A REVISED ARRANGEMENT OP RRITTSH ROSES 13 



Yar. fug ax (Gren.). Leaflets l)Lserrate, not subfoliar- glandular 

 peduncles glandidar-liispid, fruit normally subglobose, but more often 

 ovoid or ellipsoid in our forms. V.c. 36?, 58, ^^^ 81, 88, 98, 

 Down ?. 



Var. steplianocarpa (Desegl. k Hip.). Leaflets biserrate, with 

 subfoliar glands on the primary nerves, peduncles smooth, fruit 

 broadly ovoid or subglobose. V.c. 57, 70, 88, Down. 



Var. cenensis R. Kell. As in the last, but peduncles glandular- 

 hispid. The leaflets vary much in size and shape in our forms. 

 V.c. 40, 57 ?, 70, 88. 



B. Subgroup Subcaninse. 



I define this Subgroup as having the characters of the Group of 

 jB. jReuferi, but with the sepals not rising above the disc, and often 

 quite rettexed and deciduous, but this is neither Crepin's nor Keller's 

 definition. The former credits it with hairy nerves, which would 

 include it in the Siobcoriifolia Subgroup, while Keller describes it as 

 a series of varieties much nearer the R. canina Group than that of 

 M. JReuteri. The absence of the most conspicuous feature of the 

 Group makes its varieties diflicult to recognise. 



a. Reuteri var. siihglauca W.-Dod. Like R. Reuteri, i. e., leaf- 

 lets simply serrate, peduncles smooth, fruit ovoid, but sepals reflexed. 

 V.c. 13 ?, 23 ?, 40, 69, 78 ?, 79 ?, 88. 



Var. montivaga (Desegl.). Leaflets irregularly serrate, fruit 

 subglobose. Though described as a Canina form, both description 

 and specimens clearly indicate a variety of R. Reuteri. V.c. 36, 

 57, 60. 



Var. denficulafa R. Kell. This includes all the forms with bi- 

 serrate leaflets, the other characters being variable. It therefore 

 probably requires subdivision. V.c. 34, 58, 70, 88. 



C. Subgroup Coriifolise. 



The counterpart of the Subgroup Reuteri, with more or less hairy 

 leaflets, at least on the mid-ribs. Its prickles are rarely stout, 

 usually rather small but hooked, though sometimes long, rather 

 slender, and curved. 



R. Reuteri var. coriifolia (Fr.). Leaflets variable in size, 

 simply serrate, hairy on both sides, or at least on the lower surface, 

 Avithout subfoliar glands, fruit subglobose. V.c. 39, 57 ?, 58, 62, 

 65, 69 ?, 70, 80, 88, Down. 



f. subhiserrata Borb. (sub R. coriifolia') has its leaflets irregu- 

 larly serrate or slightly biserrate. V.c. 3 ?, 38, 39, 57, 58, 92. 



Var. implexa (Gren.). Leaflets often irregularly serrate, thinly 

 hairy, often on mid-ribs only, without subfoliar glands, though Grenier 

 has named examples with them on the primar}^ nerves, sepals often 

 less erect, connecting it with var. sithcollina. V.c. 57, 58, 65, 88. 



Var. Baker i (Desegl.). Somewhat ill-defined both by Baker and 

 Deseglise. Leaflets fully biserrate, rather densely hairy, often with 

 a few subfoliar glands, typically narrowed at the base, but not 

 always so, peduncles smooth or a little glandular-hispid, fruit ovoid, 

 ellipsoid, or urceolate, smooth. V.c. 43, 62, 67, 69 ?, 70 ?, 8S.
