Wildflowers of the Mojave Desert: Chaenactis Fremontii

Flowerheads of chaenactis fremontii mature in stages, from outside to in; they consist of several dozen disc florets, the outer of which are noticeably larger, and less symmetric. The plant is quite common in many regions of the Mojave Desert, found below 4,000 feet elevation, along washes and on alluvial fans. There are two similar species in the same range (chaenactis xantiana, chaenactis stevioides).
