An order of cryptogamous plants, the Filices, which have their fructification on the back of the fronds or leaves. They are usually found in humid soil, sometimes grow epiphytically on trees, and in tropical climates often attain a gigantic size.
In damp places in woods, ravines, and rocky crevices grow the feathery green ferns. They may be recognized by the shape of their leaves, known as fronds. These have a single midrib, with small leaflets branching off from either side. The leaflets may be delicately cut into toothed or lobed edges. Most of the familiar ferns grow from a creeping underground stem called a rootstock.
A vascular plant bearing spores (rather than seeds), with flattened leaflike "fronds" further divided. Some flowering plants (Achillea, yarrow; Conium maculatum, poison-hemlock; and the common house plant "asparagus fern," for example) have leaves which superficially resemble ferns, but they are, in fact, flowering plants and not ferns.
a type of plant with large, divided leaves. First found in the Devonian. During the Palaeozoic era tree-ferns, some up to several metres in height, dominated the forest vegetation. Today ferns grow mostly as smaller plants and tree ferns are rare.
Ferns are non-flowering vascular plants with rhizomes that were plentiful during the Mesozoic Era and usually live in warm, moist areas. Ferns have fronds divided into leaflets. Classification: Plyla: Lycophyta (lower ferns like clubmosses), Pterophyta (ferns), Psilophyta (whisk ferns) (true ferns belong to the Class Filices).
A fern is any one of a group of about 20,000 species of plants classified in the phylum or division Pteridophyta, also known as Filicophyta. The group is also referred to as polypodiophyta, or polypodiopsida when treated as a subdivision of tracheophyta (vascular plants). The study of ferns is called pteridology; one who studies ferns is called a pteridologist.
A Web based Gnutella servant for people with special requirements on a Gnutella client. It is essentially a bunch of Servlets, JSP pages and a slightly modified version of an up to date LimeWire core. Check out the Fern homepage for more info.
FERN, the Forests and the European Union Resource Network, is an international non-governmental organization created in 1995 to keep track of the EUâ€™s involvement in forests and to co-ordinate NGO activities at the European level. Through its work, FERN aims to increase the political and economic opportunities for people to create a more balanced society in which human rights are fully respected and environmental and social values are fully integrated.
