E. Cymbalaria, Pursh. Everywhere in low moist ground, evincing a 

 choice for alkaline soils, but flourishing in the freshest of sno^v- water; 

 altitude, 5-10,000 feet. From Saguache, in San Luis Valley, we have 

 a form with erect, stout scape, bearing three or four flowers, having 

 thicker aud larger leaves, aud manifesting little or no tendency to 

 produce stolons. (101.)

 E. Br., var.,^. Hook. Exactly the plant of Plate \j^ Fl. Bor. Am. (120.) 

 In my specimens the hairy carpels of var. ^ afford by far the most 

 marked distinction from var. cardiophyllus. The akenes in (3 are also 

 larger than in the other variety. 



E. glabeerijMLts, Hook. Leaves rather lanceolate than ovate. Plate v,

E. RECURVATUS, Poir. Style not conspicuously recurved, but in de-

 petals, shape and dentition of scale markedly corresponding with de- 

 scription as given by T. & G. (102.) 



E. Adoneus, Gray. Apex. In original description of this plant, Gray 



refers to it as being strictly alpine. Our specimens from the same 



region were collected at an altitude but little greater than that of 



Denver, which is 5,317 feet above the sea. (118.)
