Description:Genus Description - Rhizome short-creeping, horizontal or ascending, with dark or orange hairs; fronds erect, rarely forming a flat rosette, pinnate to tripinnate, papyraceous to coriaceous; veins free or netted; fronds occasionally holodimorphic (but not in ours), fertile pinnae held erect, rarely horizontally or at an angle; sporangia restricted to the erect, dissected, lowermost pair of pinnae arising from the stipe, just below the sterile part of the blade; sporangia in two rows on ultimate segments of fertile pinnae, suberect, sessile, subglobose to oval; spores tetrahedral-globose, striate with parallel smooth or spiny ridges.
Discussion:Type: Anemia phyllitidis (Linnaeus) Swartz [=Osmunda phyllitidis Linnaeus].
Anemia has about 100 species, mostly of Latin America, ten of Africa, one of southern India. The genus is most abundant in Brazil (70 spp.), with a secondary center in Mexico (20 spp.). The three subgenera are: Anemiorrhiza (calciphiles of the Caribbean basin), and the more widely distributed Coptophyllum and Anemia. Some of the species hybridize freely and frequently.
