I’ve recently learnt that the introduced Azolla pinnata (ferny azolla) has been found in the Wellington region. I’m interested in its distribution and would be grateful for help in looking for more. Azolla plants are fairly easy to spot: look for a red plant covering still bodies of water. Azolla are ferns, believe it or… Read more »

Where would you go to find a new species? Perhaps somewhere remote and little-visited, especially if it is ecologically unusual – New Caledonia maybe… Well, instead, how about inside Te Papa’s collections, because that’s where I first discovered a new species of Gleichenia tangle fern. A lot of biodiversity remains to be documented, particularly amongst… Read more »
You’ll never have seen anything like these New Caledonia ferns in New Zealand, unless you’ve been to a very interesting garden (which I’d love an invitation to!). These are photos from my recent fern collecting trip.
A lot of New Caledonian species belong to fern genera that also occur in New Zealand. Some look very similar to New Zealand species, whereas others are quite different! Here’s a few from my recent trip.
About 35 species of fern are found in both New Caledonia and New Zealand. That’s about 13% and 18% of the total species in each area. Almost all of these are widespread species that are also found elsewhere in the Pacific (and beyond). Here’s a few of them that I saw during my recent field… Read more »
Below are photos of some of the botanical/landscape highlights from the recent expedition to New Caledonia that I participated in. But first, a bit of background: New Zealand and New Caledonia both sit on the (largely) submerged continent Zealandia, which separated from Australia and the rest of Gondwana some 60-80 million years ago.

USA fern taxonomists have created a minor stir after re-classifying a group of central American ferns into a new genus named Gaga, after the singer Lady Gaga. Abstract of the article formally naming the new genus Gaga. Youtube video of the taxonomists discussing their research. The researchers say the naming for Lady Gaga was in… Read more »
I’m just back from three weeks collecting ferns in New Caledonia. For a place so close to New Zealand (shorter flight time than to Australia), I knew very little about New Caledonia. I expect that is true for many New Zealanders, and it presumably reflects our very different cultures, not least being the language difference… Read more »
On Saturday I joined the Wellington Botanical Society’s field trip to Wright Hill in Karori, Wellington. Wellington city would not be my first choice of locality for fern spotting, but we still found plenty to keep me interested. The filmy ferns Hymenophyllum flexuosum and Trichomanes endlicherianum are always pleasing finds. Although widespread, they are not… Read more »
I recently had an enquiry from someone who noticed during the middle of the night that their pile of split firewood was emitting a faint glow. What could cause this?! Apparently there are fungi that grow in rotting wood that can emit light through luminescence. The phenomenon is sometimes called “foxfire”. I’ve never noticed this… Read more »
