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.

The Hopi Indians may use Eremogone eastwoodiae as an emetic (B. Maguire 1960).
The nectaries in Eremogone eastwoodiae are different from those of most other species of the genus in North America since they are a separate bilobed structure adjacent to, but not a direct enlargement of, the filament bases opposite the sepals.
