Genus Acrostichum is a type of fern that is commonly found in wet habitats like swamps, marshes, and floodplains. Its scientific name is derived from the Greek word "acros," which means "top," and "stichos," which means "line." There are several synonyms for the term "genus Acrostichum," including "leather fern," "shoestring fern," "file fern," and "giant leather fern." These synonyms refer to the plant's tough, leathery fronds that grow in a linear pattern along the stem. Additionally, the genus is sometimes confused with the unrelated "Boston fern" or Nephrolepis exaltata, which is also commonly used as a houseplant.
