 This species was first discovered in Arizona, then in Sonora, 

 and now in Guatemala. The Arizona material, from which 

 the original description was drawn, proves to be not at all 

 representative. The Sonoran and Guatemalan specimens are 

 more or less pubescent, with lanceolate (in the Guatemalan 

 specimens very narrowly so) long acuminate leaves with taper- 

 ing base and sharply toothed in the middle, loose almost dif- 

 fuse inflorescence, and corolla more often pink than white.

 Evidently a very variable species in foliage, the leaves vary- 

 ing from lanceolate with attenuate base to very broad ovate 

 with either truncate or cordate base, Heyde & Lux 2,840, 

 from San Felipe, Dapart. Retalhulen, alt. 2,050", April 1892, 

 has the usual glabrous achenes, and is reported as a showy 

 virgate plant 14** high.
