Eriosorus elongatus (Grev. & Hook.) Copel., Gen. Fil. View in CoL 58. [Ann. Crypt. Phytopath. 5]. 1947.

= Jamesonia elongata J.Sm., Hist. Fil. 168. 1875.

Range: — Ecuador to Bolivia (CO, LP, SC).

Ecology: —Common; terrestrial in humid regions among rocks or shrubs, often along roadsides, forest edges, or in rocky pastures; 2400–3700 m.

Notes: —Blades narrow, linear, 1-pinnate to 1-pinnate-pinnatifid; pinnae nearly as long as broad; ultimate segments bifid, each lobe with (1)3 or 4 veins; blade apices curled. This taxon was considered a hybrid between E. cheilanthoides and a Jamesonia sp. (possibly J. alstonii or J. goudotii ) by A. Tryon (1970), but it is common, widespread, produces normal-looking spores, and apparently reproduces sexually. However, true hybrids with malformed spores apparently do occur in Eriosorus / Jamesonia and look confusingly similar.
