    Species Description - Rhizomes horizontal, compact, short-creeping, 4–8 mm diam.; rhizome hairs orange; sterile fronds erect, 8–20 cm long; stipes 1/4–1/3 the frond length, 0.4–1.9 mm diam., stramineous, hirsute; blades oblong to deltate, 1-pinnate, 2.5–9 cm wide, chartaceous to subcoriaceous; pinnae 5–9 pairs, opposite to subopposite, narrowly oblong, dimidiate, truncate at base, tapering toward apices, acute at tips, margins entire to minutely denticulate or erose, occasionally shallowly incised and forming 1–3 lobes on the acroscopic side of the lower pinnae; blade surfaces lightly hirsute to glabrous; veins free; fertile fronds to 25 cm tall, stipes 3/5–4/5 the frond length; fertile pinnae approximate to the sterile pinnae, far surpassing the sterile blades in height; spores striate, ridges spiny; 2n=228 (Jal, Nay, Oax, Trin).

    Anemia helveola Fe´e, Me´m. Foug. 9: 41. 1857. Type. Mexico. Oaxaca: Galeotti 6586bis (G?, not seen). The only specimen we have seen labelled as A. helveola is Galeotti 6541 (BR), which is A. pastinacaria. If indeed the type of A. helveola is that species, then A. helveola has priority. In that case, conservation of A. pastinacaria would be appropriate.

    This species is distinct with its narrowly deltate fronds, pinnatifid apices, and oblong, acute pinnae. The spores are often a mixture of well formed (having narrow ridges and being short to long-tuberculate) and malformed, suggesting this species is a triploid apomict, at least in Mexico.
