Chaenactis glabriuscula, with the common name yellow pincushion, is a species of flowering plant in the daisy family. It is native to California and Baja California. [2]
Chaenactis glabriuscula grows in a wide variety of habitats, such as the Sierra Nevada, the Mojave and Colorado Deserts, and the interior chaparral and woodlands, coastal sage and chaparral, and the montane chaparral and woodlands ecoregions. It is a variable plant, especially across varieties, of which there are many. [3] It is generally found below 7,000 feet (2,100 m) elevation. [4]
In general, Chaenactis glabriuscula is an annual herb producing one or more mainly erect stems approaching 50 cm (20 inches) in maximum height. The branching stems are hairy and often cobwebby with fibers. The leaves are up to about 10 centimeters (4 inches) long, sometimes fleshy, and usually divided into many very small, curling lobes.
The inflorescence produces one to twenty or more flower heads on a very long, erect peduncle. The flower head is lined with flat, hairy or woolly glandular phyllaries 4.5–10 mm (0.18–0.39 in). It contains many tubular flowers in shades of gold to bright yellow, the outermost flowers large and flat-faced, most with protruding anthers. The fruit is an achene which may be over a centimeter long including its layered pappus of scales. [5] [6]
One variety, Chaenactis glabriuscula var. orcuttiana — Orcutt's yellow pincushion, is a rare variety limited to the beaches and coastal dunes of Southern California and Baja, where it is threatened by development of its coastal habitat. [7] Urban locations on the Santa Monica Bay, in the northern Ballona Wetlands near Venice and on the Bell Avenue Sand Dune Park recreation area's dune (~185 plants) in Manhattan Beach, each had var. orcuttiana populations newly discovered in Spring 2010. [8] [9] The variety is listed by the California Native Plant Society as endemic to California dune ecosystems and significantly declining, with confirmed populations in parts of Ventura, Los Angeles and San Diego counties.

It is mostly found in coastal sage scrub and coastal chaparral habitats, but two varieties in Baja California can be found in foothills and deserts. In California, variety californica is regarded as a rare and threatened plant, with a California Native Plant Society listing of 1B.1, in part due to its limited number of occurrences and threats from development. It formerly was considered to have a larger range due to the inclusion of Cylindropuntia bernardina within it as the variety parkeri.
