Dryopteridaceae
Species Description - Rhizomes short-creeping, ca. 5 mm diam.; rhizome scales castaneous, lustrous, linear-lanceolate, toothed, 4–6 mm long; fronds clumped, 25–60 x 1.4–3.1 cm; phyllopodia distinct, short; stipes 1/8–2/5 the frond length, with scales linear, tan, ca. 2 mm long, ciliolate, spreading, others smaller, stellate; blades narrowly elliptic, chartaceous, bases narrowly cuneate, apices caudate; veins evident to obscure, free, simple to once-forked, ca. 1 mm apart, at ca. 70º angle to costa; hydathodes absent; blade scales orange, linear, highly skeletonized, very long-ciliolate, the hairs 3–4 times as long as the scale body width, plane or the hairs turned upward, loosely covering the abaxial surfaces, adaxial surfaces glabrous with age, with narrowly lanceolate scales with long hair-teeth or substellate with long teeth; fertile fronds slightly shorter or longer than the sterile fronds, stipes 1/3–1/2 the frond length, with a few reduced scales on abaxial costae, but not among the sporangia.

Elaphoglossum vestitum is most closely allied to E. rubescens, resembling it in rhizome scale color and texture, ciliate blade scales lightly covering the laminae, and lax fronds with caudate tips. The latter can be distinguished by the rhizome scales not (or only weakly) toothed, the stipes often with resin dots, and the blade scales with the teeth and margins upturned. These two species may be only varietally distinct, and several specimens from Chiapas overlap in morphology. Elaphoglossum auricomum belongs to the same complex, but has more abundant, spreading stipe scales, the rhizome scales are lighter in color, and the blades have acuminate apices. Some specimens of E. paleaceum have blades only lightly covered with scales, but they have black scales on the stipes and abaxial rachises.
