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

Christella 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.

gollark: Would it forgive *randomly* or after N cooperates or what:?
gollark: Yes, I keep doing that.
gollark: Y is opponent moves, X is your moves.
gollark: Anyway, the beeoid incursion protocol *does* work well at making tit-for-tat win, so... great...?
gollark: Oh, I just had a really cool idea; you can *read* strategies too, and mostly they're deterministic, so just check the move sequences you see against every other strategy, guess which one is in use, and.... do... something?
