Descripción
Rhizomes short-creeping to ascending, ca. 3 mm diam.; rhizome scales linear, maroon, to 8 mm long, with short teeth; fronds clumped, 7–40 X 1.5–4 cm; phyllopodia absent; stipes 1⁄2–2⁄3 the length of the sterile fronds; stipe scales orange to maroon, subulate, wide-spreading, 2–3 mm long; stipes also with a few minute erect glandular hairs; blades oblong-elliptic, 3–6 times as long as wide, rounded to broadly cuneate at bases, acute to acuminate or sometimes cuspidate at apices; veins evident, ca. 2 mm apart, at 60–70° angle to costa; hydathodes distinct; blade scales subulate, orange to maroon, sparse on the abaxial surfaces, rare adaxially, spreading from the margins, 2–3 mm long; fertile fronds shorter than the sterile, the stipes 3⁄4–4⁄5 the length of the fertile fronds, the blades ovate, rounded to truncate at bases, 1.7–5 X 0.8–1.5 cm, the apices obtuse, the blades often folded at the midveins, scales present on the midveins abaxially, but lacking among sporangia.A

Discusión taxonómica
This species is closest to E. setigerum, which is distinguished by its sterile blade length/width ratio of 10–15:1 (vs. 3–6:1), and more southern distribution (Gro, Oax, Chis). Elaphoglossum monicae closely resembles E. lindenii in the sometimes cuspidate blade apices, subulate scales, glands on the stipes, and red-brown rhizome scales, but in E. monicae the blades are more oblongelliptic and the spores are echinate-reticulate, 37–49 (avg. 43) µm long, rather than with fenestrate crests and 23–33 (avg. 29) µm long.A
