  NationMaster - Encyclopedia: Australian Tree Fern
Australian Tree Fern (Cyathea cooperi), also known as the Lacy Tree Fern, is a medium-to-large, fast growing tree fern native to Australia.
As a new fern frond is formed, it is tightly curled so that the tender growing tip of the frond (and each subdivision of the frond) is protected within a coil.
In the case of many fronds, such as that of the Australian tree fern in the picture at right, long hairs or scales provide additional protection to the growing tips before they are fully uncoiled.

  Tree fern
Tree ferns are found growing in tropical and subtropical areas, including cool to temperate rainforest in Australia, New Zealand and neighbouring regions (eg Malaysia, Lord Howe Island[?] etc).
Like all ferns, tree ferns reproduce by means of spores formed on the undersides of the fronds[?].
If the crown of a tree fern is damaged it will inevitably die because that is where all the new growth occurs (Tree fern trunks rarely fork).

 fern. The Columbia Encyclopedia, Sixth Edition. 2001-05
The ferns and their relatives (e.g., the club moss and horsetail) are the most primitive plants to have developed a true vascular system (see plant).
Ferns reproduce by an alternation of generations (see reproduction), the fern itself being the sporophyte, which produces asexual spores.
In most ferns the sporangia (spore-bearing sacs) are borne in clusters (called sori), which appear as brown dots or streaks on the underside of the leaves.

 TREE FERN
Tree ferns naturally grow in damp conditions and revel in having their trunks soaked at regular intervals.
I have recently given my tree ferns less protection than I used to in winter, I now allow the crown to fill with oak leaves that fall in profusion from a nearby tree in autumn forming an insulating layer to protect the young crosiers.
If you don't have an obliging tree nearby a handful of straw pushed into the crown with the arrival of frost should surfice, but be aware that if the temperature turns really cold you will have to supply additional insulation including the whole trunk, horticultural fleece or similar is normally sufficient.
