'''''Adiantum aleuticum''''' ('''Western Maidenhair Fern''') is a species of [[fern]] in the genus ''[[Adiantum]]'', native mainly to western [[North America]] from the [[Aleutian Islands]] of [[Alaska]], south to [[Chihuahua]], and also locally in northeastern North America from [[Newfoundland (island)|Newfoundland]] south to [[Maryland]].
The [[frond]]s grow to 15-110 cm high, and are fan-shaped, light to medium green with dark brown to black stems. It prefers fertile, moist soil in rock crevices near streams, from sea level in the north of its range, up to 3,200 m altitude in the south of its range. It tolerates [[serpentine]] rock well, and is confined to this mineral-rich rock in some areas.
Other common names include Serpentine Maidenhair, Aleutian Maidenhair, and Five-fingered Fern.
==Medicinal Uses==
*[[Frond]] tea is used to strengthen [[mucosal membrane]]s, treat coughs, throat congestion, and respiratory irritation caused by air pollution.
