Tree fern. Close-up of young curled leaves of a tree fern. As they mature the leaves will unfurl and open. Tree ferns are among the most primitive plants still alive on Earth. They dominated the first forests over 300 million years ago,before flowering plants evolved. Modern species are largely confined to tropical climates,where some reach heights of 20 metres.
