Wyethia bolanderi is an uncommon species of chaparral plant communities in central California.
Sometimes known as Agnorhiza bolanderi (Flora of North America), I’ve opted to use the name from the Jepson eFlora. This 2013 paper by Drs. Abigail Moore and Lynn Bohs, An ITS phylogeny of Balsamorhiza and Wyethia (Asteraceae: Heliantheae), presents convincing evidence that this species should indeed be placed within Wyethia.
Bolander’s mule-ears stands out from other members of the genus in California by having a combination of a single inflorescence on each flowering stem, glabrous (smooth or hairless) leaves, and a lack of basal leaves; the first two properties are evident in this photograph.
