CLASS XXI1, ORDER I. ] SALIX. 1261 
veins, glaucous, more downy and reticulated beneath, crenated on the 
margin, the footstalk rather short, thick, downy. Stipules rather 
small, rounded, toothed, recurved, and more or less hairy. Catkins 
sessile, erect, becoming elevated on a short leafy branch, and much 
elongated. Scales obovate, sometimes acutely pointed, blackish in 
the upper half, silky. Capsules lanceolate, awl-shaped, with an 
ovate base, downy. Style rather long. Stigmas thick, notched. 
Habitat.—Not rare in Scotland.— Mr. F. Forster. On the Bread- 
albane Mountains ; Heaton Dene, Bunks of the Tyne. 
Small tree ; flowering in May and June. 
Nearly allied to the last species, to which perhaps it ought to be united, 
The germens are more crowded and silky, and the catkins longer, and 
the /eaves rather darker in colour, but we fear not sufficiently constant 
to constitute a good species.
