In color, texture, and a good deal in form, this Fern has a 
very considerable affinity with our Antropkyum Galeottii 
(Tab. 70); but there are characters present too important to 
allow the two to be considered identical, whether in respect 
to species or even Genus. The form is different, exactly 
lanceolate not at all approaching to lorate (strap-shaped) the 
texture is much more pellucid so that the venation is readily 
distinguishable (which is so indistinct in the Antropkyum as 
to have escaped the notice of some authors.) We have 
already, in describing the Antropkyum Galeottii, spoken of 
the frequent presence of short linear or oblong sori in series, 
as in Grammitis : but such are always nearer the margin than 
the costa, and invariably mixed with branched, if not anas- 
tomosing sori; here, on the other hand, the sori are placed 
nearer the costa than the margin, with great regularity ; and 
though varying in length, always undivided, everything 
indeed indicating the section Loxogramme of the Genus 
Grammitis. This species we name in compliment to Osbert 
Salvin, Esq., who allowed us to share in a beautiful collection 
of F erns he lately collected in Guatemala and Mexico.
