A fern is a plant that has long stems with feathery leaves and no flowers. There are many types of fern. a type of plant with green leaves shaped like large feathers, but no flowers. Any of about 10,000-12,000 species (division Filicophyta) of nonflowering vascular plants that have true roots, stems, and complex leaves and reproduce by spores. Though ferns were once classified with the primitive horsetails and club mosses, botanists have since made a clear distinction between the scalelike, one-veined leaves of those plants and the more complexly veined fronds of the ferns, which are more closely related to the leaves of seed plants. Ferns come in a wide variety of sizes and shapes. Many are small, fragile plants; others are treelike (see tree fern). The life cycle is characterized by an alternation of generations between the mature, fronded form (the sporophyte) familiar in greenhouses and gardens and the form that strongly resembles a moss or liverwort (the gametophyte). Ferns are popular houseplants

any of numerous flowerless and seedless vascular plants having true roots from a rhizome and fronds that uncurl upward; reproduce by spores
