A stunted erect busli, with leaflets naked when mature on the 



upper surface, 



midrib beneath, and 



scarcely at all glandular, the serrations closer and sharper than 

 m all the preceding forms and but sliglitly compound; the 

 flowers solitary, the peduncle and calyx-tube densely aciculate, 

 the sepals simple. 



The only British specimens I have seen well representing this 



variety were gathered in Arran by GrcorgeDon and by Mr. James 

 Ward near Eichmond in Yorkshire. 



Var. LAEVIGATA, Baker. 



Peduncle and calyx-tube quite naked, the latter depresso- 

 globose ; the leaves like those of Sahini in clothing and toothing, 

 the petioles villose and glanduloso-setose, but scarcely at all aci- 

 culate ; the sepals all quite simple and not glandular on the back. 



G-athered by the late Mr. Hailstone near Broughton Spa, "West 

 Yorkshire, and a similar plant by Dr. Moore in Antrim and 



Derry.

forms 



5-6 lines long, slightly curved; the scar f inch deep. Leaflets 

 nearly naked above, thinly hairy and densely glandular beneath, 

 the serration like that of var. Smithii ; the petiole scarcely at 

 all hairy, but densely glanduloso-setose, and furnished with nu- 

 merous unequal aciculi, the larger ones decidedly falcate. Flowers 

 one or more; both peduncle and tube densely aciculate and 

 glanduloso-setose- Largest sepals 8-9 lines long, slightly pinnate. 

 Near the sea, Tamlaghbard, Derry, Dr, Moore ! Eecedes from 

 the type (by its prickles and leaves glandular beneath) towards 

 some of the Ruliginosce, but yet evidently belongs here.

Very near Wilsoni, but the leaves smaller, slightly bairy be-
