A LIST OF BRITISH ROSES 13 



B. senticosa, usually with hairy petioles. I have seen a specimen 

 from some British station in Deseglise's herbarium, but it was 

 named with doubt and was hardly in nameable condition. More 

 recently Sudre has so named two Surrey specimens for me, one of 

 which Dingier confirms, but he has not seen the other. Sudre 

 also places here a S. Devon specimen, with very woolly styles, 

 which looks to me much more like B. syntrichostyla, but for its 

 quite uniformly serrate leaflets. V.-c. 3 ?, 17. 



SUBGROUP TRANSITORIiE. 



This subgroup covers all those forms which are not uniformly 

 serrate enough for the Lutetiancs, yet can hardly be classified as 

 biserrate. The biserration is, as a rule, confined to the lower 

 leaves of the flowering shoots, and it may be very slight even 

 there. The subdivision into those with leaflets large, medium, 

 and small is, I fear, just as unsatisfactory as in the Lutetiance, 

 but it is the best I can suggest. 



Leaflets Large. 



R. iNsiGNis Desegl. et Rip. in Mem. Soc. Ac. Maine et Loire, 

 xxvii. p. 112. This is the counterpart of B. lutetiana in this 

 subgroup. Specimens referred to it are sometimes not more 

 irregularly serrate than in B. lutetiana, but its petioles are usually 

 more glandular, its peduncles shorter, and fruit longer, with the 

 sepals often spreading, which causes it sometimes to be mistaken 

 for a member of the Glauca group, especially as its leaflets are 

 very often glaucous. It is, I think, common. V.-c. 3, 17, 24, 31 ?, 

 32, 36, 55 ?, 58, 59. 



R. GLOBULARis Franch. in. Bor. Fl. Centr. Fr. ed. 3, p. 221. 

 Generally similar to the last, but usvially a lower-growing bush, 

 with subgiobose or at least broadly ovoid fruit and broader leaflets. 

 V.-c. 3, 5, 13, 14, 17, 32, 34, 58. 



[B. oleronensis Rouy, Fl. Fr. vi. p. 312. This is the name 

 given by Sudre to a S. Devon specimen. I know the variety only 

 from Rouy's key, where it is credited with glabrous styles and 

 ellipsoid fruit, which my specimen does not present. It seems 

 quite at home under B. spliarica Gren., where I have placed it.] 



Leaflets Medium. 



R. RHYNCHOCARPA Rip. in Desegl. Cat. Rais. p. 162. Charac- 

 terized mainly by the narrow elongate fruit, which is also much 

 narrowed at the apex below the disc. Its styles are usually sub- 

 glabrous. Ripart thought it a form of B. dumalis, but his own 

 specimens being almost uniserrate, it cannot go further than the 

 present subgroup. Its leaflets vary from medium to small. 

 Three of my four gatherings are from Breconshire. V.-c. 17, 42. 



[B. analorja D6s6gl. in Bull. Soc. Bot. Belg. xix. p. 32. Two 

 specimens, one from Cheshire and one from Surrey, have been 

 referred to this by Sudre, the former with much doubt, while tlie
