Acamptopappus shockleyi, or Shockley's goldenhead, is a perennial subshrub in the family Asteraceae found in and near the eastern Mojave desert in southern Nevada and southeastern California. [1] [2] [3]
Acamptopappus shockleyi is a perennial subshrub. Flower heads are borne singly, with both ray flowers and disk flowers, compared to Acamptopappus sphaerocephalus which also grows in the Mojave desert but has only disc flowers on heads in corymbose arrays. [2] [4] [5]
Acamptopappus shockleyi grows from 3,000 to 6,200 feet (910 to 1,890 m) in flats and washes of the eastern Mojave Desert, White Mountains, Inyo Mountains, and areas of southern Nevada. [2]
The species is named after William Hillman Shockley.

The flora of the U.S. Sierra Nevada alpine zone is characterized by small, low growing, cushion and mat forming plants that can survive the harsh conditions in the high-altitude alpine zone above the timber line.

But it is found above the subalpine forest, which is the highest in a succession of recognized vegetation types at increasing elevations.
