Atriplex CORNUTA. 



No. 5481. June 22, 1894, Green River, Utah, 4500° 

 alt., in clay. 



This has much the habit of A. gracilijlora, annual, 

 branched chiefly below, erect, 6-12' high, very mealy 

 and whitish, stems round; leaves ovate to deltoid with all 

 three angles sharp when deltoid, often cordate, i^ long or 

 less, thick, petioles i" long; pistillate flowers in clusters 

 of 1-3 in the lower axils, in fruit all on pedicels 2-3" long 

 and often pendent; staminate flowers in small, sessile 

 clusters in simple, terminal, leafy racemes, reddish-white; 

 fruit forming a ball 2-3" in diameter by the innumerable 

 horns or corrugated and lobed processes which cover the 

 bracts completely and equal their bract lobes. 



This frequents the same alkaline clayey soil as A . gra- 

 cilijlora . 



Eriogonum aureum. 



No. 6091. September 28, 1894, St. George, Utah, 

 2700"- alt., in sand. 



This is an intricately branched shrub, 1-3° high, widely 

 branched and stout, with rounded top: the stems are 

 rather short, and quite leafy to the base of the short pe- 

 duncle; leaves elliptical, shortly contracted into a petiole 

 2—6" long, the whole leaf being 12—20" long, densely 

 woolly below and much greener above, entire; peduncles 

 1-2-0-' long, then trichotomously and repeatedly branched, 

 not angled, branchlets short; bracts all subulate and 1-2" 

 long, but the upper ones minute; involucres and upper- 

 most divisions appearing glabrous, but really minutely and 

 sparsely woolly; involucres oblong, i" long, divided about 

 }4, the way into rounded, obtuse, erect lobes; flowers 

 golden, i" long, outer lobes oval, obtuse, inner lobes ob- 

 long, with a green midrib, lobes widely spreading; flowers 

 with a nipple-like projection at the base and involucres 

 rounded, not angled; the pedicels are exserted.
