 Alpine and c&spitose perennial, with fibrous roots. Crowns very 

 short and erect. Root leaves reniform, leathery, with the blade 

 about -I- the petiole, 2.5 cm. wide, 3-cleft to the middle and with 

 the lobes 3-cleft or crenate, these leaves mostly G-8-lobed with all 

 lobes rounded, oval to obovate, smooth, venose. Stems nearly fili- 

 form, decumbent or straggling, with 1-2 leaves near or above the 

 middle, these leaves 3-5-cleft and with sessile to petioled oblanceo- 

 late and obtuse lobes 1-2.5 cm. long. Peduncles ilexuous, filiform, 

 often braeteate in the middle, 2.5-13 cm. long. Flowers Small, 

 yellow. Heads oblong, small. Akenes half-oval, rather sharply 

 ribbed on the edges and a little flattened, with very short beak 

 hooked and not £ the whole. Plant entirely smooth. Petals oblan- 

 ceolate, longer than sepals. This differs from E. Eschscholtzii in 

 the reniform and nearly equally crenate-lobed and leathery leaves 

 with obtuse and not acute tips, and the very short hooKed beak.
