Hesperocallis

Hesperocallis is a genus of flowering plants that includes a single species, Hesperocallis undulata, known as the desert lily or ajo lily.

It is found in the desert areas of southwestern North America, in Northwestern Mexico, California, and Arizona. The plant grows in Mojave Desert and Sonoran Desert habitats.

Taxonomy
In the APG III system, adopted here, Hesperocallis is placed in the family Asparagaceae, subfamily Agavoideae, since recent molecular systematic studies (Pires et al. 2004) have confirmed a close relationship with Agave. Other classifications have included the species in its own family, Hemerocallidaceae, or placed it in the Hostaceae (Funkiaceae); both families are submerged into the Agavoideae in the APG III system. As with many of the 'lilioid monocots', prior to the use of molecular evidence in classification, it was placed in the Liliaceae.

Uses
The bulbs of the desert lily are eaten by native peoples.
