Description:
Species Description - Rhizomes short-creeping, to 9 mm diam.; rhizome scales linear-lanceolate, reddish orange, to 12 mm long, with short teeth; fronds clumped, 10–57 x 1.2–4 cm; phyllopodia absent; stipes 1/4–1/2 the frond length, with scales reddish orange, spreading, subulate, slightly toothed, to 4 mm long; blades linearlanceolate, 10–15 times as long as wide, chartaceous, bases rounded, truncate, or broadly cuneate, apices acuminate; veins distinct, free, simple or once-forked, 1.5–2.5 mm apart, at 60– 70º angle to costa; hydathodes evident; blade scales abundant, reddish orange, subulate, slightly toothed, denser at margins, spreading to 5–6 mm long, usually less scaly on the adaxial surfaces; fertile fronds slightly shorter that the sterile, to 38 cm long, 2.5 cm wide, with longer stipes ca. 3/4 the frond length, bases subcordate, apices acute, intersporangial scales absent.

Acrostichum setigerum Sodiro, Anales Univ. Centr. Ecuador 4: 174. 1890. Type. Ecuador. Cordillera Occidental, cerca de Nono, Sodiro s.n. (QPLS). Elaphoglossum crinipes C. Chr., Kongl. Svenska Vetenskapsakad. Handl. III, se´r. 3, 16(2): 76, t. 17, f. 1-2. 1936. Type. Haiti. Croix-des-Bouquets, Badeau, Ekman 7708 (BM!; isotype US!).
This species closely resembles E. villosum (Sw.) J. Sm. of the West Indies, but is distinct by E. villosum having scales among the sporangia and blades with narrowly cuneate bases and caudate apices.
