BAKER ON BRITISH ROSES. 95 



beneath, the terminal leaflet ovate, narrowed or somewhat rounded at the 

 base, the serratures numerous, sharp, simple, and connivent, the petioles 

 villose, but only slightly setose, furnished with three or four hooked aciculi. 

 Stipules and bracts slightly hairy on the back, a little setoso-ciliated. 

 Peduncles naked. Calyx tube and fruit broadly elliptical or subglobose, 

 the sepals leaf-pointed and fully pinnate, hairy on the back towards the 

 edges, slightly setoso-ciliated. Fruit as in the preceding. Styles hairy. 

 This and the two preceding appear to be much the commonest British 

 CanincR, and to be quite identical in the nature of the fruit and duration 

 of the sepals. A closely allied plant from Naunby bank, and hedges at 

 Sowerby, near Thirsk, with slightly double serrations, peduncle a little 

 aciculate, sepals not fully reflexed and a little glandular on the back, is 

 referred doubtfully by Desegiise to U. platyphylloides, Rlpart. 



4. R. platyphyUa, Ban. Habit of growth and prickles of the nonnal 

 plant. Leaves flat, grey-green, glabrous on the upper surface, glaucous 

 beneath and hairy upon the ribs, firm in texture, the serrations moderately 

 sharp and connivent, somewhat unequal but not truly double, the terminal 

 leaflet varying from ovate rounded at the base, to broadly obovate, in fine 

 specimens measuring two inches long by an inch and a half broad, the 

 petioles densely villose, but hardly setose, furnished with several hooked 

 prickles. Stipules and bracts slightly hairy on the back and a little setoso- 

 ciliated. Peduncles naked. Calyx tube and fruit broadly ovate or sub- 

 globose, the sepals leaf-pointed and fully pinnate, pubescent on the back, 

 but hardly at all gland-ciliated, reflexed after the petals fall. Styles villose. 

 The ripe fruit I have not seen on British specimens. Giggleswick and 

 Settle, West Yorkshire. 



(C) Leaves more or less laairy on botli sides. 



5. Pi, uncinella, Bess. Habit of growth and prickles of the normal 

 plant. Leaves flat, grey-green, slightly hairy on the upper surface when 

 young, but glabrous when mature, greyer still and hairy all over beneath, 

 so that the edge is ciliated, firm in texture, the serrations simple, spread- 

 ing and open, as broad as they are deep, callous at the tips, the terminal 

 leaflet broadly ovate or obovate, much rounded at the base, the petioles 

 villose but hardly at all glandular, furnished usually with two or three 

 hooked prickles. Stipules and bracts slightly hairy on the back, dentate 

 but hardly at all gland-ciliated. Peduncles naked. Calyx tube and fruit 

 large, broadly elliptical or subglobose, the green fruit rather more pliable 

 than in the preceding, the sepals reflexed after the petals fall, leaf-pointed
