With examples - Garden Bagan The fossil plant Elkinsia polymorpha, a "seed fern" from the Devonian periodabout 400 million years agois considered the earliest seed plant known to date.Seed ferns (Figure 26.3) produced their seeds along their branches, in structures called cupules that enclosed and protected the ovulethe female gametophyte and associated tissueswhich develops into a . In the context of modern phylogenetic models,[8] the groups often referred to as pteridosperms appear to be liberally spread across a range of clades, and many palaeobotanists today would regard pteridosperms as little more than a paraphyletic 'grade-group' with no common lineage. Not only is this good for the environment, it saves time and money. They are formed in structures called archegonia or antheridia. The fertilized egg remains attached to the prothallus. They are also safer for the plants. Asexual methods of reproduction include apogamy, poliferous frond tips, and rhizome spreading. Northern window ideal. Ball Horticultural Advantages of self-fertilization are that fewer spores are wasted, no external gamete carrier is required, and organisms adapted to their environment can maintain their traits. Good for beginners because of ease of culture. A Carboniferous seed fern from Western Europe and North America, Lyginopteris oldhamium, evolved one of the earliest scrambling and climbing morphologies by coupling highly conductive woody xylem with a distinctive striped cortex that acted as a mechanical collar (Figure 2 (d)), allowing its stems to bend and flex under mechanical stress (Massel.

Hoshizaki, B. J., 1975. The concept of pteridosperms goes back to the late 19th century when palaeobotanists came to realise that many Carboniferous fossils resembling fern fronds had anatomical features more reminiscent of the modern-day seed plants, the cycads. In the presence of water, a sperm uses its flagella to swim towards an archegonium, attracted by chemical signals. In apogamy, a sporophyte grows into a gametophyte without fertilization occurring.Ferns use this method of reproduction when conditions are too dry to permit fertilization. However, unlike flowering plants, ferns do not have flowers or seeds; instead, they usually reproduce sexually by tiny spores or sometimes can reproduce vegetatively, as exemplified by the walking fern. With their interesting foliage and textures, ferns are easy to grow and require little maintenance. If there is enough moisture, the gametophyte is fertilized and grows into a diploid sporophyte. Bracken ferns ultra-light spores helped distribute the species across the globe. The best time for dividing outdoor ferns is after the first frost through November.

Comments: So-called "soilless" potting mixtures, commonly used by commercial greenhouse growers, are quite satisfactory for potting ferns. In a haploid plant, each cell contains one set of chromosomes or half the genetic complement (like a human sperm or egg cell). Many ferns are known for their lacy appearance, these ferns have fronds that are even further divided. This tree-like growth is not exclusive to one group within Cyatheales, and many groups also contain more typical looking ferns. Details for both are given under the sections "Dividing" and "Potting.".

One of the largest fern families, Dryopteridaceae contains many diverse genera including Elaphoglossum, Polystichum, and Dryopteris. 3-pinnate (tripinnate): fronds are divided three times. The life cycle is unusual because it consists of two distinct generations of two different plants. The number of known extant fern species is about 10,500, but estimates have ranged as high as 15,000, the number varying because certain groups are as yet poorly studied and because new species are still being found in unexplored .

Ferns with creeping rhizomes spread as the rhizome grows above or below the substrate. The presence of honeydew, a sticky syruplike material on the foliage, is an indication of fern scales or other insects. In a sense, this is true, but the tiny plantlets that emerge from spores are genetically different from adult ferns. Soil Mix: One-third potting soil, one-third peat moss, one-third sand, gravel and charcoal (in equal parts).
