purple in the middle and glabrous except marginally, there 

 somewhat white- woolly : achenes including the short stout beak 

 /^ inch long, the pappus soft, dull white, nearly as long. 



Marysvale, Utah, and Buckskin Mountains, Arizona, at 

 altitudes of 9000 and 10000 feet, Marcus Jones, Aug. & Sept., 

 1894 ; specimens in U. S. Herb. 



Agoseris I.ONGIROSTRIS. Crowu of root simple or branch- 

 ing but fleshy like the root, not subligneous; scapes erect, a 

 foot high ; herbage very pale and glaucous, mainly glabrous : 

 leaves ascending or suberect, 4 to 6 inches long, very narrowly 

 linear, attenuate to a long almost filiform summit, mainly 

 entire, some with a few remote short teeth, others as many 

 short slender lobes, all perfectly glabrous : scapes slender, 

 showing a few long soft hairs almost throughout, but more 

 conspicuously below the middle, terminally under the head 

 scantily white-woolly; involucres an inch high, subcylindric, 

 the bracts very white but showing purple dots, the outer 

 oblong, acute, scantily and even interruptedly woolly-ciliate : 

 achenes long and slender, tapering very gradually to a slender 

 beak (not pappus stipe) of their own length. 



At 9000 feet, near Fish I,ake, Utah, Marcus Jones, 4 Aug., 

 1894, An elegant plant by its almost filiform foliage, remark- 

 able for the length of the beak of the achene, for the plant is 

 of the A. glajica group. 



Agoseris i^ongula. Scapes stout, 2 feet high, but foliage 

 only one-third as long, the whole plant glaucous, also gla- 

 brous as to all the vegetative organs : leaves narrowly linear to 

 lance-linear, acute, often entire, as often with here and there 

 a short salient tooth: involucres many-flowered, 1% inches 

 high, bracts more numerous than in the last, in three series, 

 all triangular-lanceolate, acuminate, the outermost series of 

 about one-third the length of the innermost, the tapering 

 upper part of the middle series more or less distinctly bristly- 

 ciliate : achenes 6 lines long, extremely slender, the beak 

 though slender striated, nearly half as long as the body; pappus 

 fragile .
