Doryopteris palmata is distinguished from D. concolor by the
netted veins, puberulent stipe, and buds at the base of the blade.
Doryopteris pedata, under which D. palmata has often been
treated as a variety (e.g., by Tryon, 1942) is limited to the Greater
and Lesser Antilles and differs in lacking proliferous buds.
