Description
Species Description - Rhizome horizontal, compact, short-creeping, 5-6 mm diam.; rhizome hairs orange; fronds erect, 7-14 cm tall; stipe 1/3-½ the frond length, stramineous, subglabrous to very lightly hairy; blade narrowly oblong, 2.5-3.2 cm wide, once-pinnate, chartaceous; pinnae 3-5(-7) pairs, mostly opposite, cuneate-obovate to rhomboid or subflabellate, often excavate on lower margin, 6-10 mm wide, 1.1-1.8 cm long, erose-serrulate, glabrous; fertile fronds similar in size and form to sterile or slightly longer-stiped; fertile pinnae approximate to the sterile pinnae, shorter than or equal to the sterile blade in height; spores tetrahedral-globose, with smooth, narrow, spaced ridges.

Discussion
Type. Mexico. Oaxaca: Dist. Juchitán, 14 km E of Tapanatepec on Rte 190, 6 km W of Chiapas border, 1200' [360 m], 4 Aug 1971, Mickel 5984 (NY!). This species is closely allied to A. hirsuta but has short fertile pinnae and unincised, glabrous sterile pinnae. The nakedness and serrulate margin are suggestive of A. affinis of western Mexico, but the shorter fertile pinnae and small size are distinctive. Anemia familiaris also resembles A. obovata (Underwood) Maxon of Cuba, which has glabrous, unincised pinnae. However, it has only 2-4 pairs of pinnae, which are broader, more obovate to oblong, and the pinna bases are not as narrowly cunneate.
