Deinandra mohavensis (syn. Hemizonia mohavensis) is a species of flowering plant in the aster family known by the common name Mojave tarplant, or Mojave tarweed.
Distribution
The plant is endemic to California. It has a disjunct distribution, occurring in the southernmost Sierra Nevada, the Mojave Desert, the Peninsular Ranges, and possibly the San Bernardino Mountains.[1][2][3] It grows in moister areas in chaparral and riparian zone habitat.[4]
Description
Deinandra mohavensis is an annual herb growing 10-100 centimeters (4-40 inches) tall. The stems are hairy and glandular. The leaves are bristly and glandular and smooth-edged or serrated on the edges.[2]
The flower heads are borne in clusters or somewhat open arrangements. The heads are lined with very glandular phyllaries. Each contains five yellow ray florets, each about half a centimeter long, and six yellow disc florets.[1][2]
Conservation
This plant was considered extinct for over 50 years because its historical populations had disappeared. It was rediscovered in 1994 in the San Jacinto Mountains.[5]
