tomentosa, were included by Linnzus under 
the same species; but as the existing specimen agrees with the 
description, as far as that defines any one Rose, I have preferred 
assigning the name of R. villosa to this species, instead of retain- 
ing that of R. mollis, given in English Botany. We may be cer- 
tain that Linnæus intended the present plant—that he would 
have included the others is matter of supposition ; and when it is 
found neccssary to subdivide an original species, the Herbarium 
is the best authority to determine which plant shall retain the 
name at first intended to include the whole. In this case a 
further argument arises from the uncertaint y of the plantintended 
under this name by other authors, and our inability to distinguish 
most of them from the numerous varieties of R. tomentosa.
