The leaflets are covered in a thick waxy epidermis with strong water-repellent properties (the Greek translation of Adiantum means unmoistened). The maidenhair ferns have been used as ingredients of medicinal shampoo, and also as hair restorer. In the sixteenth century they were also used to relieve asthma, snake bites, coughs, and as a stimulant. 

The southern maidenhair fern tends to be found on shady, moist slopes with calcium-rich soil in the Southeastern and Gulf states and the Rockies as far north as Utah and west to California. Northern maidenhair fern occurs most abundantly in Virginia, though scattered collections are known from other coastal areas, as well as from woodlands within North and South Carolina and Georgia, and as far north as Ontario. Western maidenhair is also known as five finger maidenhair, due to the appearance of the leaves at the ends of the stalks, and it is native to western North America. Species of maidenhair ferns can also be found in Europe, around the Mediterranean and in Japan. 

The maidenhair tree or ginkgo Ginkgo biloba) is said to be named after this group of ferns because of the similarity of leaf shape. However, the ginkgo is a conifer tree, and is not related to the maidenhair ferns. 

Tall plants with blue-green, femlike foliage and loosely fluffy clusters of lavender or yellow flowers, meadow rues range from 1 to over 5 tall. Columbine meadow rue Thalictrum aquilegifolium) has leaves resembling columbine foliage other species leaves look like those of maidenhair ferns. 

The solvents commonly used were diethyl ether, benzene (not then recognised as a carcinogen), ethyl alcohol and acetone. Once the staff numbered four or five, a set-up to distil-off solvent from the collected reaction solutions ran every day so that the solid residues could be returned to Johnson Matthey for recovery. Chatt s first secretary still has a vivid recollection of the numerous fires that occurred (about once a month) but fortunately these were always put out before serious damage was done. On one occasion, when Chatt was bringing a distinguished visitor from the house to the lab., he noticed from a distance that a thick cloud of black smoke was pouring out of the fume-cupboard chimney and took the visitor to the arboretum to see an outstanding example of a maidenhair fern instead.
