Hesperocallis is a genus of flowering plants that includes a single species, Hesperocallis undulata, the desert lily or ajo lily, found in the desert areas of the southwest of North America.

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.^[1] 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.^[2] 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 were eaten by native peoples.
