In the Southwestern United States: Arizona, California and Nevada each have 2 species of Monoptilon, Utah has 1 species, New Mexico and Texas have 0 species.. All data is approximate and subject to taxonomic changes.
Comments: Although commonly called "Mojave" Desertstar, this species is found in both the Mojave and Sonoran Deserts while its closely related sister commonly known as "Daisy" Desertstar (M. bellidiforme) is found primarily in the Mojave Desert Species.
Both species are difficult to distinguish from each other; technical differences include numbers and shape of bristles in the pappus. Other more recognizable differences such as stem color (reddish-purple in Mojave Desertstar vs yellow-green in Daisy Desertstar) and size (up to 10 inches in Mojave Desertstar vs up to 3 inches in Daisy Desertstar) are too variable for practical applications.
In Southwest Desert Flora also see Daisy Desertstar, Monoptilon bellidiforme.
