Lindsaea stricta (Sw.) Dryand., Trans. Linn. Soc. London 3: 42. 1797.

Range:— Greater Antilles; southern Mexico to Bolivia (LP, SC) and Brazil.

Ecology:— Locally common; terrestrial among rocks, on sandstone, in wet sand, and on exposed ridges, in humid forest regions, accidentally as an epiphyte ( Obermuller et al. 2014); to 2400 m.

Notes:— The Bolivian specimens can be assigned to var. stricta ; two other varieties occur in northern South America. Differs from Lindsaea portoricensis by broader indusia (0.3–0.5 mm vs. ca. 0.3 mm wide). Petioles stramineous to pale reddish brown, abaxially rounded; blades 1- to 2- (rarely 3-) pinnate; rachises abaxially rounded to angular (but without pale wings); pinnules coriaceous with hidden veins, roundish to 1.5 times longer than wide; distal segments gradually reduced; indusia strongly erose, 0.3–0.5 mm wide.
