Campyloneurum ensifolium J.Sm.
Descripción
Rhizomes short-creeping, usually not pruinose, 2–4(–5) mm diam.; rhizome scales dense, tan to brownish, ovate-lanceolate, 3–4 X 1–1.5 mm, clathrate, the cells roundish to squarish or at least isodiametric; fronds 15–60 cm long, clumped (1–4 mm apart); stipes absent or extremely short, not clearly demarcated; blades coriaceous or thick-chartaceous, linear, 0.4–1 cm wide, gradually tapering at bases to the rhizomes or nearly so, longacuminate at apices, often curved, margins often strongly revolute and cartilaginous; lime dots absent adaxially; areoles 1 or 2 rows between midribs and margins, excurrent veinlet one per primary areole; main lateral veins immersed and not discernible, secondary veins irregularly anastomosing; sori mostly in single rows running the length of the blades, one row on each side of the midrib, rarely an incomplete, irregular second row present outside of the first row.A

Discusión taxonómica
This species is closely related to C. angustifolium and is often regarded as a variety of that, but Lellinger (1988) and León (1992) clarified the species’ differences, namely that C. ensifolium has rhizome scales with cells rounded to squarish or at least isodiametric (vs. elongate, 2–3 times as long as wide), scales generally acute at the tips and curling at the edges, and blades often narrower and usually curved (vs. straight). From C. amphostenon, C. ensifolium differs by the narrower, curved, coriaceous and revolute-margined blades, fewer rows of vein areoles and sori between midribs and blade margins, narrower rhizome scales, and occurrence at lower elevations.
Campyloneurum ensifolium seems to occur predominantly along the Pacific Coastal states in Mexico to El Salvador (and perhaps further south). It is certainly much more common in Mexico than C. angustifolium in states northwest of Guerrero.
