Anemia oblongifolia (Cav.) Sw.
Descripción
Rhizomes horizontal, compact, short-creeping, 5–10 mm diam.; rhizome hairs orange; sterile fronds spreading to prostrate, somewhat rosette-like, 2.5–15 cm long; stipes generally less than 1 cm long, 0.3–1.5 mm diam., stramineous, hirsute; blades narrowly oblong to narrowly oblanceolate, 1-pinnate, 2–3.8 cm wide, papyraceous to coriaceous; pinnae (3–)6–10 pairs, opposite to subopposite, oblong, dimidiate, cuneate at bases, apices obtuse, margins entire to minutely denticulate, terminal pinnae usually obdeltate; blade surfaces hirsute to tomentose; veins free; fertile fronds spreading to erect, stipes nearly lacking to 1⁄2 the frond length; fertile pinnae approximate to the sterile pinnae, far surpassing the sterile blades in height; spores striate, ridges smooth, broad, closely spaced; 2n=ca. 380 (Oax).A

Discusión taxonómica
There is variation in number of pinnae, stipe length, hairiness, texture, marginal teeth, and plant size. There are several species of this complex, however, in the Planalto of Brazil. The exact chromosome number has not been determined, but the number seems high (perhaps 2n=380 (decaploid)).
A few plants from eastern Oaxaca and Chiapas (Mickel 1204, 1207, 5962, 5985, NY; Breedlove 36813, DS) have longer stipes, more rounded pinnae, more denticulate margins, and thinner texture, but do not appear distinct enough to be treated as a separate taxon.
