Probably there are few Fern Herbaria, containing various 
suites ‘of specimens, in which the present species of Pteris 
the venation is very difficult to be seen. The present is, 
d, a more compound species; but is often less so 
than is here represented. Desvaux was probably the first to 
distinguish the two, but Raddi’s name is surely to be preferred 
to his. The above localities may be dlitinely depended on, 
as they are derived from specimens existing in my Herbarium.
