| Hesperocallis undulata A. Gray, 1868 |
Hesperocallis is a genus of flowering plants that includes a single species, Hesperocallis undulata, the desert lily, found in the desert areas of the southwest of North America. A genus (plural genera from Γένος Latin genus "descent family type gender" is a low-level Taxonomic The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group
Hesperocallis has traditionally been classified in Liliaceae but until recently its relationships have been unclear. The Liliaceae, or the lily family, is a family of Monocotyledons in the order Liliales. Other classifications have included it in Hemerocallidaceae or Funkiaceae. Hemerocallidaceae is the Botanical name of a family of Flowering plants. In 1972, Hamilton Traub created the family Hesperocallidaceae with Hesperocallis as the sole included genus. The APG II system includes it in the family Asparagaceae in the order Asparagales in the monocots clade but allows for the optional segregation of Hesperocallidaceae as a monophyletic family when several other families are likewise segregated. Asparagaceae is the Botanical name of a family of Flowering plants. Asparagales is an order of Flowering plants The order must include the family Asparagaceae, but other families included in the order have varied markedly Monocotyledons or monocots are one of two major groups of Flowering plants (angiosperms that are traditionally recognised the other being Dicotyledons Recent molecular systematic studies have confirmed a close relationship with Agave and its inclusion in family Agavaceae has been recommended (Pires et al. Agave is a succulent Plant of a large Botanical Genus of the same name belonging to the family Agavaceae. Agavaceae is a family of Plants that includes many well-known Desert and dry zone types such as the Agave, Yucca, and Joshua 2004).
