Nelson : New Plants from Wyoming 381 



mm. long at anthesis, at maturity exceeding the corolla, about 4 

 mm. long : corolla yellow, barely equaling the calyx, lobes short, 

 spreading, rounded, wider than long, about 1 mm. long, vertical 

 appendages very narrow and easily overlooked : style sparsely 

 pubescent, hardly equaling the oval ovary, shorter than the ma- 

 ture ovate capsule ; style branches very short : capsule exceedin_ 

 the calyx at maturity: ovules usually 10, all, or most of them, 

 maturing : seeds brown, irregularly ovate, somewhat angled, sub- 

 acute at both ends, transversely rugose, 2 mm. long, half as wide. 



Frequent in the dry sandy shales near the summits of the 

 white cliffs on Green River. It develops early, being found both 

 in blossom and with mature fruit late in May. The affinities of this 

 plant are with those species of the first division of Dr. Gray's 

 Miltitzia section in his Syn. Fl. N. A.

Emmknanthe salina. 



, Depressed-spreading, 3-5 cm. across, from glabrate to sparsely 

 viscid-pubescent, obscurely glandular; tap-root slender; the 

 wain stem very short and thick, its branches few, short, spreading, 

 not more than 2 cm. high : leaves from oval to oblong, from en- 



re to dentate or pinnately lobed, blade 7-15 mm. long, petiole 

 mostly exceeding the blade : flowers in short few-flowered (3-5, 

 Possibly more) racemes, short-pedicelled or nearly sessile : calyx 

 exceeding the corolla ; sepals linear, about 3 mm. long : corolla 

 yellow, minute, narrow, its lobes short-ovate, about one-third as 

 ' 0n g as the tube: pistil about equaling the corolla; style 



llc k, as long as the oval ovary ; style branches very short, half 

 355 thick as the style : capsule even at maturity shorter than the 

 - x - three times as long as the persistent style : ovules about 8, 

 "°t all maturing : seeds flattened, oblong, sub-acute, light colored, 



mnsversely rugose and obscurely reticulated, 2 mm. long, half as 



This inconspicuous, depressed little plant occurs on Bitter 



reek flats where it makes a scattering growth in the loose, ash- 



,ke alkali soil that occurs at intervals. In this soil soluble salts 



are present in remarkable quantity, often five per cent, or more of 



the whole. .
