[Wikipedia] Etymology: The Latin specific epithet Pentagramma derives from "five lines" or "stripes" while triangularis derives from "three sided", describing the shape of the fern's broad triangular fronds. (link added by Mary Ann Machi)

[Wikipedia] Native People Medicinal & Decorative Uses: The Indigenous tribes of California would use the goldback fern as an analgesic treatment. The Karuk tribe would use the fern to treat pain related to childbirth, and the Miwok tribe would use the fern as a treatment for toothaches. Additionally, Yurok tribe children would use the fern to create body art with the golden powder.[4] (link added by Mary Ann Machi)
