Elaphoglossum manantlanense
Description
Rhizomes short-creeping, horizontal, 2–3 mm diam.; rhizome scales linear-lanceolate, castaneous, lustrous, 3–4 mm long, inconspicuously toothed; fronds clumped, 20–33 X 1.5–2.3 cm; phyllopodia distinct; stipes 1⁄10–1⁄5 the frond length, densely scaly, the scales spreading, orange-tan, concolorous or with dark central streak, 2–3 mm long; blades narrowly elliptic, narrowly cuneate at bases, acuminate at apices; veins obscure, ca. 1 mm apart, at 80° angle to costa; hydathodes absent; blade scales scattered to overlapping, lanceolate, 1–2 mm long (to 3 mm long on the costae abaxially), orange-tan (on adaxial surfaces becoming white with age, with long hair-teeth); fertile fronds longer than the sterile, the stipes ca. 3⁄4 the frond length, the blades linear, ca. 6 mm wide, usually inrolled to appear 3–4 mm wide, the scales lanceolate abaxially along the costae, those of the adaxial surfaces much reduced.A

Discussion
Elaphoglossum manantlanense resembles E. paleaceum in the scaly blades but is distinct in the castaneous, nearly edentate rhizome scales, very short stipes (1⁄10–1⁄5 the length of the frond instead of 1⁄5–1⁄4), concolorous stipe scales (or with a dark central streak), and linear fertile blades, slightly longer than the sterile.B
