﻿376 Nelson: New Plants from Wyoming 



A. Lyallii has been reported are in the northwest, Yellowstone 

 Park being the most southeastern of the points, while these speci- 

 mens are from the extreme southern part of Wyoming. 



Probably in general appearance, as well as in fruit characters, 

 it is more nearly allied to A. atropurpurea L., though good diag- 

 nostic characters separate it equally well from that. 



Type material, no. 2046, collections of 1896 and no. 3460 of 

 1897, the latter supplying mature fruit. 



Oonopsis Wardi (Gray) Greene. 



Apl 



Of this plant there seem to have been no collections since the 

 type material was secured by Mr. L. F. Ward somewhere in Wy- 

 ming, " probably in the southwestern part." Whether that was 

 the original locality may always remain in doubt, but certain it is 

 that no exact duplicates have yet been secured. 



A 



1895 anc * again in 1896 and in 1897, is probably the nearest ap- 

 proach to it that has been secured. This differs so much that it is 

 not wise to send it out as representative of the type, though speci- 

 mens of it have been distributed under my numbers 1553 and 279-. 

 as A. Fremonti near var. Wardi Gray. Now that Ward's speci- 

 mens have most properly been constituted a species, the Laramie 

 Plains specimens may receive a varietal name and may be char- 

 acterized as follows :* 



Oonopsis Wardi condexsata. 



Perennial from horizontal rootstocks on which are borne nu- 

 merous simple or branched, vertical caudices from the summits o 

 which arise the annual herbaceous stems ; stems spreading, mostl} 

 simple as to their bases, freely and fasciculately branched towar 

 the summit, 1.5-2.5 dm. long, very leafy, especially upwards, 

 leaves glabrous, broadly linear to narrowly oblanceolate, 1 -nerve 

 or often 3-nerved at base, acute, sessile or tapering gradually in o 

 a margined base, 6-12 cm. long : inflorescence of the tufted plan 

 as a whole dense, from rounded to almost flat -topped ; inflorescenc^ 

 of the branchlets a close glomerule of about 3 heads, often over^ 

 topped by the upper leaves : head rayless, 15-2 5 -flowered. 10- 

 mm. high : involucral bracts lanceolate-acuminate, nearlyeqnaj^ 



* The available description of the type is so meager that it seems well to 

 than merely point out the differences of the variety.
