American bird's-nest fern

Asplenium serratum is an epiphytic or lithophytic fern that grows on eroded limestone, tree trunks, rotting stumps, and fallen logs.

Asplenium serratum is native to the tropical Americas, from southern Mexico to Central America, the Caribbean, Florida, northern and western South America, Brazil, and Paraguay to northeastern Argentina. It is rare in central and southern Florida, where it is a state-listed endangered species.
