Mojave Tarweed

Deinandra mohavensis (D. D. Keck) B. G. Baldwin

Comments

provided by eFloras
Deinandra mohavensis is known from the Peninsular Ranges (San Jacinto Mountains, Palomar Mountains, Anza Bench) and southernmost Sierra Nevada (Short Canyon, Jawbone Canyon region), and San Bernardino Mountains (where possibly extirpated). As noted by A. C. Sanders et al. (1997), D. mohavensis occurs in unusually mesic habitats for Deinandra (somewhat similar to situations where D. arida and D. floribunda occur) and has a highly disjunct distribution. It is in the Center for Plant Conservation’s National Collection of Endangered Plants.

Deinandra mohavensis

provided by wikipedia EN

Deinandra mohavensis, commonly known as Mojave tarplant or Mojave tarweed, is a species of flowering plant in the family Asteraceae.

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.[3][2]

Distribution and habitat

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.[3][2][4] It grows in moist areas in chaparral and riparian zone habitat.[5]

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.[6]
