Discusión taxonómica
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.A
