Descripción
Rhizomes short-creeping, to 3 mm diam.; rhizome scales linearlanceolate, lustrous, concolorous, brown, somewhat resinous, to 4(–20) mm long, entire; fronds clumped, 24–74 X 1.7–4.5 cm; phyllopodia indistinct; stipes 1⁄5–1⁄3 the frond length, sparsely clothed with minute, stellate, appressed hairs; blades narrowly elliptic, very thin, bases cuneate, apices long acuminate; veins evident, free, simple or once-forked, 1.5–2 mm apart, at 60–70° angle to costa; hydathodes absent, but vein tips expanded laterally, sometimes uniting; blade scales absent except for a few minute, stellate, reddish, resinous hairs, mostly on the abaxial blade surfaces; fertile fronds about equal to the sterile in length, but with longer stipes (ca. 1⁄2 the fertile frond length) and narrower blades, scales absent from abaxial blade surfaces.A

Discusión taxonómica
This is distinguished from other species by its very thintextured blades and laterally expanded vein ends. Specimens from Chiapas seem to have shorter, more resinous rhizome scales than do those of Guatemala, but since both conditions are found in Oaxaca, it is presumed to be a variable character in the species. Breedlove 32218, NY, has rhizome scales to 20 mm long. From E. decursivum, E. lonchophyllum differs in having longer stipes and blades not long-decurrent.A
