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

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

 A. Willows, 1358, based wholly upon a single specimen (in Herb. Hook.) 

 from Kodiak, Barclay, and on p. 31, I. c. it was arranged in a group of 

 American species, " manifestly representing European types " as "be- 

 longing to the type of 8 glauca."

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

 widely from the typical 8. Barclayi in its smooth capsules, longer pedi- 

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

 cordata in the leaves proportionately shorter and broader with some- 

 what the texture oi 8. lucida, the young drying black, more glaucous 

 beneath, especially when old; aments thicker and more densely hirsute 

 (much as in 8. discolor} ; capsules very much larger and drying brown. 

 As indigenous at Fountaindale, this is a straggling shrub, about 6 feet 

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

 where exposed to much sunlight. Some of the plants in the Salicetum 

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

 the whole habit that of 8. discolor."

Leaves ovate, ovate-lanceolate, cordate, glandular-serrate, densely to- 

 mentose. On old stems the leaves are ovate-lanceolate and densely 

 tomentose all over, while on young shoots they are broadly ovate, cor- 

 date, and sometimes smooth late in the season. Low, 2-5 feet. Beach 

 sand, Lake Michigan, Illinois, and northwestward. Petoskey (!); St. 

 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 looks as if 

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

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

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