Chaenactis xantiana, Fleshcolor Pincushion

Fleshcolor Pincushion has white flower heads, all disk florets and without ray florets. The fruit is technically called a cypsela which is often mistaken as an achene. Chaenactis xantianaFleshcolor Pincushion bracts surrounding the floral heads are called phyllaries and you note that they do not surpass the white florets. Sometimes the floral heads are whitish or pinkish. Chaenactis xantianaFleshcolor Pincushion blooms from April through July across its rather large geographic range. The young plants are most without hairs (glabrescent) and completely glabrous at flowering. Chaenactis xantianaFleshcolor Pincushion has green leaves that are somewhat succulent and the lower or basal leaves wither at flowering. The upper leaves as shown here are 0 to 1 times pinnately lobed and the lobes are in 1 to 3 (5) pairs arranged spirally on the flowering stem. Chaenactis xantianaFleshcolor Pincushion prefers elevations between 1,000 to 3,500 feet (300-1066 m) and open loose sandy soils often in burn areas. They also prefer dry and semi-dry shrublands and chaparral plant communities. Chaenactis xantianaFleshcolor Pincushion has basal leaves that wither as the plant matures as shown in the photo. This species is found mostly in the southwestern United States in AZ, CA, NV, OR. Chaenactis xantiana

Etymology:
The genus Chaenactis is derived from the Greek word chaino "to gape" and aktis "a ray"; the references because several species the ray florets are enlarged to a wide-open "gaping ray like mouth". The genus Chaenactis was published in 1836 by Augustin Pyramus de Candolle.

The species epithet "xantiana" is named in honor of John Xantus de Vesey (1825–1894) Hungarian exile and zoologist who collected in California and Baja.
