Cheilanthes sonorensis Goodding, Muhlenbergia 

 8: 93. 1912. 



Founded upon specimens collected at La Cienaga, 

 Sonora, Mexico, on brushy north slopes, July 18, 1911, 

 by Leslie N. Goodding (No. 942) ; United States National 

 Herbarium, No. 692,686. 



This is precisely Cheilanthes Pringlei Davenp., 

 described from specimens collected by Pringle in the 

 Sierra Tucson, Arizona, May 2, 1883, and beautifully 

 illustrated by Faxon. It is a peculiar plant and a rare 

 one, though since collected in Arizona by Pringle, 

 Parish, Hough, Blumer, and probably by others, and 

 in Sonora and Chihuahua, Mexico, by Hartman, Lloyd, 

 and the late Dr. Edward Palmer. Cheilanthes penin- 

 sularis Maxon is a closely allied species from Lower 



Calif 



ornia.

Founded upon specimens from rocky limestone 

 ridges, Montezuma Canyon, Cochise County, Arizona, 

 collected August 10, 1909, by Leslie N. Goodding 

 (No. 373); U. S. National Herbarium, No. 692,688.

 common state of the species and in the writer's judg- 

 ment does not merit recognition as a distinct species, 

 although several close observers who are familiar with 

 it in the field have repeatedly expressed to the writer 

 a contrary opinion. If recognized as a valid species
