This Genus, well distinguished by the naked globose sori, and pecnliar nervation, together
with a certain natural character, is divided into two groups by Presl.
§ I. Vena ntrinque infima in arcum anastomosans ; venula ex apice anguli in sinum
laciniarum frondis excurrens ;—comprising about 20 species.
§ II. Venæ utrinque inferiores plures (duo-tres-quatuor) in arcus anastomosantes, venula
ex apice anguli in sinum arcus superioris excurrente vel subinde libera, ilia ex ángulo
supremo in sinum laciniarum frondis excurrente to which belongs our present species,
and, according to Presl, about 8 others.
