We have just described a new species of Tmesipteris fork fern. Fork ferns are odd looking and only distantly related to other ferns. We now recognise five species in New Zealand. There are only about 15 species around the world, with Australasia their strong-hold. The new species has been named Tmesipteris horomaka. It is only… Read more »

During my recent visit to Victoria’s Alpine National Park in Australia, I was interested to see a number of familiar plants amongst the unfamiliar gum trees. Searching Victoria’s Alpine National Park for Asplenium hookerianum. Do you recognise any of these? A harder one to finish off. Answers: 1. Acaena novae-zelandiae, bidibidi, piripiri.  A species indigenous to… Read more »

From our search in Victoria’s Alpine National Park, we suspect the rare Asplenium hookerianum (Hooker’s spleenwort) is actually much more common there than previously recognised. But more searching is needed to confirm this.  Searching for Asplenium hookerianum in Victoria’s Alpine National Park.  Asplenium hookerianum can be distinguished from the other ferns it occurs with in… Read more »

While visiting family in Melbourne, I took the opportunity to go fern hunting. Asplenium hookerianum is a rare fern in Australia.  With Melbourne University’s Daniel Ohlsen and Mike Bayly, we went searching for the two populations recorded from Victoria’s Alpine National Park. How to recognise Asplenium hookerianum in Victoria. We were successful, relocating the known… Read more »

Baby ferns

A spot in my garden is being colonised by baby ferns. The toppling of a gum tree last year created bare ground. After a few months, this has now been smothered by little ferns, the biggest only a few cm long. Baby ferns are difficult to identify, but I suspect these are water fern (Histiopteris… Read more »

I was out last week with Tim Park from the regional council looking for Pseudopanax hybrids between lancewood and coastal five-finger near Porirua.    Coastal five-finger and the hybrids are weeds in the Wellington region. Previous post on lancewood and coastal five-finger hybridisation. We spotted a couple of other weedy natives – New Zealand species that… Read more »

I was recently in New Plymouth, where I took the opportunity to visit Pukekura Park. Aside from its lovely cricket ground, the Park is of course notable for its plants. Pukekura Park website. One of the botanical highlights for me was king fern, probably best seen at the Park in the appropriately named King Fern… Read more »

Talking Australian Plants

  • Grevellia acanthifolia. Beautiful.
  • A Stylidium trigger-plant.
  • The parasitic orchid Dipodium.
  • This rare Gingidia species occurs near Armidale. The genus, a member of the carrot family, is otherwise confined to New Zealand.

I’m just back from the Australian Systematic Botany Society’s conference, followed by three days working in the herbarium of Sydney’s Botanic Gardens. Conference.  The conference involved three days of talks about the evolution and taxonomy of plants. I presented our recent work on the hen & chickens ferns. I found the response interesting, including several… Read more »
