 Mexico, 17 April, 1885, C. G. Pringle, no. 135 (type, in lib. Gr.) This 

 plant, although distributed as E. Parryi, Gray, differs from that species 

 conspicuously in its far more copious and less glandular pubescence, its 

 more sharply toothed leaves, which are truncate rather than cordate at 

 the base, and in its dense inflorescence, the pedicels in E. Parryi being 

 two to four times as long and the heads relatively few.
