Hab. Between Spipen River and the north fork of the Columbia, 

 Washington Territory.— A shrubby plant, about a span high, the 

 crowded branches forming tufts, above thickly beset with the rather 

 rigid, lariciform leaves. These are scarcely an inch long, and the 

 widest less than a line wide, rather obscurely one-nerved, minutely 

 glandular-scabrous, tapering from near the apex to the base, not dis- 

 tinctly petioled. Peduncles single, terminating the branches of the 

 season, an inch or less in length, nearly leafless, glandular. Head 

 4 lines in diameter. Involucre almost simple ; the scales lanceolate, 

 acute, glandular-pubescent, and with narrow scarious margins, nearly 

 equalling the disk. Rays 8-11, oblong, yellow. Achemia oblong- 

 obovate, compressed, silky-villous, about the length of the soft, white 

 pappus.

 riosis ; ligides 15-20; pappo albo. 



Hab. Upper part of the north fork of the Columbia River, in open 

 places.— Plant apparently forming tufts from a somewhat ligneous 

 caudex; the stems a span or more in height, herbaceous, erect, simple, 

 moderately leafy below, the whole plant floccose-woolly. Lower and 

 radical leaves 2 or 3 inches long, including the slender petiole, 2 or 3 

 lines wide towards the apex, soft, not at all rigid, entire, mostly obtuse, 

 obscurely 3-nerved by transmitted light; the uppermost reduced to 

 almost filiform bracts. Heads as large as those of A. {Stenotus) lineari-
