Elaphoglossum viride
Description
Rhizomes compact, short- to moderately creeping, 3–5 mm diam.; rhizome scales linear-lanceolate, orange-tan to dark brown, 2–3(–5) mm long, entire, margins inrolled, the cells isodiametric and distinctly concave, appearing subclathrate; fronds approximate to slightly spaced, 15–40(–65) X 15–20(–32) cm; phyllopodia distinct, ca. 1 cm long; stipes (1⁄5–)1⁄4–1⁄3(–2⁄5) the frond length, glabrous above the phyllopodia; blades narrowly elliptic, firm, narrowly cuneate at bases, long-acuminate at apices; veins scarcely visible, free, simple or once-forked, ca. 0.8 mm apart, at 60–65° angle to costa; hydathodes absent; adaxial blade surfaces glabrous; abaxial blade surfaces with scattered to sparse, minute, stellate trichomidia and occasional black scales on costal bases; fertile fronds nearly as long as, to somewhat shorter than, the sterile and about the same shape and width, stipe 1⁄2–3⁄5 the frond length, intersporangial scales absent.A

Discussion
Elaphoglossum viride closely resembles E. sartorii, but the former is distinct by the inrolled rhizome scales with isodiametric concave cells.B
