We agree with M. F. Baad (1969) in not formally recognizing varieties within Eremogone fendleri. B. Maguire (1947, 1951) recognized five varieties, defined chiefly on leaf and sepal characteristics. While some specimens can be “matched” to varieties, many appear intermediate between them, forming a continuum of variation.

B. Maguire (1947) noted that Eremogone fendleri is “probably to be found in the states of Sonora and Chihuahua, Mexico”; we have not seen any collections from that area.
