more compound sepals, the peduncle typically naked, and the 

 sepals naked on the hack. I have seen it only from four counties in 

 Britain : — Somersetshire, woods at Brean Down {Woods 1) ; York- 

 shire, Richmond {Jas. Ward !) ; Durham, Eavensworth woods (So- 

 hertson !) ; and Northumberland, gathered by myself in two places 

 near Wooller. On the other hand, it closely resembles R. Borreri ; 

 but in that the leaves are only very faintly or not at all glandular 

 below, with the lower half broader, the peduncles aciculate, and 

 the sepals rcflexed and deciduous, I have seen a specimen of the 

 Taurian plant from Steven, and of Lindley's from Lyell, and can- 

 not trace any material difference between these and ours and the 

 Scandinavian, French, and Swiss examples labelled with the names I 

 have quoted. Koch, Ledebour, and Renter agree in uniting it with 

 the common South-European R. sepium, ThuilL, which is smaller 

 in all its parts, with the leaves entirely without hairs and narrowed 

 to both ends, glabrous styles, and slender ovate-urceolate fruit.

Prickles of the main stem decidedly unequal, the main ones as 

 large and as strong as those of the type, but only slightly hooked. 

 Leaflets smaller ; the terminal one 9-12 lines long by three-quar- 

 ters as broad, obovate, with a subdeltoid base ; the upper surface 

 at first slightly hairy, the lower thinly hairy and finely glandular 

 all over. Peduncle naked ; calyx-tube narrowly ovate-urceolate ; 

 the sepals, like those of micrmtthaj lengthened out at the point, 

 but only sparingly pinnate; the styles hairy; the finiit ovate- 

 urceolate, 7-8 lines deep. 



In Britain I have seen this only from Allesley in "Warwickshire, 

 where it was gathered by the Rev. W..T. Bree ; but I have authen- 

 ticated specimens, under the three names I have quoted, from 

 Savoy. Prom the true sepium *, which is very widely diffused 

 throughout the south of Europe, it diflfers by its leaves thinly 



* I gathered in the summer of the present year, on the south slope of Hind 

 Head in Surrey, a plant differing only from the typical sepium by having the 

 leaves very slightly hairy on the petiole and midrib beneath. This should now 

 therefore bj placed as the type of the species, and the other forms described as 



its varieties.
