Eriophyllum mohavense, also known as the Mojave woolly sunflower or the Barstow woolly sunflower,[3] is a rare[4] species of small annual flowering plant in the family Asteraceae, found only (endemic) in the Mojave Desert of California.

[5] Eriophyllum mohavense grows in open loamy, gravelly, or clay soils of the Mojave Desert.

Some populations have been found within the boundaries of Edwards Air Force Base and Joshua Tree National Park.

[4][5][3][6] This is a tiny annual herb forming woolly tufts only 1 to 3 centimeters (0.4-1.2 inches) tall.

[4] It is threatened in almost its entire range, by military activities, grazing, off-road vehicles, and energy development.
