Discusión taxonómica

Elaphoglossum baquianorum resembles E. tambillense (Hook.) T. Moore in form of the blades, with the scales only on the costa and margin, but differs in its thicker rhizome (0.5-0.8 mm diam. vs. 0.3-0.5 cm), longer rhizome scales (5-10 x 0.5-0.8 mm vs. 4-7 x 0.2-0.5 mm), longer fronds [the sterile (15-)20-45 cm vs. 15-25 cm, and the fertile 17-28 cm vs. 5-10 cm], bigger fertile blade (4.5-10.5 x 1.3-2.8 cm vs. 2.5-3.5 x 1.2-1.5 cm), hydathodes absent (vs. present), and scaly blade margin (vs. no scaly). The shape of the blades of E. baquianorum is similar to that of E. pallidum (Baker ex Jenman) C. Chr., but the rhizome scales are plane and yellowish (vs. twisted and blackish), with shorter blade (3.0-3.8 vs. 4.3-6.4 times longer than wide), and scaly blade margin (vs. no scaly). Also is similar to E. erinaceum in blade shape, but differs in narrow (0.5-0.8 mm 1.0-2.5 mm) and brown to blackish (vs. yellow to orange) rhizome scales, more dense stipe scales, larger [9-22 x 3.0-5.8 cm vs.(14-)20-40(-65) x (4-)5-9(-11.5) cm] blade, smaller [0.7-1.2 x 0.1-0.3 mm vs. 2-6 x 0.2-0.6(-1) mm] and present only in margin (vs. costa and margin) blade scales.
This species is dedicated to park rangers Bernardo Picado and Errol Morales, to trail-blazers ("baqueanos") Freddy Acuña, Eduardo Alfaro, Rodrigo Mora and Juan Solano, and to engineer Ricardo Segura from La Amistad International Park.
