The Identity of Andersson's S.'^lix PELLrrA. — Sa/ix pellita, 

 Anders. Mon. Salix (1865) 139, was based on two plants, one from 

 Lake Winnipeg {Bourgeau), the other from the Rocky Mountains 

 {Lyall). Material of the Lyall plant in the Gray Herbarium is dif- 

 ferent from any eastern species, but is very near the recently described 

 S. subcaerulea, Piper, which occurs from the mountains of Oregon 

 and Northern California to Montana. In August, 1903, the writer 

 examined at Kew original material of the Winnipeg plant of Bour- 

 geau and found it quite unlike the Lyall specimen but exactly a 

 species which abounds along certain rivers of Maine and eastern 

 Canada ; and since the Winnipeg shrub was first cited by Andersson, 

 it, rather than the Rocky Mountain element of his complex species 

 must bear the name, S. pgllita. This species has long perplexed the 

 botanists who are familiar with northern Maine ; and for want of a 

 more satisfactory disposition for the plant, it has been temporarily 

 placed with S. Candida. From that species, however, S. pellita is 

 very quickly separated. ^. Candida, as yet unknown in Maine, is a 

 species primarily of larch or arbor-vitae swamps, the branchlets, 

 leaves (usually above as well as beneath) and capsules pubescent 

 with dull whitish lanate or flocculent tomentum ; and the young styles 

 conspicuously tinged with crimson. S. pellita, a species ordinarily of 

 gravelly or well-drained shores, has the young branchlets glabrous or 

 at most minutely pilose, the leaves glabrous or quickly glabrate 

 above, whitened beneath, at least when young, with lustrous velvety 

 or silky pubescence ; the ovaries and capsule silky-tomcntose ; the 

 styles yellowish or brownish. In northern Maine and adjacent Can- 

 ada S. pellita is one of the commonest willows, and the material now 

 at hand shows it to range from the Dartmouth River, Gaspe 

 County, Quebec, to the lower Androscoggin River, Maine, north to 

 Lake St. John, Quebec, and west to Lake Winnipeg. — M. L. Fer-
