R. coriifolia Fries.

a. Feuille. — Poils simples sur les deux épidermes. Poils glandulifères nuls. Epiderme supérieur recticurviligne, d'une épaisseur de 23-31 μ, à cellules grandes ou très grandes. Épiderme inférieur recticurviligne ou subonduleux, d'une épaisseur de 15-19 μ, à cellules grandes. Stomates d'une longueur de 30-36 μ, plus petits que les cellules environnantes ou au plus égaux à elles. Mésophylle bifacial, d'une épaisseur de 123-146 μ, rarement de 90 μ (variété), comprenant 5-7 assises de cellules, les 2 supérieures transformées en palissades remplissant 1/2-2/3 de l'épaisseur totale. Parenchyme spongieux lacuneux. Faisceaux libéro-ligneux des nervures et du pétiolule munis de fibres péridesmiques ; celles-ci rarement nulles ou à parois minces.

17. Rosa CÆSIA.
R. receptaculis ellipticis, pinnis calycinis raris, aculeis uncinatis subæqualibus; foliolis hirsutis eglandulosis duplicato-serratis. 
Rosa cæsia. Engl. Bot. xxxiii. t. 2367. 
Frutex densus, 5-pedalis. Rami suberecti, fusco-purpurei, glaucitie conspicuâ induti; aculeati ; aculei uncinati, subæquales, plerumque binato-stipulares. Petioli tomentosi, glandulosi, plerumque inermes. Stipulæ lineares, glanduloso-serratæ, tomentosæ; eæ floribus etiam solitariis propiores latiores, et demum foliis deficientibus in bracteas ellipticas acuminatas immutatæ. Foliola 5 vel 7, par superius et foliolum impar ceteris majora, elliptica, venulis subtus prominentibus hirsutis ; pagina inferiore hirsuta et interdum quoque superiore, serraturis glanduloso-serratis. Pedunculi subsolitarii, glabri, bracteis breviores. Receptaculum ellipticum, primo glaucitie indu. tum, dein fuscum, glabrum. Calycis foliola eglandulosa, lanceolata, acuminata, pinnata ; pinnæ raræ, lineares, nunc glanduloso-dentatæ nunc integerrimæ. Flores rubescentes. Styli inclusi; stigmata hemisphærica. Fructus ellipticus : maturi faciem nescio.

At Taynuilt in Mid Lorn, Argyleshire; and in Strath Tay, between Dunkeld and Aberfeldie, Mr. Borrer. Side of Loch Tay, Mr. G. Anderson.
I have endeavoured in the description of R. Borreri to show the differences between that species and the present. R. collina is still nearer in character; and I fear that in the present state of our knowledge I can only point out the few and small pinnæ of the the calyx-leafits as a decided mark of separation ; for the double serratures of the leaflets are sometimes rather ambiguous, and always less strongly marked than those of R. Borreri; and the simple serratures of R. collina, though I believe never strictly compound, are yet frequently so irregular and unequal as to produce something of the same appearance. From R. hibernica R.cæsia is artificially distinguished by the total want of the smaller : scattered aculei. I have never seen this plant in a living state; but Mr. Borrer assures me that the dense mode of growth, glaucous shoots, and hoary blueish gray foliage, contribute to give it an appearance very different from that of any other Rose.
Rosa rubrifolia of Villars, Dauph. iii. 549, seems intermediate between this species and R. nuda. Baron Fr. X. Wulfen, in Römer's Archiv. fur die Botanik, mentions a Rosa glaucescens which in some respects resembles this; while in others it seems to unite better with R. collina.
The Rose with leaflets pubescent on the underside, mentioned by Afzelius in his Tent. de Ros. Suec. as confounded in Sweden with R. canina, is supposed by Sir J. E. Smith in Engl. Bot. to belong to this plant; it seems to me to be decidedly my R.collina ß.
