maturity ; segments unequal, the 3 outer oblong-spatulate, often 

 oblique at the base, the 3 inner cuneate-spatulate, slightly longer 

 than the outer : filaments short, villous : achenes 3-angled. 



On mountain slopes at high altitudes, Utah and Nevada. Sum- 

 mer and fall. 



The specimens on which the above species is founded have 

 erroneously been referred to Eriogonum Tolmianum. The stouter 

 habit, the glabrous or almost glabrous foliage, the leathery leaves, 

 the smaller involucres with their linear or oblanceolate segments 

 and the less manifestly stipitate calices with their oblong-spatulate 

 oblique outer segments, prevent it from being merged with E. 

 Tolmianum. We have specimens as follows : 



Nevada: Clover Mountains, September, 1868, altitude 3,000 

 meters. S. Watson, no. 1014. 



Utah : Bear River Canon, August, 1869, altitude 2,900 meters.

</ Eriogonum Covillei. 



Perennial, dwarf, caulescent. Stems branched at the base ; 

 branches forming tufted mats, forking, 2-3 cm. long, usually 

 gnarled : leaves densely crowded at the ends of the branches, spat- 

 ulate, 4-8 mm. long, obtuse or acutish, villous-tomentose or can- 

 escent, sometimes glabrate above ; petioles much shorter than the 

 blades: scapes erect or ascending, 1-4 cm. long, topped by a 2-6- 

 rayed umbel: bracts foliaceous, oblong or linear-oblong: involu- 

 cres turbinate, villous-tomentose ; tube 2 mm. high, slightly en- 

 larged at the base, constricted near the middle; segments 6-10, 

 spreading, linear-oblong, obtuse: calices golden-yellow, glabrous, 

 about 3 mm. long ; segments cuneate or the outer cuneate-obovate, 

 all rounded at the apex or the inner retuse : filaments villous near 

 the base : achenes 3-angled.

Among the many distinct species heretofore grouped under 

 ogonum umbellatum, the present one is a conspicuous example. 

 The dwarf stature and habit debar it from E. umbellatum, while the 

 peculiar villous or canescent tomentum of the foliage is unknown 



in that species.
