A FURTHER SfUDY OP AGOSERIS. 129 



subcylindric, hardly even narrowed at summit, the long firm 

 pappus sessile on the body of the achene. 



Rocky ground at 8000 feet on Mt. Rainier, Washington, 

 C. V. Piper, 1895 ; his n. 2149 as in my herbarium. 



Agoseris angustissima. Tufted perennial, with numerous 

 upright slender scapes about a foot high, and the narrowest of 

 leaves about half as long, either upright or ascending, not 

 depressed ; the whole plant pale and glaucescent : leaves very 

 narrowly linear, attenuate-acute, glabrous above, but basally 

 crinite-ciliate, the whole leaf commonly quite entire, yet very 

 often showing one or more pairs of narrow subfalcate lobes or 

 segments an inch long or less : peduncles lanulose under the 

 involucre, the woolliness extending up along the margins 

 of the bracts, these lance-linear and elongated, not even the 

 outer series much wider than the inner, but only shorter : 

 flowers few in the head, apparently rose-red : achenes con- 

 similar, slenderly fusiform, much exceeded by the slender 

 beak, the very delicate and fragile pappus still longer. 



Fir glades, bordering the eastern shore of Diamond Lake, 

 extreme southeastern Oregon, collected by Coville and Apple- 

 gate, 6 August, 1897; also by the same collectors, on 17 

 August in the same year, shore of lake south of the Three 

 Sisters, in the Cascade Mountains ; copious and fine specimens 

 in U. S. Herb. The plant has been taken by some one for 

 A. aurantiaca, and the specimens are so labelled, but the 

 nearest affinity is A. gracilens, a name which better befits this 

 plant than it does the real thing that is so named. 



Agoseris vulcanica. Stout, low, the upright scapes and 

 ascending foliage from a branching caudex, the scapes not 

 greatly surpassing the leaves and 6 inches high or less : leaves 

 glabrous, oblong-linear, rather blunt at apex, though tipped 

 with a gland-like mucro, mostly entire, some with an obscure 

 tooth or two on either margin : flowers unknown : scapes 

 sparingly hairy above the middle, densely so under the head, 

 the bracts wooUy-ciliate, otherwise glabrous or nearly so, the
