Probably there are few Fern Herbaria, containing various 
suites of specimens, in which the present species of Pteris 
(with free or only forked veins), will not be found mixed and 
confounded with the original Pteris pedata of Linnaeus, a species 
having anastomosing veins, and therefere a Litobrochia , Presl. 
(Doryopteris, J. Sm ., Fee.) ; so closely are they allied in other 
respects : and in the old and opaque specimens, of either kind, 
the venation is very difficult to be seen. The present is, 
indeed, usually a more compound species ; but is often less so 
than is here represented. Desvaux was probably the first to 
distinguish the two, but Baddi’s name is surely to be preferred 
to his. The above localities may be entirely depended on, 
as they are derived from specimens existing in my Herbarium.
