It is native to southwestern North America and Central America, from the foothills and deserts of California and Arizona south through Mexico to Costa Rica.[3] It grows in canyons, streambanks, and seeps in several types of habitat. It is found at 50–550 metres (160–1,800 ft) in elevation.[3]
Description
editChristella puberula produces a number of regularly shaped, equally spaced green leaves with numerous long, flat, lance-shaped leaflets. One leaf may exceed 1.5 meters in length, and the thick leaflets may be over 20 centimeters long. The undersides of the leaflets are hairy, especially on the indusia covering the spore-bearing sori.
