Descripción
Rhizomes suberect to erect, usually unbranched; rhizome scales concolorous, brown, ovate to ovate-lanceolate, 3.5–10 X 1–3(–4) mm, margins denticulate to ciliate; fronds mostly 60–125 cm long; stipes 1⁄3–1⁄2 the frond length, with dense brownish, ovate to lanceolate scales at bases; blades ovate to ovatelanceolate, 35–65 cm long; rachises glabrescent or with sparse, thin, curled, fibrillose scales 2–4 mm long, mostly at pinna bases; buds absent from axils of distal pinnae; pinnae 8–18 lateral pairs, linear-lanceolate, straight to often falcate, mostly 9–18 X 1.5–3.5 cm, bases rounded to broadly cuneate, apices attenuate, lowermost pinnae inequilateral, not auriculate, distal pinnae equilateral, margins spinulose most of their length, decidedly so at pinna apices; veins anastomosing about 2⁄3 the way to pinna margins; sori in 2–4(–5) series between costae and pinna margins, inner row mostly (2–)3–5 mm from costa, outer row 1–3 mm from margin; indusia tan, caducous, 0.8 mm diam., flat or concave, not umbonate; 2n=82 (Chis, Hgo, Ver).A

Discusión taxonómica
From P. nobilis, P. remotispora differs in having anastomosing veins, first series of sori usually more distant from the costae, broader pinnae, and occurrence at generally lower elevations. It appears to be absent from western Mexico, where P. nobilis is relatively common. This appears to be a classic case of ecogeographic speciation, with P. remotispora very common on the Caribbean slope and in southern Mexico, and P. nobilis very common on the Pacific slope; however, there is slight interdigitation of the ranges. See discussion under P. nobilis for additional comments.A
