''Adiantum'' (), the maidenhair fern, is a genus of about 250 species of ferns in the subfamily Vittarioideae of the family Pteridaceae, though some researchers place it in its own family, Adiantaceae. The genus name comes from Greek, meaning "unwetted", referring to the fronds' ability to shed water without becoming wet.

They are distinctive in appearance, with dark, often black

-rich, moist, well-drained sites, ranging from bottomland soils to vertical rock walls. Many species are especially known for growing on rock walls around waterfalls and water seepage areas. The highest species diversity is in the Andes. Fairly high diversity also occurs in eastern Asia, with nearly 40 species in China. Species native to North America include '' A. pedatum'' (five-fingered fern) and the closely related '' A. aleuticum'', which are distinctive in having a bifurcating frond that radiates pinnae on one side only. The cosmopolitan '' A. capillus-veneris'' (Venus-hair fern) has a native distribution that extends into the eastern continent. '' A. jordanii'' (California Maidenhair) is native to the west coast. There is a rich ''Adiantum'' flora in New Zealand with 3 endemic species (''A. cunninghamii'', ''A. viridescens'' and ''A. fulvum'') in a total of 10 recorded species. Many of these are common especially in the west and south of the islands.

Cladistics

It is now known that this genus is

paraphyletic In taxonomy (general), taxonomy, a group is paraphyletic if it consists of the group's most recent common ancestor, last common ancestor and most of its descendants, excluding a few Monophyly, monophyletic subgroups. The group is said to be pa ...

, and that the vittarioid ferns are derived from this larger paraphyletic genus. However, if '' Adiantum raddianum'', and possibly a few other species, are removed, the remaining plants (genus type: '' Adiantum capillus-veneris'') are then monophyletic.

Cultivation

Many species are grown in the horticultural trade. There are a number of tropical species, including '' A. raddianum'' and '' A. peruvianum''. Both '' A. pedatum'' and '' A. aleuticum'' are hardy to zone 3, and are by far the most cold-hardy members of the genus. ''A. venustum'' is also cold-hardy to zone 5. ''A. capillus-veneris'' is hardy to zone 7. Hybrids, such as ''
