Polypodiaceae is a family of polypod ferns, which includes more than 60 genera divided into several tribes and containing around 1,000 species. Nearly all are epiphytes, but some are terrestrial.[1]

Description

Stems of Polypodiaceae range from erect to long-creeping. The fronds are entire, pinnatifid, or variously forked or pinnate. The petioles lack stipules. The scaly rhizomes are generally creeping in nature. Polypodiaceae species are found in wet climates, most commonly in rain forests. In temperate zones, most species tend to be epiphytic or epipetric.[1]

Notable examples of ferns in this family include the resurrection fern (Pleopeltis polypodioides) and the golden serpent fern (Phlebodium aureum).[1]

Classification

Polypodiaceae is usually divided into the following subfamilies and tribes. Some are classified by other authorities as separate families.[2]

  • Subfamily Platycerioideae - Fronds with stellate (radiating from central point) hairs. Example genera: Platycerium, Pyrrosia
  • Subfamily Polypodioideae - Possess scales and/or hairs. Never stellate.
  • Tribe Drynarieae - Fronds are dimorphic. Example genera: Drynaria, Aglaomorpha
  • Tribe Selligueeae - Characterized by opaque stem scales. Fronds are monomorphic. Example genus: Selliguea
  • Tribe Lepisoreae - Clathrate (lattice-like) scales. Thick exospore. Fronds monomorphic. Example genera: Belvisia, Lepisorus
  • Tribe Microsoreae - Clathrate scales. Thin exospore. Fronds monomorphic. Example genera: Lecanopteris, Microsorum
  • Tribe Polypodieae - Mostly clathrate scales, but somtimes opaque. Thick exospores, but sometimes thin. Fronds monomorphic. Example genera: Polypodium, Pecluma
  • Tribe Loxogrammeae - Lacks sclerenchyma (supporting tissue) in plant body, except in the roots. Example genus: Loxogramme
