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 this species is commonly called "Daisy" Desertstar it is found primarily in the Mojave Desert; the closely related "Mojave" Desertstar, (M. bellioides), is found in both the Mojave and Sonoran Deserts.
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.
