A LIST OF BRITISH ROSES 17 



leaflets and fruit should distinguish it ; it is also normally more 

 prickly than the former and has white flowers. Dingier places 

 some of my specimens to B. glaherrima, from which its smaller 

 leaflets, more numerous prickles, and more glandular and hairy 

 petioles distinguish it. V.-c. 17, 58. 



E. STENOCARPA Desegl. in Mem. Soc. Ac. Maine & Loire, xxviii. 

 p. 112. Glabrous-styled like the last, this may be distinguished 

 from it by its narrower leaflets and fruit, which is often quite 

 ellipsoid, and by its rose flowers. It is much commoner than 

 B. Carioti. A Surrey form with leaflets narrower than usual was 

 referred by Dingier to B. canina var. fraxinoides E. Braun. V.-c. 

 3, 17, 23, 31, 32, 36, 58. 



E. BisEERATA Mer. Fl. Par. p. 190. A specimen from Cheshire 

 and one from Salop have been referred to this both by Dingier and 

 Sudre, but the Cheshire specimen departs greatly from the type in 

 its quite ovoid, almost ellipsoid fruit, its long hispid, instead of short 

 villous styles, its much larger leaflets and strongly reflexed sepals, 

 which are, however, much glandular-ciliate. The Salop specimen 

 is much nearer the description in most respects, but is still some- 

 what doubtful. Specimens from the other vice-counties cited 

 have not been seen by either Dingier or Sudre, but belong here, I 

 think. V.-c. 36, 40, 41, 58?, 69. 



[B. canina var. squarrosa Eau, Enum. Eos. p. 77. Though a 

 common variety on the Continent, I have only had this name 

 given to a single specimen, from Surrey. Sudre so names a plant 

 which certainly has more prickles on the flowering branches than 

 usual, and though a few of these are straight, the straight ones 

 are very small, almost like acicles, while the main ones are quite 

 hooked, whereas var. squarrosa should have very numerous, long, 

 straight prickles. My specimen also has subglabrous styles ; they 

 should be villous. I think it is best placed under B. viridicata.] 



Leaflets Small. 



E. adscita Desegl. in Billotia, p. 34. This resembles B. steno- 

 carpa, from which its long hairy styles, on a conical disc, form 

 the best distinction. It usually also has many and stout hooked 

 prickles, smaller leaflets, and white flowers. It seems tolerably 

 frequent in Surrey. V.-c. 13, 17, 40 ?, 58, 65. 



E. SYLVULARUM Eip. OX D6s6gl. Cat. Eais. p. 164. I have two 

 Surrey and one Cheshire specimen placed to this species by both 

 Sudre and Dingier, though they have not much in common in 

 appearance. Small, broadly ovoid or subglobose fruit, with thinly 

 hispid styles, and fully glandular-biserrate leaflets seem to be their 

 common characteristics, the shape of the fruit being tlie liest 

 distinction from B. adscita. By description the prickles should 

 also be straight or sligiitly inclined, but they are unusually strongly 

 liooked in tlie Cheshire specimen (wliich also has densely hispid 

 styles), and quite decidedly curved on those from Sui'rey. I do 

 not know the colour, of their flowers. V.-c. 17, 58?
