Dryopteris crinalis is a species of fern known as the serpent woodfern. It is endemic to Hawaii, where it is known from the main islands. [1]
There are at least two varieties. The var. podosorus was federally listed as an endangered species of the United States in 2010. [2] There are three populations on Kauai, for a total of no more than 47 individual plants. The fern grows on walls of basalt in wet forests. [2] Fronds grow up to 3 ft (0.91 m) long. [3]
