Elaphoglossum madidiense M.Kessler & Mickel, Brittonia 58(2): 108. 2006. ( Fig. 5A–F )

Range: —Endemic to Bolivia (LP).

Ecology: —Rare; epiphytic in humid forests; 3450–3600 m.

Notes: —Most similar to E. unduaviense , from which it differs in its smaller size (leaves 2–11 cm vs. 12–60 cm long); rhizomes 0.7–1 mm thick (vs. 1.5–3.5 mm); phyllopodia 3–5 mm long (vs. 12–25 mm); lanceolate blades (vs. linear-lanceolate); and presence of whitish, peltate, ovate scales on the adaxial blade surfaces.
