12 A LIST OF BRITISH ROSES 



R. NEMOPHiLA Desegl. & Ozan. in Bull. Soc. Dauph. no. 3283. 

 Medium leaflets, rounded or not much narrowed at the base, and 

 acute, or at any rate not very acuminate apex, styles always in a 

 projecting fascicle like those of a Stijlosa, and usually glabrous or 

 only thinly hispid, mark this species. The disc is said to be 

 very conical, but this is not always the case, and the fruit appears 

 to be more often globose than ovoid. V.-c. 3, 14, 17, 31 ?. 



R. FLExiBiLis Desegl. Cat. Rais. p. 148. This has medium 

 leaflets, which in typical forms are rounded or shortly acuminate 

 at the apex and narrowed at the base, though often they are just 

 as those of B. sejMvabiUs, also ovoid fruit, glabrous styles, and 

 white flowers. It runs very near B. separabilis, and without a 

 knowledge of the colour of the flowers Sudre is sometimes doubt- 

 ful which it is. V.-c. 3, 13 '?, 14 ?, 17, 36, 62. 



Leaflets Small. 



R. SENTicosA Ach. in Kongl. Vetensk. Akad. Handl. p. 91. I 

 can add but little to my remarks in E. p. 30, but am inclined to 

 agree with Dingier that we have this species or something very 

 near it in Britain. Its small leaflets, rounded at the base, usually 

 villous petioles, and ovoid fruit, seem to be the best points by 

 which it can be distinguished from B. aciphyUa, but possibly it 

 would be more satisfactory to unite them. I think it is frequent, 

 and I have it from v.-c. 16, 17, 22, 34, 35, 36, 58, 62. 



[B. aciphylla Rau. Enum. Ros. p. 69. Sudre uses this name 

 pretty freely ; I have ten gatherings so named by him, three of 

 which Dingier refers to B. spharica, though they seem to me 

 much too small-leaved, two to B. senticosa, one to B. mucronulata, 

 and one between B. senticosa and B. aciphylla, while three he has 

 not seen. I think most of these are better placed under B. senti- 

 cosa, from which B. aciphylla differs in narrower leaflets, more 

 like those of B. agrestis, and more globose fruit. Crepin says 

 specimens of Rau's ow^n gathering are biserrate, and the descrip- 

 tion says " irregularly serrate." If this is so, none. of my speci- 

 mens are correctly named, and continental botanists have got a 

 wrong idea of the species. B. oxyphylla Rip. (Desegl. Cat. Rais. 

 p. 147) is very near B. aciphylki, but with ovoid fruit and quite 

 simply serrate leaflets. Specimens from Cheshire and Surrey 

 may be correctly referred to it, but the name has not been 

 confirmed. I have put all my other gatherings provisionally into 

 the B. senticosa cover.] 



R. MUCRONULATA Desegl. in God. Fl. Jur. Suppl p. 71. This 

 differs from B. senticosa mainly in its glabrous styles. Its 

 leaflets are perhaps a little broader and more cuspidate. It 

 appears rare, but I have specimens which I think may be referred 

 here from v.-c. 15, 17, 36, 58, 65. The Thirsk specimen (E. p. 35) 

 I think comes better under B. senticosa. 



R. Amansii Desegl. & Rip. in Journ. Bot. 1874, p. 169. This 

 may be regarded as a white-flowered, globose-fruited form of
