L. Wardii forms a dense and strikingly symmetrical rosette 
and is evidently a plant of higher, more exposed localities than 
is utahensis. It also differs from that species, besides in the 
characters elsewhere mentioned, in having the shorter, solitary 
stamens incompletely surrounded at the base by the nectar 
glands. In fruit characters it is quite similar to L. prostrata, 
but unlike that species, has entire, obtuse leaves. 
L. utahensis Rydb. Bull. Torr. Bot. Club 30: 252. 1903; 
B Fl. Rocky Mountains, 333. 1917. 
Perennial, stellate-pubescent throughout, stellae small, rays 
numerous, forked at or near the base, distinct or irregularly 
coherent; stems decumbent or procumbent, 5-20 cm. long, 
unbranched; terminal bud remaining undeveloped; radical 
leaves 2-5 cm. long, blade ovate to oblong, entire, subhastate 
or rarely fiddle-shaped, usually obtuse, narrowed abruptly to 
the slender petiole which usually exceeds the blade in length; 
cauline leaves broadly oblanceolate to spatulate, entire, 5-15 
mm. long; flowers numerous, showy; petals yellow or sometimes 
tinged with red, narrowly spatulate, 7-9 mm. long; filaments
