PLUS pages of each of the magnified treefern sori scans I've none so far for those that might like to compare the differences without having to skip back and forth.

PLUS pictures of my fernery with links to other pages about the ferns and other plants I am growing, and techniques for propagating ferns from spore.

Complete list of all species of Cyathea referred to in this site, including names which are no longer current, and regions where each is found.




DISTRIBUTION DATA - Listing of all species of Cyathea in each region and details of countries or island groups where each species is found.
KEYS - keys to the subdivision of the genus Cyathea in each region, followed by the keys to the species (where needed) in each country or island group in the region.
(While there are probably more easily observed features to distinguish many species in the field - the need in many cases to examine specimens with a microscope is limiting, although Pocket Microscopes are available - hopefully these keys may be better than nothing for any treefern enthusiasts visiting these regions!)

With some 83 species of Cyathea in New Guinea, rather than attempting to produce a key for these, the following web site may prove useful (for many other fern genera as well)    <>

Australian National Botanic Gardens Website has a couple of sections relating to treeferns, including

          <> with photographs of numerous Australian native ferns, including some of treeferns (even though some are incorrectly named .... far be it for me to correct the ANBG but C. cunninghamii is not recorded from Carnarvon Gorge (these are almost certainly C. cooperi) and C. brownii is not found at Minnamurra Falls on the mainland (again possibly C. cooperi)

I have briefly described here some of my favourite places, mainly in Victoria (Australia), where treeferns can be seen growing, either in cultivation or in the wild. In time I hope to add more extensive treefern lists and photos to these pages.
A fond farewell to all who have made use of this web site over the past couple of years. Unfortunately I have recently been diagnosed with pleural mesothelioma (cancer of the lung lining) and in the last couple of weeks this has become quite aggressive. With only days left now, the updates I am making to the site today will be the last. My thanks to all those who have sent E-mails congratulating me on my site ... it has given me a lot of pleasure working on it and communicating with other treefern lovers.
