Q(3 THE NATURALIST. 



and fully pinnate, tomentose and slightly glandular on the back, hardly 

 at all setoso-ciliated. Styles villose. Banks of the Yore at Aysgarth 

 Force, North West Yorkshire. 



6. E. dumetorum, Thuill. Woods. Habit of growth and prickles of the 

 normal plant. Leaves flat, grey-green, thinly hairy all over above when 

 young, greyer still and hairy all over beneath, thicker and softer in texture 

 than in any of the preceding, the terminal leaflet large, broadly ovate, rounded 

 or often cordate at the base, the serrations simple, open, and neither sharp 

 nor deep, the petioles villose but hardly at all setose or aciculate, stipules 

 and bracts hairy on the back, dentate but hardly at all setoso-ciliated. 

 Peduncles naked. Calyx tube and fruit with us usually large ovate- 

 urceolate, sometimes subglobose, the green fruit more pliable than in the 

 preceding and ripening rather earlier. Sepals fully pinnate and leaf- 

 pointed, reflexed after the petals fall, hairy on the back, but hardly at all 

 gland-ciliated, deciduous before the fruit ripens, which with us is in the 

 latter fortnight of September. Flowers somewhat deeper in colour than 

 in the preceding. Fruit in the large ovate-urceolate form, fully an inch 

 long. Frequent. This is intermediate in appearance and the character 

 of its leaves between R. lutetiana and coriifolla, but as regards the fruit 

 ranges best here. 



7. R. 23ndnosa. R. ccBsia, Borrer in Bri. FL in jjjari not E. B. Stems 

 less arching and prickles more slender than in the normal plant. Leaves 

 flat, glaucous green above, thinly hairy all over when young, glabrous when 

 mature, still more glaucous beneath and hairy all over, the terminal leaflet 

 broadly ovate, roundish or even cordate at the base, the serrations open 

 and furnished with one or two gland-tipped teeth on each side, the petioles 

 villose and copiously setose. Stipules and bracts hairy on the back and 

 setoso-ciliated. Peduncles naked. Calyx tube and fruit subglobose, re- 

 sembling that of the preceding, but the sepals more setoso-ciliated. This 

 is Mr. Eobertson's R. casia, but it differs considerably from Mr. Borrer's 

 Argyleshire plant which was figured under that name in English Botany, 

 and which will be described afterwards. This resembles closely R. dume- 

 torum, differing principally by its glaucous doubly-toothed leaves. Mr. 

 Robertson's specimens which I have seen were gathered by the bridge 

 between Smallwell and Axwell Park, Durham. I have gathered a 

 similar plant on Marrick Moor, North West Yorkshire, and a form 

 with sepals glandular all over on the back, in thickets by the Swale side, 

 near Keld.
