men remarkably cjefious." His fpecimens accord precifely 

 vrith thofe fent by Dr. Afzclius. The very glaucous leaves, 

 clothed on both fides with fine hairy pubefcence, effentially 

 dillinguiflies this plant from canina, under which fo many 

 diltintt fpecies have been negligently confounded, by moil 

 botanifts, till within a few years pail. The fruit has been 

 obferved by Dr. Swartz to vary fomewhat in form, being 

 occafionally oblong, obovate, or nearly globofe : in a young 

 ftate it is glaucous and blueifh ; always fmooth. Calyx 

 partly pinnate.

 Fruit ovate, briltly as well as the flower-ftalks. Prickles 

 of the ftem hooked. Leaflets ovate, downy on both fides. 

 — Native of woods, hedges, and thickets, in various parts 

 of England, flowering in June and July. Tt is alfo found 

 in Germany and Dauphiny. The Jlem is bulhy, and mode- 

 rately tall. Prickles hooked, generally placed under the in- 

 fertion of each k-af-ftalk, either folitary or in pairs. Leaf- 

 lets five or feven, ovate, acute, with fine double glandular 

 ferratures, of a grey hoary green, denfely clothed on both 

 fides with foft pubefcence, and, when rubbed, exhaling a 

 flight acefcent fragrance, mod like the fmell of R. •villofa, 

 n. 20. Caly* pinnate, in the manner defcribed in the gene- 

 ric character, clothed externally with glandular briftles. 

 Fruit in every itate, more or lefs briltly, though fometimes 

 nearly fmooth, while the JlowerJIa/is are always very briltly ; 

 its colour when ripe is a tawny fcarlet. Petals almolt white 

 towards their bafe, otherwife elegantly rofe-coloured, and a 

 little fragrant. Specimens from Ehrhart and Villars have 

 determined their fynonyms ; though the latter, at leaft, by 

 his defcription, has apparently confounded the true -villofa 

 with our tomentofa. So little were Rofes underftood or con- 

 fidered at one time, that we recollect many grave debates 

 among the Norwich botaniits, about thirty years ago, whe- 

 ther this mofl diltintt fpecies were different or not from the 

 common canina!

 ftalks. Prickles of the ftem fcattered, hooked. Leaflets 

 ovate, pointed, very fmooth, unequally ferrated. — Very 

 common in hedges and thickets in Britain, as well as 

 throughout Europe, flowering in June. Few plants con- 

 tribute fo much to the ornament of the country, for it is 

 certainly the molt elegant of our Rofes ; the fcent of its 

 flowers, and the flavour of its fruit, are both peculiarly 

 grateful. The latter, when mellowed by frolt, affords a 

 molt agreeable conferve, kept in the apothecaries' fliops. 

 The Jlem is often fix or feven feet high, ere£t and ftraggling, 

 with irregularly difperfed, pale brown, broad prickles. Leaf- 

 let* ufually feven, of a dark (Tuning myrtle-like green ; 

 paler, or glaucous in fome degree, underneath ; with nume- 

 rous, (harp, unequal, not glandular, ferratures. Leafjlalks 

 fmooth, armed with a few hooked prickles. F/owerJlalls 

 terminal, naked and very fmooth, often folitary, form-times 

 two, three, or four in a kind of umbel. Calyx downy, 

 fcarcely ever glandular. Fruit oblong-ovate, of a coral red, 

 almoft always quite fmooth.

 ovate, downy beneath, fimply ferrated. Leal-ltalks downy. 

 — Gathered by Jacquin on hills in Auitria. Mr. W. Borrer 

 finds it common in Suflex, flowering in July, and ripening 

 fruit in Oftober. — Its habit and general alpeft are like the 

 canina. The prickles are difperfed, hooked. Leaflets ufually 

 feven. variable in length and roundnefs, fimply, and tole- 

 rably equally, ferrated ; always downy, or finely hairy, be- 

 neath, especially the rib ; fometimes (lightly lo above. They 

 have no fcent, and are thicker, as well as lefs fhining, than 

 thofe of canina. Leafjlalks downy and prickly. Flowers 

 pale pink, fragrant, commonly two or three together, on 

 Jlalks covered with glandular briftles. Fruit in every ftage 

 ovate and fmooth, except now and then a ftraggling brittle 

 or two ; fcarlet when ripe, and (aid not to be diftinguifhable 

 from canina. We have never tailed it. Thejlyles, after 

 flowering, are combined and elongated, as in R. arvenjis. 



42. R. dumetorum. Downy-ltalked Dog Rofe. " Perf. 

 Syn. part 2. feft. 1. 50?" Engl. Bot. t. 2579 — Fruit 

 ovate, fmooth. Flower-ftalks villous, fomewhat briltly, 

 clultered. Prickles of the ftem hooked, rather aggregate. 

 Leaflets ovate, doubly ferrated ; (lightly hairy beneath. 

 Leaf-ftalks very downy. — Gathered by Mr. W. Borrer, in 

 bufhy places in Suffex, flowering in July, and ripening fruit 

 in October. We believe it alfo to have been found in Swit- 

 zerland, near Orbe, by the late Mr. Davall, and there is a 

 Specimen, without name, or any mark, in the Linnaean her- 

 barium. The fynonym of Perfoon was fuggeited by Mr. 

 Borrer, nor have we any further authority for its applica- 

 tion. The habit of ihejhrub is more robult than R. canina, 

 with very ftrong hooked prickles, ufually placed in pairs 

 under each footjlalk, and fometimes three or more together 

 under the lateral branches. It differs alfo from that fpecies 

 in having very downy footjlalks ; leaflets rounder and flatter, 

 doubly ferrated, their ribs and veins hairy beneath ; the 



Jlowerjlalks either villous and briltly, or only villous, with 

 foft, fpreading, permanent hairs ; rarely fmooth. Thefe 

 hairs, and the double ferratures, diftinguiih it from co/lina, 

 with which its downy leaf-ftalks agree. The flowers are 

 (mailer and paler than in either of thofe fpecies. Theflyles 

 accord with canina, not with thofe of co/lina.

 flower-ilalks. Stem and leaf-ftalks prickly. Leaflets ob- 

 long, pointed, fmooth. Panicles many-flowered, downy as 

 well as the calyx Desfontaines found this elegant and fra- 

 grant Rofe growing every where in the hedges of Barbary. 

 It is cultivated by the inhabitants of Tunis, who obtain 

 from its petals, by diitillation, a very fragrant elfential oil ; 

 the fame, if we millake not, which in the Ealt Indies is 

 called Ottar. The fhrub is common in our gardens, and has 

 been fo from Gerarde's time, flowering from July to Oc- 

 tober. The femidouble kind moil ufually occurs. The 

 flenu are long and lax, fmooth, befet with fcattered, Ihort, 



'hooked prickles. Leaves of a light, (lightly glaucous green, 

 efpecially beneath, fmooth, except fome downinefs on their 



footjlalks, and their ribs beneath. Slipulas final], narrow, 

 fringed with glands, and divaricated at the points. Flowers 

 rather fmall, white, exceedingly numerous, in large terminal 



panicles, whofe flalks are (lender, downy, deftitute of 

 prickles or glands, as is likewife the (lender, downy, partly 

 pinnate, calyx. Petals with (lender claws. Fruit fmall, 

 fmooth, orange-coloured — R. mofchata major, Bauh. Hid.
