Terminal segments of blades fan-like; blades with a naked rachis (more than 1-2 pinnatid) and divided into distinct pinnae. Rachis dark brown and wiry over 2/3 their lengths.

Management:
Disturbance of surrounding slopes such as ATV trails or timber removal or any activity that results in increased erosion will be detrimental. Avoid changes in moisture conditions at the site. These could result from overstory removal, changes in hydrology (stream alteration or increased erosion for example).

Global Range:
This species is globally widespread in tropical and warm-temperate regions, including Eurasia, Africa, the West Indies, Central America and South America (in Venezuela and Peru). The North American range includes roughly the southern one-third of the U.S., with additional disjunct populations in South Dakota and British Columbia (Flora of North America Editorial Committee 1993). In North America, it is sometimes escaped from cultivation north of its natural range (Lellinger 1985, Gleason and Cronquist 1963). Populations in California may be introduced (Hickman 1993).
