| Sumario: |
Three new species are described and another is recognized in Campyloneurum. Two species occur in Mexico to El Salvador and the others two are
present in Nicaragua, Costa Rica and Panama. The new species are Campyloneurum acutum A. Rojas, C. leoniae A. Rojas and C. madrense A. Rojas. The
first species differs from C. xalapense by broader rhizome scales, acute to attenuate blade apex, commonly two series of areoles between parallel veins,
commonly one sori per areole and hydathodes absent or few evident. Campyloneurum leoniae differs from C. irregulare by more compact and non-pruinose rhizomes, thinner stipes, relatively broader, thinner and more opaque
laminae, and distribution at lower elevations. Campyloneurum madrense is
different to C. angustifolium because it has narrower and darker rhizome
scales with denticulate margin, long scales cells and distributed at lower elevations. Finally, Campylonerum pittieri is here recognized as valid species and it
differs from the similar C. amphostenon by longer rhizomes with appressed
scales that have a patent, long acuminate apices, relative broader laminae,
veins evident and distribution at higher elevations. |
