Amauropelta nevadensis

Nevada marsh fern, Nevada Marsh Fern

Family: Thelypteridaceae · Type: Fern · Native

Nevada marsh fern is a native fern found in the Klamath Ranges, northern Coast Ranges, and northern Sierra Nevada Mountains in springy hillsides and seepage areas at elevations of 365 to 1,700 meters. Growing with densely clustered leaves 40 to 100 centimeters long and 8 to 15 centimeters wide, this fern has a creeping rhizome that typically becomes dormant during winter. Its blade is thin and distinctive, featuring many short-stalked resinous glands on the underside between and along the veins, giving the leaf a unique textured appearance. The fern's pinnae are deeply lobed with approximately oblong-shaped segments that are entire to shallowly crenate, creating an intricate leaf structure. Its stipe is covered with persistent tan lance-ovate scales, adding to the fern's delicate and complex botanical character.
