A FURTHER STUDY OF AGOSERIS. 131 



Species most distinct both in habit and character from A. 

 angustissima which is of the same locality. 



Agoseris prionophylla. Size and habit of the last, 

 except that the foliage equals or even surpasses the scapes, 

 the herbage similarly rather arachnoid-hairy : leaves when 

 entire narrowly linear, most of them broader, the margin beset 

 with rather remote broad and short two-fold teeth, or toward 

 the apex smaller but very salient simple teeth : involucre 



little more than % inch high, its bracts broadly lanceolate, 

 those of the outer series and of the middle one appressed-villous 

 on the back and strongly villous-ciliate, the pubescence all 

 straight and fuscous : achenes with short stout beak, and short 

 firm dull-whitish pappus.

Very distinct from the last by its involucres and achenes ; 

 also very peculiar as to the double dentation of the leaves 

 which seem beset with broad short teeth each broadly and 

 deeply notched, as one sees the teeth in the large crosscut saws, 

 so called, of the lumbermen. 



Agoseris Howei.i.ii. I^ow and probably subalpine, the 

 crown of the root often parted but not subligueous ; scapes 

 slender, 4 to 7 inches high, not greatly surpassing the suberect 

 foliage ; herbage deep-green, barely glaucescent, sparsely 

 somewhat cobwebby-hairy : leaves broadly linear, attenuate- 

 acute, entire or with few and remote elongated subfalcate seg- 

 ments ; scapes tomentose under the involucre, this %. inch 

 high, few-flowered and narrow, the bracts all lance-linear, 

 obtusish, the outer series shorter and relatively broader, gla- 

 brous on the back, marginally short-woolly, the inner alto- 

 gether glabrous : achenes nearly cylindric and linear, tapering 

 quite abruptly to a not slender beak longer than the body : 

 pappus not long, dull-white, rather firm.
