Japanese False Spleenwort (Deparia petersenii)

The Japanese False Spleenwort, scientifically known as Deparia petersenii, is a fern with a presence in both natural and cultivated settings. Read on to discover more about its characteristics, distribution, and ecological impact.

Considerations for Pets

  • This plant has been noted as potentially accumulating certain elements (PB, Cd, Cu, Zn) in its tissues. This process of Hyperaccumulation, along with its presence in gardens, might be relevant for pet owners.

Considerations for Children

  • This plant has been noted as potentially accumulating certain elements (PB, Cd, Cu, Zn) in its tissues. This process of Hyperaccumulation, along with its presence in gardens, might be relevant for child safety.

Nomenclature and Taxonomy

  • Scientific Name: Deparia petersenii (Kunze) M. Kato
  • Common Name: Japanese False Spleenwort
  • Family: Dryopteriaceae (also mentioned as Aspleniaceae)
  • Synonym: Deparia petersonii (Kunze) M.
  • Other Common Names: Petersen's-Spleenwort, Japanese Lady Fern
  • Taxonomic Rank: Species

Distribution and Habitat

  • Native to Asia, including southern Honshu, Japan.
  • Found in bottoms of ravines and on walls.
  • Has been found in the Everglades.

Ecological Role

  • Considered an exotic and invasive species in some regions, such as Savannah, GA, and potentially Wisconsin.

Morphological Characteristics

  • A forb/herb, which is a non-woody plant that is not a grass.
  • Blade ovate-lanceolate, abruptly narrowed to an acuminate, pinnatifid apex (according to Flora of North America).
  • Forms a leafy clump with a tall, soft green color.

Quirky Facts

  • Deparia petersenii is a hyperaccumulator, meaning it can accumulate high concentrations of certain elements (PB, Cd, Cu, Zn) in its tissues. This characteristic has implications for phytoremediation and environmental studies.

Interactions with Other Organisms

  • Mentioned alongside other invasive species, such as Japanese honeysuckle and Japanese climbing fern.
