126 LKAFLETS. 



Type specimens collected by myself on prairies of the Hum- 

 boldt River at Deeth, Nevada, 14 July, 1896. Mr. Heller's 

 9130, from Deeth, in 1908, has oblong-linear rather short 

 foliage, but scapes and heads as in .^. longula, though the 

 bracts of the involucre are wholly naked. The achenes in his 

 specimens are far from mature. 



Agoseris lapathifoua. I^arge and rather coarse peren- 

 nial, with stout scapes 2 feet high, and rather ample foliage 

 of 4 to 8 inches length ; herbage glabrous and greenish, not 

 glaucous but glaucescent only: leaves lanceolate, acute, entire, 

 narrowed very gradually below to a short winged petiolar part 

 not amounting to a petiole ; heads broad and many-flowered, 

 but the involucres barely an inch high, their bracts lanceolate, 

 acute, glabrous, the outer only shorter and more herbaceous 

 than the inner : achenes with stout beak one-third as long as 

 the body; pappus rather firm, scaberulous, much longer than 

 the achene. 



Above Houston, Idaho, L. F. Henderson, 1896 ; his n. 3681 

 as in U. S. Herb ; the broad foliage remarkably green rather 

 than pale and whitish, and quite recalling the foliage of dock. 



Agoseris lacera. Tall and rather slender perennial, the 

 scapes erect from the very base and 2 feet high, the foliage 

 suberect, more than half as high, this and the scapes below 

 the middle clothed thinly with long sordid crisped hairs, but 

 all the herbage very pale as with bloom : leaves linear, long- 

 attenuate at apex, usually entire below the middle, above it cut 

 deeply into a few subulate-linear nearly straight and ascend- 

 ing or suberect segments : heads very small for the plant, the 

 involucres only Yx inch high, its bracts all lance-linear and 

 consimilar, the outer as usual shorter, but in proportion not 

 much broader, all attenuate-acute and villous-ciliate : achenes 

 short and shortly beaked, the whole hardly as long as the fine 

 barbellulate white pappus. 



Pullman, Washington, 28 July, 1899, C. V. Piper, in U. S. 

 Herb., under the collector's n. 3027.
