Acrostichum danaeifolium

A large fern that may grow to eight feet tall, with the fronds alone three to six feet long. The fronds are dark green and shiny. The fertile fronds are cinnamon-colored, resembling suede leather underneath. The fern changes little during the year, but provides a continuous green mass of foliage.

The Seminole use this fern as a febrifuge. The fern fronds are placed in hen nests to kill lice.
