Mountain Flora 511 



3-5 mm. long, the innermost long-attenuate, unarmed : flowers 

 rose-colored. 



This species is nearest related to C. Flodmanii, differing in the 

 more simple habit, the smaller, thicker, not pinnatifid leaves and 

 shorter and weaker spines. From C altissimus it differs in the 

 denser tomentum, the simple habit, the narrower and fewer bracts 

 and their narrower dorsal ridges.

Agoseris arachnoidea sp. nov. 



Perennial with a tap-root, more or less floccose throughout. 

 Leaves 1.5-2 dm. long, more or less runcinate-lobed, oblanceolate 

 in outline, long-attenuate at the apex, densely floccose when young, 

 more glabratein age : scape 1.5-4 dm. high, densely woolly above, 

 less so below: head 2-2.5 cm - high, 1.5-2 cm. broad: bracts in 

 about 3 series, linear-lanceolate, long-attenuate, the inner one-third 

 longer than the outer : flowers at least in age rose-purple : beak 

 of the achenes fully as long as the body. 



Perhaps nearest related to A. anrantiaca but differing in the 

 larger heads, the dense pubescence and the lighter flowers. It 

 grows in meadows at an altitude of 2000-2800 m.

^ Agoseris pubescens sp. nov. 



Perennial with a tap-root and short branching caudex. Leaves 

 narrowly oblanceolate, about 1 dm. long, .5-1 cm. wide, acuminate, 

 slightly glaucous but even in age villous-pubescent : scape 1.5—2 

 dm. high, sparingly villous: involucre about 2 cm. high and 1.5 

 cm. wide, villous and somewhat viscid : bracts with a dark 

 median line and sometimes tinged with purple, the outer ones 

 ovate-lanceolate, about % the length of the linear-lanceolate 

 long-acuminate inner ones : flowers lemon-yellow, the outer stri- 

 ate or tinged with purple : beaks of the achenes short and striate 

 throughout. 



This species is nearest related to A. glauea and A. scorzonerae- 

 jo.ia but differs in being very pubescent. It grows in moist 

 meadows at an altitude of 2000-2500 m.
