Description:
Species Description - Rhizome wide-creeping, 1.5-2 mm thick, at apex and nodes bearing lustrous reddish-brown, lance-attenuate scales 3-4 mm long, these with contorted tips and subdenticulate, sparsely ciliate margins. Fronds few, distant, erect; sterile fronds 7-19 cm long; stipes usually equalling or longer than the blades, 3.5-11 cm long, strawcolored, narrowly grooved adaxially, naked, with dark phyllopodium up to 11 mm long or more; blades ovate, 3.5-8 cm long, 2-3.5 cm broad, obtuse at apex, cuneate at base, with cartilaginous margins; veins free, reaching the margins; tissue coriaceous, opaque, remotely and minutely scaly chiefly on abaxial side, the scales 0.15-0.3 mm in diameter, irregularly stellate with gland-tipped branches. Fertile fronds 8.5-14(-18) cm long, with stipes about three times longer than the blades; blades lanceolate to elliptic-oblong, 2.5-4.5 cm long, 1-1.5 cm broad, the apex rounded or blunt, the base short-cuneate.

Type. Sargent 3115, from summit of Monte Jayuya, Puerto Rico (US).
Closely related to Elaphoglossum scandens (Bory) Moore ofthe Lesser Antilles, which differs in its wider rhizome scales, somewhat larger fronds with more pointed blades, and in having smaller, darker, non-glandular scales on the tissue.
