Laua'e, or Microsorum scolopendria, is a naturalized fern, first observed in the early 1900's. It is also known as maile-scented fern, and is found throughout the main islands, often used as a border plant in landscaping.
The true laua'e fern, Microsorum spectrum, once used in hula adornments, is now rare. The Wainiha Valley on Kaua'i has the largest population of the fern, and is now part of a 7,050-acre preserve. The naturalized laua'e now replaces it in hula adornments.
