Elaphoglossum hernandeziae A.Rojas
Descripción
Elaphoglossum hernandeziae differs from E. dissitifrons Mickel by its shorter rhizome, with longer and relatively narrower, lanceolate to linear-lanceolate scales and blackish costal scales.
Rhizome 2-3 mm in diameter, creeping, distance between fronds 2-5(−10) mm; rhizome scales 5-10 × 1-2 mm, lanceolate, gold or with brown patches, peltate, flaccid, patent, marginally entire to short-ciliate; fronds 18-46 cm long; phyllopodia 7-15 mm long; stipe 5-23.5 cm long, 1/2-1/4 of the frond length, stramineous, scaly at least at the base, the scales 2-5 × ca. 1 mm, the basal ones marginally entire and the others longciliate; blade 13-24 × (2.1–)2.5-4.3 cm, elliptic, oblong-elliptic or oblanceolate, coriaceous, basally cuneate, apically obtuse to rounded; costa stramineous, scaly or glabrous, the scales 1-2 × ca. 0.5 mm, lanceolate, gold-brown to brown, sparse, marginally with lateral processes; laminar tissue glabrous on both surfaces; veins few evident; fertile fronds 13-37 cm long; stipe (3−)10-20.5 cm long; blade 9.5-17 × 1.6-2.7 cm, elliptic to oblong, basally cuneate, apically acute to obtuse; intersporangial scales absent.
This species is dedicated to Ruth Karina Hernández Cibrián, pteridologist in Honduras, who collaborated with the Celaque expedition in 2012.A

Discusión taxonómica
Elaphoglossum hernandeziae differs from E. dissitifrons by its shorter [fronds distant (0.2−)0.5-1 cm, vs. 0.8-1.7 cm] rhizome, longer [(4−)7-12 mm, vs. 5-7 mm] and relatively narrower [1-2(–3) mm, vs. 1.5-3.0 mm)] rhizome scales, which are lanceolate to linear-lanceolate (vs. ovate to ovate-lanceolate), and blackish (vs. yellowish-brown) costal scales.
This taxon was previously published as Elaphoglossum karinae A. Rojas, but the type specimens of two other species (E. clewellianum Mickel and E. martinezianum A. Rojas) were mistakenly cited among the paratypes. Thus the name E. karinae is illegitimate, according to Article 52.1 of the International Code of Nomenclature, for which reason the taxon is here provided with another name.A
