Kessler, Michael, Moran, Robbin C., Mickel, John T., Matos, Fernando B. & Smith, Alan R., 2018, Prodromus of a fern flora for Bolivia. XXXV. Dryopteridaceae, Phytotaxa 353 (1), pp. 448-450 : 448-450

Elaphoglossum ellenbergianum M.Kessler & Mickel, Brittonia 58(2): 104. 2006. ( Fig. 8A–J )

Range: —Endemic to Bolivia (CO, LP).

Ecology: —Rare; epiphytic in semihumid forests; 2900–3050 m.

Notes: —Differs from E. tectum in having erect, funnel-shaped, orange abaxial blade scales with a distinct scale body. These scales are similar to those of E. neei , but that species has lanceolate, long-ciliate (vs. peltate, short-ciliate) petiole and abaxial blade scales.

= Elaphoglossum cristatum Ballenth., Dudenh. & M.Kessler, Brittonia 61(1): 46. 2009.

Range: —Hispaniola; central Mexico; Guatemala; Costa Rica and Panama; Andes from Venezuela to Bolivia (CO, LP).

Ecology: —Very common; epiphytic, saxicolous, and terrestrial in humid forests, on rock faces, along roadsides, in grasslands, and among rocks; (1800–) 2450–4600 m.
