Description:
Species Description - Plants terrestrial or occasionally epiphytic. Rhizome short, suberect, concealed by the stout stipe bases, the apex clothed with a dense tuft of narrowly lanceolate-attenuate, glabrous, light orange-brown scales, ca. 8 x 0.8 mm , terminating in a long hairlike apex. Fronds closely clustered, suberect or spreading, 1-2.2 m long; stipes mostly 6-20 cm long, deciduously fibrillose-scaly, the scales spreading, linear-filiform, concolorous, pale orangebrown, basally attached. Blades linear, 50-100(-200) x 6-14 cm, slightly narrowed toward the base, the apex apparently of indeterminate growth; rachis light brown, deciduously fibrillosescaly, the scales glabrous; pinnae numerous, narrowly oblong or narrowly triangular-oblong and nearly scythe-shaped, 3-7 x 0.8- 1.3 cm, acutish to subacuminate at apex, subcordate and obtusely auriculate at base, the auricle often overlapping the rachis, the margins bluntly serrulate to lightly crenate; tissue deciduously fibrillose to glabrate; veins 1- or 2-forked. Sori supramedial, rather close; indusium round-cordate to nearly kidney-shaped, the sinus usually open and U-shaped.
Distribution and Ecology - Uncommon on shaded banks, borders of thickets or in secondary forests. Upper slopes and summit of Bordeaux Mountain (P40433). Also on St. Croix, St. Thomas, and Tortola; cosmopolitan but perhaps naturally distributed in Florida, the Bahamas, Greater Antilles, and Mexico.
