71. Vittaria subcoriacea n. sp. 
Rhizomate uti videtur breviter repente, squamis tenuissimis setaceis

latis (ca. 8) breviter stipitatis, i. e., lamina in stipitem 3 ad 5 cm. longam

lata acutiuscula, margine late (2 mm.) reflexo adpresso, in angnlo sorum 
1 mm. latium omnio tegente, soro margineque infra medium folium 
incipiente et ad apicem continuo, nervis facie superiore prominentibus 
fere longis simplicibus va-lde obliquis. Textura suberosa, folio sicco

It is related to P. pusilla (Blume), (Vittaria falcata Kze. ) differing from 
that species in having the soriferous line sunk in an exactly marginal groove, 
that is to say, placed in the thick tissue of the leaf, so that it presents a border 
of sporangia emerging from the groove, while in P. pusilla the sori are arranged 
in an intramarginal groove that does not reach to the border of the frond.
