Description:
Species Description - Rhizome short-creeping, 1-2 mm diam.; rhizome scales linear, with sparse and irregular short teeth, brown to dull orange, 3-5 mm long; phyllopodia lacking; fronds clumped, 11-18 cm long, 1.0-1.5 cm wide; stipe slender, 1/5-2/5the frond length, moderately clothed with slender, dull orange subulate spreading scales, 2-3 mm long; blade narrowly elliptic, membranaceous, apex gradually acuminate, base cuneate; veins conspicuous, free, mostly simple or rarely once-forked, 1.5-2 mm apart, at ca. 40° angle; hydathodes conspicuous; blade scales subulate, dull orange, moderately and uniformly clothing the blade surface, more so on the lower surface, longer and spreading at the fertile fronds nearly as long as the sterile but more elliptic with acute apex, ca. 3 cm long and 1.1 cm wide, and longer stiped (ca. ¾ the length), abundant scales mixed with the sporangia; spores with many narrow highly perforated crests.

Discussion:
Acrostichum setosum Liebmann, Mexic. bregn. 169 (seors. 17). 1849, non Wallich, 1828, nom. nud. Acrostichum recognitum Fournier, Mexic. pi. 1: 67. 1872, nom, illeg. superfl. Type. Mexico. Veracruz: Barranca de Huitamalco, Liebmann [PI. Mex. 2433] (C!). Elaphoglossum catherinae Underwood ex Maxon, Contr. U.S. Natl. Herb. 13: 5. 1909. Type. Guatemala. Alta Verapaz: Pansamalá, Türckheim [Donnell-Smith 1003] (US!; isotypes K!, NY!). This species is superficially much like E. crinipes, but E. setosum can be distinguished by the smaller size, the presence of scales among the sporangia, and quite different spores. It also resembles E. lindenii, which has more broadly elliptic blades and darker blade scales.
