Var. frondòsa has its fronds partly sterile below and irregularly fertile towards the summit.
Var. incìsa has the inner pinnules of some of the pinnæ more or less cut-toothed.
Var. glandulòsa has glandular hairs on the pinnæ, rachis and even the stipes of the sterile frond. This is known only on the coastal plain from Rhode Island to Maryland.
