Tree fern
Tree ferns are found growing in tropical and subtropical areas as well as temperate rainforests in Australia, New Zealand, and other island groups nearby. A few genera extend further, such as Culcita in southern Europe. Like all ferns, tree ferns reproduce by means of spores developed in sporangia on the undersides of the fronds. The fronds of tree ferns are usually very large, and multiple-divided fronds. The young fronds of ferns emerge in coils that uncurl as they grow.
