Woodsia neomexicana Windham
Descripción
Rhizomes horizontal to ascending, compact, 2–3 mm diam.; rhizome scales bicolorous orange-tan with black central stripe, linear-lanceolate, entire; fronds 4–30 cm, clumped; stipes 1⁄5–1⁄3 the frond length, stramineous to light brown, with scales at bases, sparsely glandular throughout; blades pinnate-pinnatifid to bipinnate, 1.5–4.5 cm wide, narrowly oblong, widest at or just above middle of blades; pinnae 6–11 pairs, oblong, mostly obtuse, margins with sparse short-glandular hairs; abaxial blade surfaces nearly glabrous; indusia segments plate-like at bases with filamentous tips equalling or somewhat exceeding the sporangia, with widely scattered glands and 1–2-celled translucent projections on most teeth; spores 48–57 µm; 2n=152 (Ariz).A

Discusión taxonómica
Woodsia neomexicana is thought to be derived from hybridization between W. oregana and W. phillipsii and has intermediate blade dissection (Windham, 1993). Plants are only slightly glandular, the blade margins are somewhat crustose, always with some projections on teeth, and the indusia are filamentous—less obviously than in W. phillipsii—with filaments not far exceeding the sporangia. Woodsia neomexicana apparently backcrosses to W. phillipsii.
Woodsia neomexicana has a range similar to W. mexicana but is distinct in its completely filamentous indusial segments and fewer glands.
