Genus Peltiphyllum is a botanical group of plants commonly known as shield ferns. However, there are several other synonyms that are used interchangeably to refer to this particular genus. These include the names Peltiger, Peltipteris, and Pellaea. All of these names are derived from the Greek word "pelta," meaning shield, which refers to the distinctive shape of the fern's fronds. Shield ferns are widely distributed throughout the world, with most species found in the Americas and Asia. They are characterized by their evergreen foliage, which consists of narrow, lance-shaped leaves that grow in a rosette-like pattern. The plants produce spores on the underside of their leaves, which are used for reproduction.
