Description:
Species Description - Rhizome moderately to long-creeping, to 2 mm diam.; rhizome scales maroon, lustrous, linear, to 6 mm long, short-toothed, especially along the elongate tip; phyllopodia indistinct or lacking; fronds distant, 7.5-22 cm long, 1.4-2.2 cm wide; stipe 1/5-½ the frond length, with scales linear, maroon, ca. 2 mm long, toothed, appressed; blade narrowly elliptic, papyraceous, apex acute to acuminate, base cuneate; veins evident, free, simple or rarely once-forked, 1.5-2.5 mm apart, at 5060° angle; hydathodes evident; blade scales brown, linear-lanceolate with flared base, evenly and sparsely distributed on blade, not noticeably along margin, 2 mm long, with short teeth; fertile fronds smaller than the sterile; fertile blade ca. 3.5 cm long, 1.2 cm wide; stipe ca. 4/5 the fertile frond length; scales lacking on lower surface; spores with short crests and holes in spore surface.

Discussion:
Type. Mexico. Chiapas: Mun. Rayón, 10 km above Rayón Mezcalapa along rd. to Jitotol, Breedlove 32649 (DS!). Among the subulate-scaled Elaphoglossums in Oaxaca, E. chiapense is distinct by its long-creeping rhizome.
