drawn from the type specimen of 8. Barclayi. This {8. Barclayi) was 

 published as a new species in the author's preliminary Synopsis of n 

 A. Willows, 1858, based wholly upon a single specimen (in Herb, Hook ) 

 irom Ivodiak, Barclay, and on p. 31, 1. c. it was arranged in a group of 

 American species, •« manifestly representing European types'' as "be- 

 longing to the type of & glauca," 

 ********** 

 "It answers my present purpose to .show that & gkxucophylta, n sp differs 

 widely from the typical & Barclayi in its Smooth capsules, longer podi- 

 eels, shorter style, and very different stigmas. It also differs from 8 

 cor data in the leaves proportionately shorter and broader with some- 

 what the texture of S. lucida, the young drying black, more glaucous 

 beneath, especially when old; amen t s thicker and more densely hirsute 

 (much as in 8. discolor); capsules very much larger ami drying brown 

 As indigenous at Fountaindalc, this is a straggling shrub, about 8 feet 

 high, the young twigs glabrous and bright yellow, Btained with crimson 

 where exposed to much sunlight. Some or the plants in theSalicetum 

 however, are more erect, 8 feet high, brownish twigs, puberulent, and 

 the whole habit that of 8. discolor."

 Jo., Dr. Wright in Torr. Herb.— Bebb. Hooker's original specimens 

 came from Labrador. "Well marked by the copious, long, narrow 

 serratures to the leaves tipped with a gland, so that the leaf took 

 it were fringed with pedicellate glands. These leaves are an inch or 

 more long, clothed, even when fully grown, with long silkv tomentum 

 on both sides, etc."— Part of Hooker's original description of specimen
