 leaves with the largest division at the top. Corolla yellow, 

 with broad lobes, longer than the sepals ; receptacle smooth ; 

 styles bent near the middle, the upper part falling, leaving the

 Flowers few, yellow, |^ in. in diameter ; petals twice as long as 

 the sepals, deeply notched ; divisions and bractlets about equal, 

 lanceolate, acute. This is found in wet places near melting 

 snowbanks at high altitudes. Collected at Bullfrog Lake.
