24 A LIST OP BRITISH ROSES 



petioles, white flowers, glol)Ose fruit, and thinly hispid styles. 

 V.-c. 3, 58, 62. 



[B. canina var. calophylla Rouy, Fl. Fr. vi. p. 296. I have four 

 specimens thus named by Sudre. Two of them, from S. Devon, 

 are very near R. Gabrielis, but with more globose fruit. A third, 

 from Cheshire, I also refer to that species. Dingier labelled it 

 " approaching B. Vaulxiana Mout.," one of the Deseglisei sub- 

 group, probably on the strength of a single glandular seta on one 

 of the peduncles, but remarks that it is very near another Cheshire 

 specimen, also labelled var. calophylla by Sudre, but which Dingier 

 thinks very near B. obtusifolia, as a large stout form. I do not 

 know enough of Eouy's variety to include it, in the face of these 

 contradictory opinions.] 



E. RAMEALis Pug. OX Desegl. Cat. Rais. p. 203. Chiefly recog- 

 nized from B. urbica by its elongate ovoid fruit ; it also has its 

 leaflets glabrous above and unarmed petioles, and is near B. semi- 

 glabra except in fruit. My only gathering is confirmed by both 

 Sudre and Dingier. V.-c. 58. 



[B. corymbifera Borkh. in Vers. Forstbot. Beschreib. p. 319. 

 This must certainly disappear from our list. The S. Wilts speci- 

 men mentioned in E. p. 79, is B. stylosa Desv., and that from 

 Plymouth is B. leucochroa Desv.] 



R. JACTATA Desegl. in Journ. Bot. 1874, p. 169. This and the 

 two next species are distinguished from the foregoing ones by 

 their leaflets being irregularly serrate. It is usually a large coarse 

 plant, with rather thinly hairy leaflets, thinly hispid styles, and 

 largish ovoid fruit. The more decidedly biserrate forms are not 

 easily distinguished from B. hemitricha, and the subsimply serrate 

 ones are near B. trichoneura. V.-c. 17, 31, 32, 58. 



R. spiNETORUM Desegl. & Ozan. in Bull. Soc. Dauph. p. 331. 

 A specimen from Minehead, S. Somerset, with unarmed flowering- 

 branches, very large almost biserrate leaflets, very thinly hairy on 

 midribs only beneath, globose fruit and very hispid styles, agrees 

 with Rouy's key, and the name has been confirmed by Sudre. It 

 seems distinct, but I know nothing more of the species. V.-c. 5. 



[B. canina var. squairosoides Rouy, Fl. Fr. vi. p. 295. Two 

 Surrey specimens are referred here by Sudre. I cannot see how 

 they difter from B. jactata. The leaflets should be a little more 

 hairy beneath than in that species, but my specimens are not so.] 



[B. hispichda Rip. ex Desegl. Cat. Rais. p. 217. This name has 

 been given by Dingier to a specimen from Hunts (Ley). It has 

 some of its leaflets with a slightly hairy midrib, some glabrous, 

 and longish ellipsoid fruit. Sudre could not see the hairs on the 

 midribs, so named it B. separabilis. B. hispidula seems far too 

 unsatisfactory a name to retain, see E. p. 76. The specimen fits 

 fairly well under B. semiglabra.] 



SUBGROUP CANESCENTES. 

 These have biserrate leaflets, hairy at least on midribs beneath, 

 and smooth peduncles.
