Hubbarclston (!); Petoskey (!); frequent along the shores of Little Trav-

 The following notes and description of this interesting species and its 

 varieties have been furnished by Mr. Bebb, who is preparing a Mono- 

 graph on the Salicacece: 



"8. glaucophylla, n. sp. Leaves broadly ovate or elliptical lanceolate, 

 rounded or narrowed at base, apex more or less cuspidate acuminate, 

 coriaceous in texture, glabrous, dark green above except the yellowish 

 midrib, intensely glaucous and obscurely reticulate veined" beneath, 

 the young drying black, margin sharply serrate with glandular inllexed 

 serratures, petioles short downy, stipules ovate, serrate; aments with 

 leaf-like bracts at base, thick, cylindrical, densely flowered appearing 

 with the leaves, when in flower about one inch long; the fertile when 

 mature sometimes very large, 3 inches long, % in. thick; capsules elon- 

 gated-conical from an ovate base 3-5 lines long, glabrous, greenish, 

 turning brown in drying; pedicels 4-5 times the length of the nectary, 

 concealed by the copious long white hairs with which the scales are 

 clothed; style produced; stigmas short thick, entire or 2-lobed. 



"Var. lalifolia. Leaves crowded, broadly ovate-lanceolate, rounded or 

 sub-cordate at base, 3-4 inches long, nearly 2 inches wide, stipules con- 

 spicuous, reniform. Chicago, Babcock, exsicc. No. 3, 4, 13, 15, 47; Mad- 

 ison, Wisconsin, S. II. Watson, in Herb. Canby. Fountaindale (!). 



"Var. angusli/olia. Leaves lanceolate cuspidate, narrowed at base, 3 in. 

 long, % in. wide; stipules small, often wanting; aments elongated- 

 cylindrical. Chicago, Babcock, exsicc. 14, 28, 45, 2%, 8. 



"Var. brevifolia. Leaves obovate, acute, wedge-shaped at base, VA inches 

 long, 5-6 lines wide, prominently reticulate veined; stipules none. 

 Leaves strikingly like those of 8. arbuscula. Sand dunes, Little Trav- 

 erse Bay, Mich.. July 30, '79. C. F. Wheeler. 



"Ten years ago I was inclined to regard this as a robust variety, of 8. 

 cordata, but in a constantly increasing accession of specimens, from the 

 most luxuriant growth down to the starveling of the arid sand dunes 

 of Lake Michigan, it was always clearly recognizable as something dis- 

 tinct from S. cordata. I next tried to find a place for it under & Barclayi 

 Anders., being misled by the author's assertion that & Barclayi Avas 

 very nearly related to 8. cordata, of which it might be regarded as a 

 "quasi modificatio occidentalis robustior," with "shorter and broader 

 leaves" "turning black," etc.; misled, also, by the figure in the Mono- 

 graphia Salicium, which, whatever it may represent, was certainly not
