From Wikipedia, the free encyclopedia
Marsilea villosa, the ‘ihi‘ihi (Hawaiian) or villous waterclover (English), is a species of fern with leaves resembling four-leaf clover. Native to the Hawaiian islands of Oahu, Molokai and Niihau, it is found exclusively in areas with irregular flooding. Fewer than 2,000 individual plants in four populations remain and the plant was federally listed as an endangered species in 1992.
M. villosa releases its spores during floods, but requires the waters to subside for new plants to become established.
