Pentachaeta
Pentachaeta is a genus of the family Asteraceae endemic to California. Of the six species members, at least one, Pentachaeta bellidiflora, is classified as an endangered. The etymology of the genus name derives from Greek penta, meaning five, and chaeta, meaning bristle, referring to the pappus scales of P. aurea. It was formerly included in the genus Chaetopappa, but subsequent taxonomic work has established it as a distinct genus. It is most closely related to Rigiopappus and Tracyina. Pygmydaisy is a common name for Pentachaeta.
