Malacothrix (plant)

Malacothrix is a genus of plants in the dandelion tribe within the sunflower family. They are known generally as desert dandelions or desertdandelions. Most are native to western North America although a few have been introduced to South America. Several are found only on offshore islands in the Pacific.

Phylogenetic analysis demonstrates that Malacothrix is not monophyletic. Some of its species are related to Atrichoseris, whereas a second group is more closely related to Anisocoma and Calycoseris.
