| Cyrtomium falcatum|
(L.f.) C. Presl
Cyrtomium falcatum is a species of fern known by the common name Japanese holly fern. It is native to eastern Asia but it is a popular ornamental plant and has escaped from cultivation on other continents to become established in the wild as an introduced species. It can now be found in much of Europe and North America. This is a perennial plant with a large light brown rhizome. It grows from crevices, coastal cliffs, streambanks, rocky slopes, and other moist, stable areas. This fern has leaves exceeding half a meter in length made up of six to ten pairs of shiny bright green leaflets. Each leathery leaflet has a flat to wavy to slightly toothed margin and a netlike pattern of veining. The underside of each leaflet has sori beneath brown or black indusia.
