Ferns
The most familiar of all woodland ferns, found the world over, is Pteridium aquilinum, the common bracken brackenor brake,common name for a tall fern (Pteridium aquilinum) with large triangular fronds, widespread throughout the world, often as a weed. 1. any tracheophyte plant of the phylum Filicinophyta, having roots, stems, and fronds and reproducing by spores formed in structures (sori) on the fronds. 2. any of certain similar but unrelated plants, such as the sweet fern. True mosses are nonvascular plants whose most commonly recognized life form is a gametophyte, and true rushes are grasslike flowering plants. Instead, these common names indicate that the club mosses and spike mosses are often small plants that hug the ground, and scouring rushes have long, grasslike stems. Fern leaves used in floral arrangements are a major industry in Florida, and in some cultures tree fern stems are used to make elegant, naturally sculpted bowls. The contrasting colors of the vascular tissue in the stems and leaf bases of these plants create complex and pleasing designs. This is a conspicuous group of woody plants commonly known as the conifers. The members of this group produce ovules that mature into seeds. These ovules and seeds are found on the upper surfaces of scale structures which often are clustered into cones.  Psilotophyta. Return to phylum directory. Group consisting of two extant genera, Psilotum and Tmesipteris, in one family, Psilotaceae. These plants are primitive in structure: Psilotum lacks both roots and leaves and is structurally similar to the fossil genus Rhynia.. Class Filicopsida, the true ferns, approximately 10,000 species. * The common names mosses and rushes applied to these species do not mean that these groups are related to the mosses and rushes, any more than a pineapple is related to pines or a breadfruit has some affinity to wheat. Fern leaves used in floral arrangements are a major industry in Florida, and in some cultures tree fern stems are used to make elegant, naturally sculpted bowls. The contrasting colors of the vascular tissue in the stems and leaf bases of these plants create complex and pleasing designs. Pteridophtyes are a phylum of plants. They are the vascular plants (those having xylem and phloem tissues) that reproduce by releasing spores rather than seeds, and they include the highly diverse true ferns and other graceful, primarily forest-dwelling plants. Fern leaves used in floral arrangements are a major industry in Florida, and in some cultures tree fern stems are used to make elegant, naturally sculpted bowls. The contrasting colors of the vascular tissue in the stems and leaf bases of these plants create complex and pleasing designs. Return to phylum directory. The phylum Pterophyta is a group of non-seed plants with a fossil record dating back to the lower Devonian. The phylum consists of about 11,000 living species. Vegetatatively ,the Pterophyta are a diverse group of plants with true leaves, roots and stems. Leaves are macrophylls and, in many families, demonstrate circinate vernation (a pattern of uncoiling of a crozier-like structure due to uneven growth).  All pteridophytes have a true alternation of generations, in which a dominant sporophyte generation produces spores through meiosis, and a free-living gametophyte generation forms gametes (egg and sperm) by mitosis. Ferns can be used to illustrate the life cycle stages common to all pteridophytes. Fern leaves used in floral arrangements are a major industry in Florida, and in some cultures tree fern stems are used to make elegant, naturally sculpted bowls. The contrasting colors of the vascular tissue in the stems and leaf bases of these plants create complex and pleasing designs. In biology, a phylum (/ˈfaɪləm/ ; plural: phyla) is a taxonomic rank below kingdom and above class. Traditionally, in botany the term division was used instead of phylum, although from 1993 the International Code of Nomenclature for algae, fungi, and plants accepted the designation phylum. The kingdom Animalia contains approximately 35 phyla, Plantae contains 12, and Fungi contains 7. Furthermore, organisms in the stem group of a phylum can possess the body plan of the phylum without all the characteristics necessary to fall within it. This weakens the idea that each of the phyla represents a distinct body plan. fern and shrub sweet fern (see bayberry bayberry,common name for the Myricaceae, a family of trees and shrubs with aromatic foliage, found chiefly in temperate and subtropical regions. The waxy gray berries of the North American wild or cultivated bayberry shrubs (chiefly Myrica cerifera..... 1. any tracheophyte plant of the phylum Filicinophyta, having roots, stems, and fronds and reproducing by spores formed in structures (sori) on the fronds. 2. any of certain similar but unrelated plants, such as the sweet fern.
