served eminence, while others not less eminent con* 

 sider them " totally distinct." Both plants are familiar 

 to me, and I cannot hesitate to rank myself with those 

 who are of the latter opinion. S. prostrata is the larger 

 species, sending up from its prostrate stem straight simple 

 branches, a foot or more in length, which are clothed with 

 alternate leaves, rather more than an inch long, and one- 

 half as broad. S. repens, on the contrary, is a much 

 branched creeping shrub, whose numerous branches scarce- 

 ly rise above the grass. The leaves are more closely set, 

 of a lighter green, and rarely one half so large. A gene- 

 ral dissimilarity in habit should surely keep plants sepa- 

 rate, though they may agree in some minute characters. 



9. S. dnerea, stem erect ; lower leaves entire, upper serrated, 

 obovate-lanceolate, glaucous, downy, and reticulated with veins 

 beneath ; stipulas half heart-shaped, serrated ; germen silky, its 

 stalk half as long as the lanceolate scales Grey Sallow. 



Hab. Moist woods and hedges. Road-side below Letham- 

 shank, about two miles from Berwick. Allerton-mill 

 dean. April. 



A large shrub very much branched, the branches short, 

 crooked, smooth, or downy. When cut over, it throws 

 up straight shoots, with larger leaves and fewer catkins. 

 These in general are very numerous, an inch long, coming 

 before the leaves. 



10. S. aurita 9 branches trailing ; leaves somewhat serrated, 

 convex, obovate, obtuse, with a small hooked point, hairy, and 

 reticulated with veins on both sides ; stipulas roundish, convex, 

 toothed ; germen silky, stalked ; stigmas nearly sessile. Round" 

 eared Sallow. 



Hab. Deans frequent. JLongridge dean, plentiful. Coast 

 of Berwickshire in several places. April, May. 



A bushy shrub usually 3 or 4 feet high, of a greyish colour, 

 with short crooked branches. It is a very distinct species, 

 well characterised by the form of the leaves, which, 

 though sometimes very small, vary little in their shape. 

 The dwarf variety, with small leaves, is frequent on moors 

 in this neighbourhood. 



11. S. aquatica, stem and branches erect ; leaves slightly ser- 

 rated, obovate-elliptical, minutely downy, flat, rather glaucous
