Adiantum pedatum L.
Northern maidenhair fern
Northern maidenhair fern is native to North America. It prefers rich, moist, well-drained wooded slopes, ravine bottoms, and rock faces with a lot of moisture. Note: The photos from Ice Glen in Stockbridge MA look more like southern maidenhair fern than northern. But southern maidenhair fern is well outside of its natural range here, and a list of Ice Glen species includes the northern variety, so I have tentatively assumed that these photos are the northern. Personally I think they are central maidenhair fern. Okay ... kidding ... but it is very likely that this fern is one of the other 250, barely documented species of Adiantum. Plants: Plants are deciduous, 12-30" (30-75 cm) tall. Stems are reddish-brown to black and wiry; roots are also wiry, and black. Leaves: Fronds are 8-20" (20-50 cm) long. Fruits: Spores are found on the outer edges of spore-bearing pinnae, and may cause the edges to fold. Online References:
