Range: — Mexico to Panama; Hispaniola; Colombia and Venezuela to Bolivia ( CH, CO, LP, SC, TA); Argentina, Brazil, and Chile; mid-Atlantic islands, Africa, and islands of the Indian Ocean.

Notes: —A very widespread species of generally higher elevations, with affinities to species in southern South America (especially Chile); this and related species are sister to the A. raddianum clade ( Sundue et al. 2010, Hirai et al. 2016, Huiet et al. in prep.). Rhizomes long-creeping, scales with margins short-ciliate, rarely entire or sparsely denticulate; rachises glabrous; blades 3-or 4-pinnate proximally, 2-or 3-pinnate distally; pinnules entire, orbicular to flabellate, not articulate, stalked, stalks 1–3 mm long, color of stalks slightly passing into pinnule bases, bases usually symmetric, glabrous; veins ending in sinuses at pinnule margins; sori borne on distal pinnule margins, usually with yellow farina among sporangia; indusia large, occupying 1/3 of pinnule length, lunate to oblong, glabrous.
