One hundred and one species of ferns and allied plants (pteridophytes) have been recorded from the Tasmanian mainland and offshore islands. While some two-thirds of these are readily recognised terrestrial, epiphytic or lithophytic ferns of forests and fern gullies, some are lesser known species of more specialised habitats. This book records the ecology and distribution (with maps) of all Tasmanian pteridophytes. In addition, there are field keys for all Tasmanian genera and species, and all species are illustrated in colour. Conservation issues are also addressed.
