Lemmoni or H. helenioides; rays well developed; outer bracts 
divided to near base, 9 in number, broad basally, rapidly narrow- 
ing to an obtuse point ; involucre not woolly, except some loose 
pubescence on margins of bracts; inner bracts about as long as 
outer, very broad, with short points, fimbriate; hair of achenes 
and pappus ferruginous, pappus-pales long-awned. According to

referred here is as follows: 
Uraun. — Deep Creek, July 28, 1891, Marcus E. Jones. In 
herb. Mo. Bot. Garden and herb. U. S. Nat. Mus., the two sheets 
exactly similar, Foliage not quite so broad, pale yellowish-green ; 
two stems from one root; outer bracts about eleven, not rapidly 
narrowing. 
Nevapa. — Huntingdon Valley (Elko Co., about 80 miles W. 
of Utah line), 6,000 ft., Aug., 1868, Sereno Watson. In herb. U. 
S. Nat. Mus. About 4 dm. tall; outer bracts deeply divided, not

pappus-scales very long-awned, in some cases not far short of 
length of disc-corollas ; much woolly hair between outer bracts ;

An apparently perennial and xerophytic plant, about 2 dm.

hirsute, similar in type to that of A. Lemmom Greenei, but the 
basal leaves broad-linear and entire ; cauline leaves frequently with 
a couple of lateral lobes. Breadth of leaves or their divisions UP 
to 3mm. Root about 7 mm. broad; stems three, not very stout; 
flower-heads about 17, at various heights (inflorescence not at all 
flat-topped as in the macrantha forms, more spreading than in the 
Lemmon: forms); size of head moderate, 10-13 mm. diam. €X-
