dryoptère de Clinton

Clinton's Wood Fern, Dryopteris clintoniana, is a large, robust fern in the family Dryopteridaceae native to eastern North America, ranging from Nova Scotia and New England south through the Appalachian Mountains and the Great Lakes region. It inhabits rich, moist, shaded forests including floodplain woodland, mesic slopes, and forested wetland margins, growing in soils with abundant leaf litter and high organic matter content. Clinton's Wood Fern is a tetraploid hybrid fern, arising from crosses between Dryopteris cristata (Crested Wood Fern) and Dryopteris goldiana (Goldie's Fern), and inherits intermediate characteristics from both parents. The fronds are large, once-pinnate to pinnate-pinnatifid, with broad, dark green pinnae that have rounded, finely toothed lobes. Like many hybrid ferns, it is fertile and reproduces apogamously. The species is named for DeWitt Clinton, as is Clinton's Bulrush, reflecting his early contributions to American natural history. Clinton's Wood Fern is considered relatively rare within its range, partly because it requires the specific combination of parental species in suitable habitat. Threats include forest clearance, invasive species, and changes in forest hydrology. It is listed as a species of conservation concern in several northeastern states.
