186 Mr. Woorrs on the British Sj)ecies of Rosa. 



species runs less at the roots tlian the other. This I have not had 

 an opportunity of examining; but the roots of the Sussex plant- 

 appear to extend tlieniselves considerably. The mode of growth 

 is certainly much looser and more diffuse. 



From R. gracilis this species is distinguished by its much 

 smaller size, both in the whole plant and in each part; by its 

 peduncles, almost invariably solitary, and by the total want of 

 the large curved aculei so characteristic of that plant — From 

 R. Salmii by the leafits of the calyx, which in that species are uni- 

 formly divided. No other British Rose can be confounded with it. 



6. Rosa gracilis. 

 R. ebracteata, caulibus setigeris, calycibus simplicibus, foliolis 



duplicato-serratis, utrinque hirsutis, aculeis majoribus fal- 



catis. 

 R. villosa. Engl. Bot. ix. t. 583. (excl. Syn. et Fig. fructus.) 



Frutex 8 — lO-pedalis. Rami vagi, intense fusci, aculeati, setigerique ; aculei majores 

 falcati, subbinato-stipulares ; minores recti, sparsi, setas forma referentes et in has 

 demum sensini transeuntes. Peliuli villosi, glandulosi, aculeis parvis subfalcatis inu- 

 niti. Stipules lineares, acuminatae, glanduloso-serratas, glabriusculae, ese floribus pro- 

 piores latiores, et interdum, foliis deficientibus, in bracteas parvas ovatas acumina- 

 tas iinmutatae. Fuliula 7 vel 9, par superius et foliolum impar ceteris majora, omnia 

 elliptica, duplicato-serrata, utrinque hirsuta, margine glandulosa, quod interdum etiam 

 subtus in nervo, sed nunquam, ut credo, in superficie paginae inferioris accidit. Pe- 

 dunculi 1 — 3, plerunique binati, setis inaequalibus obsiti, hoc qui prior evenit erecto, 

 illo graciliore, longiore, nutante. Receptaciitum globosum, nunc setis pedunculi iustar 

 munitum, nunc totus glaber. Calt/cis foliola triangulari-lanceolata, petala aequantia; 

 rarissime in his conspicitur pinnula fihformis. Flares subcyathiformes, petala ob- 

 cordata, pulcherrime rubescentia, basi alba. Slyli inclusi, stigmatibus hemisph%- 

 ricis. Fructus globosus : maturum non vidi. 



The specimen figured in English Botany was sent by Mr. Robson, 

 probably from tlie vicinity of Darlington; and 1 have received 

 it from the same place under the name of R. villosa. In 1808 I
