Elaphoglossum ballivianii Rosenst., Repert. Spec. Nov. Regni Veg. 12: 474. 1913. ( Fig. 25A–C )

Range: —Presently known only from Bolivia (CO, LP), but probably more widespread.

Ecology: —Common; epiphytic in humid forests; 800–2200(–3200) m.

Notes: —Very nondescript, lacking clear identification characters. Previously often identified as E. petiolatum (Sw.) Urban from Mexico to Peru and Brazil, but that species has resinous dots and/or scales on the abaxial blade surfaces.
