Vernacular names
English: Wirelettuce

Stephanomeria is a genus of North American plants also known as wirelettuce,[4] belonging to the dandelion tribe within the sunflower family.[5][6]

Stephanomeria species are used as food plants by the larvae of some Lepidoptera species including Schinia scarletina, which feeds exclusively on the genus.
