Pteridophytes are vascular plants and have leaves (known as fronds), roots and sometimes true stems, and tree ferns have full trunks. Examples include ferns, horsetails and club-mosses. Fronds in the largest species of ferns can reach some six meters in length.True ferns grew alongside the big tree-like lycophytes and the horsetails of the Carboniferous Period 300 million years ago and are by far the most diverse pteridophyte group today. They are often found in the tropics, but can grow in temperate forests and are even known from some arid habitats.Ferns are unique in land plants in having two separate living structures, so the ferny plant that we see out in the bush produces spores, and those spores, when they are released, don’t grow straight back into a new ferny plant. They grow into a little tiny plant that we call a gametophyte.
