Množina: ferns
ETYM AS. fearn; akin to Dutch varen, German farn, farn kraut; cf. Skr. parna wing, feather, leaf, sort of plant, or Lith. papartis fern.
Any of numerous flowerless and seedless vascular plants having true roots from a rhizome and fronds that uncurl upward; reproduce by spores.
Plant of the class Filicineae, related to gymnosperms and angiosperms; however, ferns reproduce by spores and not seed. Most are perennial, spreading by low-growing roots. The leaves, known as fronds, vary widely in size and shape. Some taller types, such as tree-ferns, grow in the tropics. There are over 7,000 species.
Common forms include polypody (Polypodium); shield fern (Polystichum); maidenhair (Adiantum capillus-veneris); and bracken (Pteridium), a common weed.

paprat
IPA: / paprat /Biljka bescvetnica. Paprati su omiljene dekorativne biljke koje uspevaju u hladu i na suncu, u šumi, vrtu, ali i u sobi. Ima ih više od 9000 vrsta i sve vode poreklo još iz trijasa iz ere krede. U prastaro doba paprati su rasle u obliku ogromnog drveća koje je pokrivalo velike površine. Tada su bili hrana dinosaurusima. Od ostataka tih ogromnih paprati nastao je ugalj. Danas u Australiji raste vrsta paprati čije stablo dostiže visinu i do 25 metara.
