( Fig. 47A–D ) Range: —Antilles; Guianas, Venezuela and Colombia to Bolivia (CO, LP). Ecology: —Fairly common; epiphytic in humid forests, to 1500(–1750) m. Notes: —The laminae typically dry blackish. Most similar to E. nigrescens , but that species has abundant glandular dots on the abaxial blade surfaces, and minute scales with acicular teeth near the laminar margins. Elaphoglossum flaccidum is more thin-textured than E. glabellum and has more widely spaced veins. Its vein tips are expanded laterally and often united.
