BAKER ON BRITISH ROSES. 21 



doubly-serrated leaves, from Wilsoni and hibernica by the latter character, 

 and from Jiibernica also by its glandular sepals, we have subordinate forms 

 as follows, viz. : — 



1. Sabini, Doniana and gracilis, Angl. ; coronata, Crepin and Renter ; 

 srttai^da, /3 i?rt^;m; peduncles and calyx tubes setose and aciculate, leaves 

 with conspicuously compound teeth, hairy on both sides, more or less 

 glandular beneath. Britain from Clova Mountains and Bi'aemar south- 

 ward to Sussex and Isle of Wight, Belgium, Savoy. 



2. involuta, Smith ; sabauda, Renter ; sabanda, a, Rapin ; peduncles and 

 calyx tubes setose and aciculate, leaves with less compound teeth, glabrous 

 or nearly so above, hairy principally on the ribs beneath, and not- glandular 

 or only slightly so. Scotland, Savoy. 



3. Robertsoni : involuta, Wiyich, Geog. non Smith : peduncles aciculate 

 and setose, calyx tubes nearly smooth, leaves with less compound teeth, 

 nearly glabrous on the upper surface, hairy principally on the ribs beneath 

 and slightly glandular. Northumberland. 



4. subnuda, Crepin; peduncles and calyx tubes smooth, leaves with 

 fully compound teeth, glabrous on the upper surface, very glandular all 

 over beneath, but only a little hairy on the veins. Belgium. 



Judging from the description R. Wilsoni closely resembles Sabini in its 

 habit of growth. The stems are said to be about three feet high in the 

 wild state. In the character of the armature of the stem I do not see 

 any difference between them, and the shape and measurement of the 

 prickles seem to be the same. In size the leaves and leaflets are like those of 

 Sabini. The terminal leaflet on the leaves of the barren stem is usually 

 typically ovate, but varies from cordate to ovate considerably narrowed 

 below. The leaflets are deep green in colour, often blotched with purple, 

 glabrous on the upper surface or very slightly hairy on the midrib, paler 

 beneath, and somewhat hairy or even glandular on the ribs and i^etioles 

 the serrations simple or with only a casual accessory gash, varying from 

 as close as an oi'dinary canina to moderately open. The stipules and 

 bracts are closely setoso-ciliated, the peduncles densely setose and acicu- 

 late, the flowers from one to three in number, the calyx tube either entirely 

 naked or slightly aciculate and setose, the segments about half an inch 

 long in the wild plant, glandular on the back, either simple or slightly 

 pinnate, the point lengthened out and slightly dilated, the petals white 

 but towards the outer edge deeply tinged with rose colour, about five-eighths 

 of an inch broad by three-quarters deep, so that the fully expanded corolla is
