Anemia humilis (Cav.) Sw., Syn. Fil. 156. 1806.

Range:— Mexico to Bolivia ( CH?, LP, SC), and the Guianas to Brazil and Argentina.

Ecology:— Uncommon; terrestrial in semihumid to dry forests, often on rocky slopes; 500 – 2000 m.

Notes:— Similar to Anemia oblongifolia (Cav.) Sw. , under which it has historically been subsumed. Anemia oblongifolia is now accorded a range from Honduras to Panama, Colombia to Guyana, and Brazil, and is not known from Bolivia ( Mickel 2016). The outer sterile leaves of A. humilis often have very short petioles and form a rosette. Anemia presliana Prantl was treated by Mickel (2016) as occurring in Bolivia, and distinct from A. humilis , and A. presliana has approximately the same range. Specimens determined as A. presliana from Bolivia by Mickel (e.g., Buchtien 7023, UC; Mickel cited Buchtien 2023, UC, probably a typographical error, and from the same locality) seem indistinguishable to us from those determined as A. humilis by Mickel. For now, we exclude A. presliana , the more recent name, from the fern flora of Bolivia.
