 | | However, the plants formally known as tree ferns comprise a group of large ferns belonging to the families Dicksoniaceae and Cyatheaceae in the order Cyatheales. |
 | | Tree ferns are found growing in tropical and subtropical areas, including cool to temperate rainforests in Australia, New Zealand, Malaysia, Lord Howe Island, 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. |
