Comprehensive Description

Description

Very small to medium-sized ferns; epiphytic, lithophytic or rarely terrestrial. Rhizome short- or long-creeping or climbing, laterally branched; roots formed ventrally, dorsally with 2 rows of frond scars. Fronds mono-, hemi- or dimorphic, articulated or not; stipe short or long; lamina simple to 2-pinnatifid, entire or shallowly crenate; veins free or anastomosing. Indumentum composed of scales on the rhizome, axes and lamina and hairs on the lamina surfaces. Sori circular (in ours), superficial or slightly sunken, scattered or in a single row on either side of the primary or secondary vein, with or without paraphyses; exindusiate.

Polypodiaceae

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. Drynariaceae, Grammitidaceae, Gymnogrammitidaceae, Loxogrammaceae, Platyceriaceae and Pleurisoriopsidaceae are nowadays usually included in the Polypodiaceae.

Their stems 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.

Notable examples of ferns in this family include:
