Asplenium serratum is found rarely in southern peninsular Florida, where it is at the extreme edge of its tropical American range. This large simple-leaved spleenwort is called "American bird's-nest fern" because of its superficial resemblance to the Old World A . nidus Linnaeus, which is regularly grown in temperate conservatories. Asplenium serratum is unusual in having roots with abundant, matted hairs rather than scattered hairs as found in other species.
