Phlebodium aureum (golden polypody, golden serpent fern, cabbage palm fern, gold-foot fern, hare-foot fern;syn. Polypodium aureum, Polypodium leucotomos) is an epiphytic fern native to tropical and subtropical regions of the Americas. It is confined to the eastern side of the continents, extending north into the United States to Florida and the extreme southeast of Georgia, and south through the Caribbean (the Bahamas, Puerto Rico, and Lesser Antilles), and northern and eastern South America to Paraguay. It is the only species of Phlebodium found in North America, the other species all confined to South America. Other common names include calaguala (Spanish language), laua`e haole (Hawaiian),samambaia (Portuguese), and hartassbräken (Swedish).
It is a rhizomatous fern, with the creeping rhizome 8–15 mm (rarely 30 mm) in diameter, densely covered in the golden-brown scales that give the species its name. The fronds are large and pinnatifid (deeply lobed), from 30–130 cm long and 10–50 cm broad, with up to 35 pinnae; they vary in color from bright green to glaucous green and have undulate margins. Several round sori run along each side of the pinna midrib, and the minute spores are wind-dispersed. The fronds are evergreen in areas with year-round rainfall, semi-evergreen or briefly deciduous in areas with a marked dry season.
