West Coast Fern Fieldwork 2012, 1 – what we were doing

Gleichenia ferns often grow entangled with one another and with other plants; hence their common name of tangle ferns.  But our understanding of them is also in a tangle.  Two or three species are currently recognised in New Zealand, but I think there are at least five.  The picture is of a new species.  It looks similar to the others from above, but very different when viewed from below.  I hope to formally describe it in a year or so.  Then I will be able to show you the differences.  Our fieldwork significantly extended the known occurrences of this fern.  Photo Leon Perrie. © Te Papa.

I’m just back from 10 days collecting ferns in the South Island’s West Coast. From previous collections, we knew of several currently unrecognised species of fern that occur on the West Coast. We investigated these records, visiting the sites to collect more material for our studies and to assess the plants in the field, including… Read more »

Common ferns

Hound's tongue fern, Microsorum pustulatum.

Would you like to learn to recognise some of New Zealand’s ferns? “Fernland” was an early colloquial name for New Zealand, so it’s almost patriotic to be able to recognise a few of the country’s ferns! I’ve put together notes and images for 13 common species, showing how to distinguish them and where you might find… Read more »

A new fern, Lastreopsis kermadecensis

Te Papa Research Fellow Patrick Brownsey and I have just described a new species of fern, Lastreopsis kermadecensis.  It only occurs on Raoul Island, which is the largest island in the Kermadec Islands group.  Hence, the second part of the new species name! The Kermadec Islands are the most northern part of the New Zealand… Read more »

Plant Hunt at Hokio, Levin

Te Papa Research Fellow Patrick Brownsey was recently contacted about a population near Levin of the very rare Ophioglossum petiolatum. Ophioglossum are odd looking ferns, as befits a common name of “adder’s tongue ferns”.  We don’t have a picture of O. petiolatum (stalked adder’s tongue fern), but the related O. coriaceum is similar; O. petiolatum… Read more »

A highlight of our Fijian expedition was a trip to Kadavu, a medium-sized island south of Viti Levu.  Kadavu is a priority for Conservation International.  Four species of bird occur there and nowhere else in the world.  However, little is known of Kadavu’s bryophytes, lichens, and ferns, and it was our job to find out. While… Read more »

Ferning in Fiji

I’m lucky to have escaped the end of the New Zealand winter with a work trip to Fiji. This was as part of a Conservation International-funded, international expedition. The trip was led by Matt von Konrat of Chicago’s Field Museum, with local logistics coordinated by Marika Tuiwawa and Alivereti Naikatini of the University of the… Read more »
