Tree ferns. Understorey of a temperate rainforest showing the growth of tree ferns (upper left,lower right) with their crowns of leaf fronds. 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. Photographed in the Julius River Forest Reserve,Tasmania | |
