Pellaea sagittata (Cav.) Link, Fil. Sp. 60. 1841.

Range: —Central Mexico to Colombia and Bolivia ( CH, LP).

Ecology: —Rare; terrestrial and saxicolous in semiarid regions, on dry banks, among rocks or on stone walls; 1700–3000 m.

Notes: —Rhizomes compact; rachises straight; scales on petiole bases and rachises concolorous, tan; ultimate segments ovate-deltate. Pellaea cordifolia (Sessé & Mociño) A.R.Sm. , from southwestern U.S.A. and Mexico, has historically been treated as a variety of P. sagittata (by Tryon 1957), in which case the Bolivian taxon becomes var. sagittata . Evidence suggests that both of these species may be more closely related to Astrolepis than to Pellaea (Schuettpelz et al. 2007, Eiserhardt et al. 2011).
