R. receptaculis ellipticis, calycibus subsimplicibus, bracteis ellipticis, aculeis rectiusculis subæqualibus, foliolis anguste ellipticis duplicato-serratis.
R. scabriuscula. Engl. Bot. xxvii. t. 1896. Winch Bot. Guide, ii. . Pr. p. 5. 
Frutex 4–6. pedalis. Rami vagi, fusco-olivacei, aculeati; aculei recti, gracilis omnis qui in situ eodem ejusdem fere magnitudinis, plerumque bivato-stipulares, sed sparsi quoque inveniuntur. Petioli tomentosi, glandulosi, aculeisque inininis rectis muniti. Stipulæ lineares, glanduloso-ciliatæ, eæ floribus propiores latiores, et demum foliis deficientibus in bracteas ellipticas acuminatas immutatæ. Foliola 5 rarius 7, par superius et foliolum impar ceteris majora, elliptica, vel potius in meis speciminibus oblongo-elliptica, duplicato-serrata, utrinque hirsuta, mollissima, subtus præcipue marginem versus glandulosa. Pedunculi 1-3, setis debilibus plerumque armati, interdum toti glabri, bracteas longitudine subæquantes. Receptaculum ellipticum, nunc setis aliquot fortioribus quam quæ in pedunculo munitum, nunc glaberrimum. Calycis foliola sub-pinnata, triangulari-lanceolata, petala vix æquantia, glandulosa, fructûs erecta. Flores concavi; petala alba, maculis sanguineis gemmæ persistentibus. Styli inclusi, stigmatibus convexis. Fructus magnus, subglobosus, ruber.

Found by Mr. Winch in hedges in Durham and Northumberland. Engl. Bot. Banks of the Dee, and on the side of Loch Tay, Mr. G. Anderson. Friar's Wood, near Ingleton.
If I were not fortified by the authority of Sir J. E. Smith and of Mr. Borrer, I should hardly venture to describe as a distinct species a plant so nearly approaching to some varieties of R. tomentosa. The calyx-leafits, indeed, though always in some degree pinnate, are never, as far as I have observed, completely fur. nished with offsets on each division as they are in that plant. In this respect it varies exceedingly, approaching however nearer to the compound calyx of R. tomentosa than to the simple one of R. villosa. On this character, such as it is, the specific distinction must principally rest; for the shape of the receptacle and leaflets, though sufficiently distinct in some specimens, still varies so much in this tribe of Roses that I dare not place much reliance on it. Still less can I depend on the greenness and harshness of the pubescence, the characters by which this Rose is more more particularly pointed out in Engl. Bot.; as the specimens which I have received from Mr. Winch, the original discoverer, are hoary with a velvety down, and exceedingly soft on both sides—perhaps even more so than is usual in any other species; and those which I have gathered myself agree with them in this as in every other particular. Mr. Winch also in his Botanist's Guide describes the leaflets as densely covered with down. I have reason to believe that the plants gathered by Sir J. E. Smith near St. Edmund's Bury, which in Engl. Bot. are attributed to this species, rather belong to R. tomentosa v of this essay. The extreme variableness of this latter species (the Rose I have had the most opportunities of examining under different circumstances) induces me however to attach very little importance to this peculiarity in the pubescence.

Rosa scabriuscula Roughish-leaved Dog-rose. [includes colored plate 1896]
We can find not 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 Bury, Suffolk, and judge it to be a new species...
The prickles of the stem in the Rosa are more straight and slender than in the tomentosa. The leaves are certainly very different to the touch....There is a harshness about the, even when most hairy or downy, very unlike the tomentosa, neither have they any greyish hoary hue...The flowers according to Mr. Winch are always white, tinged or blotched with red, and the fruit large "in shape rather resembling the of R. villosa than of tomentosa.
