with any American form, and I am unable to decide what the true S. ful- 

 crata is. In 1808, Andersson described a form from " Ameriac arctica occi- 

 dentah (B. Secmann, lib. Hook.) " the type of ]iis 8. Julcrata a, suhglauca. 

 Fortunately I have a photopjraph and fragments of it (Seemann, no. 178!), 

 m 1849, f.; K.) before me which show that it belongs to S. pukhra. This 

 IS the plant which Bebb (1888) in the explanation of i)late X, figs. 1-7 calls 

 " Secnumn's plant, ' N.W. America,' type of S. phyUcoidcs and afterwards 

 of S./nlcrata" while, as I have just pointed out, it is not the type of either 

 species but oidy of S. fulcrafa suhglauca. In his remarks on this variety 

 Andersson, strange to say, made the following statement (cited already by 

 Bebb) : " Hue forsan etiam pertinet S. phyUcoidcs And., Sal. amer. boreal. 

 1. c. p. 123 " but nevertlieless he gives a full description of the last species 

 on the following page in the Prodromus. 



Coville (1901) accepted Bebb's critical investigation, but he was the 

 first to restore the name S. pulchra of which Bebb ai)i)arently had nq knowl- 

 edge. Coville, however, thought it probable that the type of S. phylicoides 

 came from the American coast instead of from Awatcha Bay, but as I 

 have shown above there is no reason for this. 



S. pulchra ranges, as Coville already said, in Alaska from "the islands of 

 Bering Sea to Point Barrow on the Arctic Coast, to Kodiak Island on the 

 south coast, and to the upper Yukon valley in the interior." In the north 

 I have seen it from as far east as Herschel Island and Dawson in the Yukon 

 Territory, and Lake Bennett in the northwestern corner of British Colum- 

 bia. As already mentioned it may occur as far east as Fort Franklin and 

 Fort Sunpson, but the specimens from these regions are uncertain. Coville 

 also quotes a specimen from the Siberian Coast which I have not yet seen. 



There are a good many specimens which differ from the type by their 

 densely luilry branchlets, and I propose the following variety: "^ 



lb. S. pulchra, var. yukonensis, var. nov. — Atypo nonnisi dilferre vide- 

 tur nuuulis novellis dense griseo- vel fkvescenti-villoso-tomentosis (pilis 

 vix 2" mm. longis), annotinis plerisque etiam satis dense sed interdum tantum 

 partim tomentosis, vetustioribus sacpissime glabris qt nititlulis, ut in typo 

 castancis vel intense purpurascentibus. 



Type Locality: vifinity of Dawson, Yukon Territory.
