b A REVISED AERAXGEMEXT OF BRITISH ROSES 



stout but rarely liooked, leaflets suborbicular, fully glandular-biserrate, 

 hairy on mid-ribs and primary nerves, more or less densely covered 

 with subfoliar glands, peduncles and fruit glandular-aciculate. V.c. 

 15, 80, 82, 89. 



f. Nicliolsonii Crep. (sub i2. involuia). I know this by its 

 description only. Branches densely setigerous, leaflets medium, 

 broadly oval or suborbicular, hairy on midribs and primary nerves, 

 fully glandular-biserrate, peduncles and fruit glandular-setose. V.c. 

 91, 97. 



f. Moorei Baker (sub i?. invohrta). Main prickles stout and 

 curved, leaflets rather small, elliptical, acute. V.c. 96, Derry. 



V. SECTION CANINtE. 

 A. Subsection Eu-Canin.e. 



This Subsection is so large, and contains such diverse species and 

 varieties, that no author has succeeded in giving a comprehensive set 

 of characters which will derine it. Its members are perhaps best 

 defined negatively by the absence of the distinctive features of the 

 other Sections and Subsections. 



1. Primary Group of E. caniiia. 



Prickles uniform, leaflets uni- or biserrate, glabrous or hairy, 

 styles very variable, sometimes resembling those of the Sfylosce in 

 being salient and coalesced, but the stigmas are not in a narrow 

 conical or cylindrical head, sepals reflexed and deciduous, rarely spread- 

 ing and hai'dly ever suberect and subpersistent, always deciduous 

 before the fruit ri2)ens. 



i. Secondary Gtroup of R. lutetiana. 



Leaflets glabrous, without subfoliar glands except sometimes on 

 the midribs, petioles sometimes pubescent but not the midribs. 



A. Subgroup Lutetianae. 



Leaflets simply serrate, not always quite uniformly, but none of 

 the leaflets clearl}' biserrate. 



K. LUTETIANA Lem. Whole plant usually eglandular, except 

 rarely a few on petioles and edges of bracts and stipules, leaflets 

 usually large, typically narrow oval with a rounded base, fruit ovoid 

 often large, styles hispid, but varying from thinly so to villous. V.c. 

 3, 5, 8, 18, 17, 20, 22, 23, 24, 32, 33, 34, 36, 37,'' 38, 40, 45, 55, 62, 

 65, 69, 70, Antrim. 



f. viridis Rouy {B. hifetiana typica). Leaflets green. 



f. nitens Desv. Leaflets shining. Probably common. V.c. 36. 



f. glaucescens Desv. Leaflets glaucous, petioles sometimes a little 

 pubescent. Probably common. V.c. 58. 



t'. fallens (Desegl.). Petioles quite pubescent. Prickles straighter. 

 V.c. 3, 17, 23, 36, 55, 57, 58, 69. 



Var. sph(JBrica (Gren.). Like the type but fruit subglobose or 

 broadly ovoid, sepals sometimes spreading. Rarely the styles are 

 glabrous. V.c. 1 or 2, 3, 14, 17, 22, 23, 32, 36, 50, 57, 58, 64, 80, 

 88, Down, Antrim.
