habit, in its much larger serrate leaves, and in its southern range. The 

 varietal name used by Engelmann is already employed in Euphorbia 

 as a specific name, so that it has been necessary to propose a new one. 

 The species is based on material collected at Cape San Lucas by 

 Xantus. I have studied, and the above diagnosis is based upon col- 

 lections made by Palmer (34) at La Paz, Grabendorfer at San Jase 

 del Cabo, and Brandegee at San Felipe; all from the cape region of 

 Baja California.

The species here described is very distinct and appears to have no 

 immediate relatives. Its large oblongish leaves at first glance suggest 

 the species of the section Hypericifoliae, but its real relationships are 

 in the section Chamaesyce. It may possibly be related to E. leuco- 

 phylla, but that species, while resembling it much in structure and 

 disposition of the involucres, as well as in general habit, has smaller 

 rounded ovate leaves with conspicuously dentate margins. The out- 

 standing features of the plant are its large entire brownish subsessile 

 leaves and tomentose young stems. Besides the type, I have seen an 

 identical plant collected at the type locality by Brandegee (535).
