Woodsia cystopteroides Windham & Mickel
Descripción
Inter species Woodsiae laminis glabris marginibus nitidis cum dentibus conicis translucentibus distincta. (Alluding to its close resemblance to plants of Cystopteris.)
Rhizomes horizontal to ascending, compact, 3–4 mm diam.; rhizome scales linear-lanceolate, bicolorous orange-tan with black central streak, entire; fronds 12–22(–30) cm, clumped; stipes 1⁄4–1⁄3 the frond length, stramineous, with scattered linear-lanceolate scales at bases; blades bipinnate to bipinnate-pinnatifid, 3–5.5(–8) cm wide, lanceolate, proximal pinnae reduced; rachises glabrous except for occasional scales 1 mm long; pinnae 6–14(–17) pairs, narrowly deltate, pinnules obtuse; margins coarsely toothed, the teeth firm, lustrous, and slightly inrolled; adaxial blade surfaces with lustrous teeth having elongate cells directed toward teeth tips; abaxial blade surfaces glabrous; indusial segments plate-like half their length, divided into filaments distally; spores 37–48 µm.

Discusión taxonómica
Fronds of Woodsia cystopteroides have stipe bases stramineous (though may be dark at attachment), are 2-pinnate, nearly glabrous, with lustrous margins having elongate cells directed toward teeth tips, smooth, lustrous segment margins terminating in sharp conical translucent teeth, and indusial segments united proximally over half their length, divided into filaments distally.A
