Leymus and Cyrtomium, are native to which mutual location?
Cyrtomium Cyrtomium is a genus of about 15-20 species of ferns in the family Dryopteridaceae, native to Asia, Africa (including Madagascar), and the Pacific Ocean islands (Hawaii). It is very closely related to the genus "Polystichum", with recent research suggesting it should be included within it (Little & Barrington).
Enemion Enemion (false rue-anemone) are spring ephemerals with white flowers, branching stems, and finely divided leaves in the buttercup family. One species, "Enemion biternatum", is native to eastern and central North America, while "Enemion occidentale", "stipitatum", "hallii", and "savilei" are native to the West Coast of the United States and Canada. The genus "Isopyrum" is similar, and has species native to Europe and Asia.
