Fern

Ferns (Polypodiopsida or Polypodiophyta) are a group of vascular plants (land plants with vascular tissues such as xylem and phloem) that reproduce via spores and have neither seeds nor flowers. They differ from non-vascular plants (mosses, hornworts and liverworts) by having specialized transport bundles that conduct water and nutrients from and to the roots, as well as life cycles in which the branched sporophyte is the dominant phase. Ferns have leaves called megaphylls that are more complex than the microphylls of clubmosses.

Horisme est un genre de lépidoptères (papillons) de la famille des Geometridae.
