Are you getting out and about these Christmas holidays? Then we’ve got the ideal FREE gift for you – the eFloraNZ chapter on the scaly tree ferns.
eFloraNZ chapter for Cyathea, the scaly tree ferns. (pdf, 13 MB.)
You’ll find scaly tree ferns almost everywhere in New Zealand where there are forests. They can be superabundant in places.
You can use this eFloraNZ chapter to learn the different scaly tree ferns. Being an authoritative account, the eFloraNZ is a little technical. If that doesn’t suit you, try Te Papa’s online guide to New Zealand’s tree ferns, or get a crowd-sourced identification by uploading photos to the citizen science website NatureWatchNZ.
New Zealand’s scaly tree ferns
Five scaly tree fern species, in the genus Cyathea, are native to mainland New Zealand (although one, Cyathea colensoi, does not produce a trunk!). Another two species are restricted to New Zealand’s Kermadec Islands.
The silver fern, or ponga, is a scaly tree fern, Cyathea dealbata. What presumably equates to a secondary pinna of a frond, albeit with a longer stalk, graces some of the options currently being considered for New Zealand’s flag.
The silver fern is not as widespread through New Zealand as you might think, especially for such a popular icon.

What is the eFloraNZ?
The eFloraNZ (electronic Flora of New Zealand) is a collaboration between Te Papa and Landcare Research. It has made definitive accounts of New Zealand’s land plants available online. While much of the information is outdated, it is being progressively revised.
Publication of the eFloraNZ chapter for the scaly tree ferns means eFloraNZ revisions now encompass all of New Zealand’s tree ferns. The eFloraNZ chapter for the hairy tree ferns, in the genus Dicksonia, was published earlier this year.

Also just published is the eFloraNZ chapter for the Ophioglossaceae ferns, including the parsley ferns, moonworts, and adder’s tongues. Well done if you see one of these – these diminutive ferns are much harder to spot than tree ferns!

The next fern chapter for the eFloraNZ should be the Hymenophyllaceae filmy ferns, which will hopefully be published early-2016. The chapter for the Thelypteridaceae is also in production, while we’re currently drafting the chapter for the Aspleniaceae spleenwort ferns.
