130 I,EAFI<ETS. 



outer oblong-lanceolate, the inner lanceolate, all dark-purple 

 except as to the green margins : achenes fusiform, purple, 

 stoutly short-beaked, the pappus long, not very delicate, 

 yellowish-white. 



Strongly marked low glaucous species known only as col- 

 lected by Mr. F. V. Coville, 14 Sept., 1902, "on a slope of 

 firm pumice gravel," in the Crater I,ake National Park, 

 Oregon. 



Agoseris CoviLtEi. Size of the preceding, but caudex 

 mostly simple : leaves linear to lanceolate, acutish, not gland- 

 tipped, glabrous, some entire, others variously somewhat 

 crisped and irregularly toothed : scapes little surpassing the 

 leaves, sparsely curled-hairy throughout : involucre broad, its 

 outer bracts ovate-lanceolate and short, the others gradually 

 narrower, all sparsely curled-hairy on the back, naked or 

 nearly so marginally : flowers large, yellow : mature achenes 

 unknown, but without doubt short-beaked. 



Collected by Mr. Coville at the same place and date as the 

 foregoing, this one in full flower, the other in fruit only ; the 

 two species notably dissimilar. 



Agosbris decumbens. Low perennial with depressed 

 leaves and decumbent scapes resting on a simple taproot with- 

 out definite intermediary caudex: leaves glaucous, entire, 

 linear but above the middle tapering to a long acute apex, 

 glabrous except as showing a few long loose marginal hairs 

 near the base : scapes stoutish, not notably striate, the longest 

 4 or 5 inches long, loosely hairy at base and to above the mid- 

 dle : involucres % inch high, glabrous, the bracts in about 3 

 series, all lanceolate, the inner series not narrower than the 

 outer, those of no series acute, not yet notably obtuse : achenes 

 whitish, narrowly fusiform, with distinct but very short white 

 beak, this supporting a copious firm shining-white pappus 

 that is longer than the achene as a whole.
