Corethrogyne filaginifolia (syn. Lessingia filaginifolia) is a species of flowering plant in the daisy family known by the common names common sandaster and California aster.
The taxonomy of this plant and certain relatives is currently changing; recently the Corethrogynes have been grouped together under the name Lessingia filaginifolia, and then moved back to genus Corethrogyne as a single species with many synonyms.[2]
It is native to western North America from the southwestern corner of Oregon through California to Baja California, where it is a common member of many plant communities, including chaparral and woodlands, forests, scrub, grasslands, and the serpentine soils flora.[3][4]
Corethrogyne filaginifolia is a robust perennial herb or subshrub producing a simple to multibranched stem approaching 1 metre (3.3 ft) in maximum length or height. The densely woolly leaves are several centimeters long and toothed or lobed low on the stem and smaller farther up the stem.[5]
The inflorescence is a single flower head or array of several heads at the tips of stem branches. The head is lined with narrow, pointed, purple-tipped phyllaries which curl back as the head matures. Inside are many purple, lavender, pink, or white ray florets and a center packed with up to 120 tubular yellow disc florets.[5]
The fruit is an achene with a pappus of reddish bristles on top.[5]

Corethrogyne es un género monotípico de plantas herbáceas, perteneciente a la familia Asteraceae.[1] Su única especie Corethrogyne filaginifolia, es nativa de Norteamérica occidental desde el extremo sudoeste de Oregon a través de California hasta Baja California, donde es un miembro común de las comunidades vegetales, entre ellos en el chaparral y los bosques, selvas, matorrales, pastizales y los suelos de serpentina.
Corethrogyne filaginifolia se trata de una hierba perenne robusta o subarbusto que produce un simple tallo ramificado de aproximadamente 1 metro de altura. Las hojas son densamente lanudas de varios centímetros de largo y dentados o lobulados bajo en el tallo y menor más arriba en el tallo.
La inflorescencia tiene una sola cabeza de flor o una matriz de varias cabezas en las puntas de las ramas del tallo. La cabeza está llena de estrechos y puntiagudos filarios, de color púrpura. Dentro hay muchas flores liguladas de color púrpura, lavanda, rosa o blanco y un centro repleto de hasta 120 floretes tubulares en el disco amarillo. El fruto es un aquenio con un vilano de pelos rojizos en la parte superior.
Corethrogyne filaginifolia fue descrita por (Hook. & Arn.) Nutt. y publicado en Transactions of the American Philosophical Society, new series, 7: 290. 1840.[2]
