Lindsaea lucida Blume

Rhizome short-or very short-creeping, c. 1 mm ø; scales rather dark brown, to 1 mm long, acicular, to 6-seriate at the base, the greater part uni-or biseriate. Leaves very close; petioles stramineous to reddish brown, quadrangular, adaxially hardly sulcate. Lamina linear, c. 10-40 cm long, c. 10-25 times as long as wide, simply pinnate; rachis like the petiole. Pinnules spreading or slightly ascending or decurved, the upper ones subcontiguous to slightly overlapping, the lower ones gradually more widely spaced; larger pinnules 1.5-2.5 times as long as wide, firmly herbaceous, medium to dark green or olivaceous when dry. Upper pinnules reduced; larger pinnules mostly incised. Veins immersed, evident, once or twice forked or the outer ones simple, free; a costa scarcely developed. Indusium pale, entire; spores trilete.
