Elaphoglossum setigerum (Sodiro) Diels, Nat. Pflanzenfam. 1(4): 333. 1899. ( Fig. 35A–E )

Range: — Mexico to Bolivia; Hispaniola.

Ecology: —Fairly common; epiphytic in humid forests; 2000–3000 m.

Notes: —In many specimens, the blade margins have shallow emarginations (use magnification) usually between the vein apices. In some specimens, the emarginations are so deep that the blades are crenulate. The scales on the abaxial blade surfaces are often reduced to ca. 0.3 mm wide and appear rounded—an unusual characteristic among the subulate-scaled species.

Elaphoglossum smithii (Baker) Christ, Neue Denkschr. Allg. Schweiz. Ges. Gesammten Naturwiss. 36(1): 106. 1899. ( Fig. 18M–P )

Range: —Hispaniola, Lesser Antilles, Costa Rica, Panama, Bolivia (CO, LP).

Ecology: —Uncommon; epiphytic in humid forests; 1000–2600 m.

Notes: —This is one of the few subulate-scaled species of Elaphoglossum that sometimes, but not always, has glabrous blade surfaces. When fresh, the blades are thick and shiny. Other distinctive characteristics are the stramineous petioles and lanceolate blades (vs. linear-lanceolate in related species). It is uncertain if the Bolivian specimens belong to the same species as those from the Caribbean region.
