Discussion

Varieties 2 (2 in the flora).

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.
