Description:
Species Description - Rhizomes compact, stout, 5–8 mm diam.; rhizome scales linear-lanceolate, mostly 15–20 x 2 mm, orange-tan, tinged with lustrous black, with attenuate apices and irregular hair-like lateral projections; fronds 30–60 x 3.7–6.5 cm, 0.5–1.5 cm distant; phyllopodia distinct, ca. 1 cm long; stipes 1/3–2/5 the frond length; blades narrowly elliptic, bases cuneate at 25–50º angle, apices acute to acuminate, coriaceous; veins obscure, free, simple to 2-forked; hydathodes absent; adaxial surfaces glabrous or with sparse dark trichomidia; abaxial surfaces with scattered dark brown stellate trichomidia, mostly 0.2–0.4 mm; fertile fronds slightly shorter to slightly longer than the sterile, stipes ca. 1/2 the frond length, the blades 2/5–3/4 the width of the sterile, intersporangial scales absent.

Ab E. sartorii squamis rhizomatum grandioribus nigrescentibus differt. (Dedicated to the senior author’s research assistant, Leone (Lee) Brown, who did so much to bring this manuscript to completion.)
Elaphoglossum leebrowniae is distinct in the E. sartorii complex by its rhizome scales large, spreading, tinged with black, and fertile fronds about half as broad as the sterile.
