discovery of Mr. Bebb's that half at least of Andersson's 

 type material corresponds with these later collections and not 

 with the original description and figure. 



By 1891, Mr. Bebb had become convinced of his error in 

 founding a variety of 8. Siichensis on the Donner Pass speci- 

 mens. Referring to them, as well as the collections of Lyall, 

 Hall and Macoun, he states (Bot. Gaz. 16:105-106) that 

 seemingly all these specimens belong "to one species for 

 which 8. pellita Anders, is the oldest name; unless this is 

 found to be anticipated by the still older and very obscure 

 S. Drummondiana Barratt. Furthermore, the very inter- 

 esting question whether this is a mountain form of the coast 

 Sitchensis remains to be demonstrated when we know the 

 staminate aments." So far as known they have not yet been 

 collected. All the specimens I have seen bear foliage only 

 (^ Clear Creek above Empire, Colo., Engelmann; Dalles of 

 the Columbia, Engelmann ; Happy Hollow, No, Colo., Pam- 

 mel No. 219). The following description is drawn from these 

 specimens as I have not yet had opportunity to consult those 

 referred to by Mr. Bebb. 



Shrub ; twigs glabrous, greenish-red to dark red, shining, 

 or the younger covered with a glaucous bloom; buds 2-3 

 lines long; leaves numerous, narrowly oblanceolate (or 

 tapering equally to both ends), acute, or acuminate or the 

 lower obtuse, li-2| inches long, 4-9 lines wide, margin entire 

 or obscurely crenate, revolute, upper surface dull green 

 and thinly pubescent, becoming glabrous, often drying dark, 

 under surface densely and persistently clothed with a short, 

 appressed, silvery tomentum ; stout midrib and slender par- 

 allel nerves conspicuously raised below, depressed and often 

 white above; petioles slender, 2-3 lines long; stipules (only 

 on vigorous shoots) semi-cordate, 2-3 lines long, of same 

 texture as leaves. 



Andersson thus desciibes the fertile anient: fertile aments 

 on short, bractless peduncles, thick, very densely flowered, 

 1 inch long; scales pilose, acute, tawny, dark at apex; cap- 

 sules tomentose, becoming glabrate, ovate-conical, acute, 1 

 line long; pedicel short, twice as long as the nectary ; style 

 elongated, yellowish ; stigmas thick, entire, erect.
