T(/2h' lorality. — "• Revelstoke, B. C." Collected by John Macoun: 

 type in the herbarium of the Geological Survey of Canada (sheet 

 no. 11241). 



Only the type specimen seen. 



This is veiT closely related to A. umbrineUa., having the same indu- 

 ment and somewhat similar heads but more spatulate leaves. It is also 

 closely related to A. meJhi^ the only very striking dili'erence being 

 that its leaves are more dilated terminally. 



8. Antennaria tomentella sp. nov. 



Cespitose, about 1 dm. high, with slender stems and procumbent, 

 somewhat flexible stolons; leaves oblanceolate, acute, prominently 

 uuicronate, 16-2() nmi. long, tomentose or canescent beneath, sparsely 

 so above, the indument more or less persistent; cauline leaves linear, 

 acute to acuminate; heads 4-6, glomerate; involucres 5-6 mm. high; 

 bracts (pistillate) in 2-3 series, nearly all obtuse, the tips greenish 

 brown, oval in the outer to oblong or linear-oblong in the inner. Male 

 plant unknown. 



TijjJc locality. — Near Stevens Pass, Cascade Mountains, Washington. 

 Collected by Sandberg and Leiberg, no. 751; type in the United States 

 National Herbarium. 



The leaves of this plant are noticeably larger than in related species, 

 and the ver}^ light indument of the upper surface is quite characteristic.

A. mucnmaia E. Xelson, Bot. (xaz. 27:209.1899.' 



Ten to 15 cm. high; stolons 4 cm. long or less; leaves narrowly 

 spatulate-oblanceolate, acute or abruptl}^ acute and mucronate, 15-25 

 mm. long, canescent on both surfaces, rarel}' tomentose; involucres 

 5-6 mm. high; tips of the bracts (pistillate) oblong or oblong-lanceolate,

Wyoming and Montana to Oregon (Coville and Leiberg, no. 431.) 

 This species is nearer to the European A. al piaa than any other 

 West American Antennaria. It is very difficult to separate from A. 

 media. It is, however, a much larger plant, with larger heads and 

 leaves which are canescent rather than tomentose. The two species 

 apparently intergrade, and it is probable that A. media can not be
