Taxonomy
One of the groups treated most persistently as a distinct genus, mainly on account of the non-dimidiate, basally articulate pinnules. Other characters are the short-creeping rhizome, sclerotic axes, continuous sori, free veins, and trilete spores. The species of this section were in the past often placed in the genus Schizoloma, together with the species lacking dimidiate pinnules of sect. Schizoloma as treated here; but the resemblance is only a negative one.
