Pentagramma

Pentagramma is a small genus of North American ferns. Until 1990 members of this genus were included in "Pityrogramma", and there has been considerable disagreement regarding the species' taxonomy. In the most recent treatment, six diploid species are recognized.
The distribution of "P. triangularis" (goldback fern) extends from British Columbia through the western United States into Baja California in northwestern Mexico. "Pentagramma maxonii" occurs in New Mexico, Arizona, Sonora, Baja California Sur, California, and Baja California. All other species are restricted to Californian and Baja California.
