Barstow woolly sunflower

This is a tiny annual herb forming woolly tufts only 1 to 3 centimeters (0.4-1.2 inches) tall. It is covered with long wooly hairs. There are a few lobed, pointed leaves at the base of the tuft, no more than a centimeter (0.4 inches) long each. The leaves are spoon-shaped, sometimes having 3 pointed teeth near the wider tip. The plant produces cylindrical flower heads just a few millimeters wide, containing usually 3-4 bright yellow disc flowers. The phyllaries (green bracts surrounding the flower head) are concave. The disc florets have ray-like lobes, but there are no true ray flowers. The fruit is an achene about half a centimeter long including a short pappus.

Eriophyllum mohavense grows in open loamy, gravelly, or clay soils of the Mojave Desert. It grows between 1,500 and 3,000 feet (450–900 meters) elevation. It can be found in creosote bush scrub and saltbush scrub plant communities. It has been found in Kramer Hills, Boron, around Harper Dry Lake, Opal Mountain, Cuddleback Lake, and Kramer Junction. Some populations have been found within the boundaries of Edwards Air Force Base and Joshua Tree National Park.
