2. Euphorbia inequilatera, Sonder? 



Hab. " This is an Euphoi-bia which I had raised from seeds brought 

 from Sacramento City, California, and named E. suhserrata. Subse- 

 quently it was collected by Dr. Newberry in Ives' Colorado Expe- 

 dition, and it seemed to me to be a form of the variable E. inequilatera. 

 It differs from that plant (at least from the form of it that is common 

 on the western prairies of the Upper Missouri, &c.) in its dentate, in- 

 volucral appendages, and especially by the shorter and comparatively 

 thicker and less undulate seeds, and scarcely serrate leaves. It seems 

 to be almost intermediate between E. petaloides and E. inequilateral
