Etymology From poly. many, + blepharum, fringed like an eyelash
Description Rhizome: erect, short, massive, scaly.
Frond: 100 cm high by 25 cm wide, evergreen, monomorphic , blade/stipe ratio: 4:1.
Stipe: grooved, tan, darker at base, green only near the tip of the frond; old stipes persistent, densely scaly throughout; larger scales at base of stipes narrowly lanceolate to broadly so, light brown to reddish brown, about 2 cm long, vascular bundles: 4 or more, in an arc.
Blade: 2-pinnate, ovate, acute at apex, glossy, papery, scales on rachis narrower upwards, nearly hair-like on uppermost part, fibrous-like scales on lower surface.
Pinnae: 15 to 25 pair, 15-25 mm wide, lower pinnae bending forward, the lowest most, in some specimens 90�, overlapping, also bending downwards; pinnules eared, upper one prominent, spine-tipped; costae grooved above, discontinuous with the rachis; veins free, forked.
Sori: round, medial, between midrib and margin, indusium: peltate, papery, white, shriveling, central, sporangia: tan, then brown.
Dimensionality: lower pinnae bending forward, the lowest most, in some specimens 90�, overlapping, also bending downwards.
Culture Habitat: floor of light forests, slopes, grasslands. Distribution: Japan, southern Korea, eastern China. Hardy to -25�C, USDA Zone 5.
Distinctive Characteristics in unfurling the tip of the frond droops, tassel-like, giving rise to the common name: see the photo labeled 'specimen' above
