Arthropteris climbing ferns

Arthropteris_tenella_climbing_reduced

I’m a co-author of a just-published scientific paper examining the evolution and classification of the Arthropteris climbing ferns. The paper was a real international collaboration, involving authors from China, Netherlands, France, United Kingdom, and New Zealand. It is unclear how many species there are of Arthropteris – probably somewhere between 10 and 20. They occur… Read more »

The long-and-short of lycophytes

I don’t do plant-free holidays, and one of the species I wanted to photograph during my recent Northland holiday was the tiny and rare Phylloglossum drummondii. This diminutive plant has a Nationally Critical conservation ranking, because of its low numbers and the destruction of its swamp habitat. Finding it necessitates a winter (or early spring) field trip,… Read more »

Banks’ black and white engravings – now imaged and online!

Brachyglottis repanda Forster & G. Forster, 1895 Parkinson. A common coastal, forest and lower montane New Zealand species.

  It took many hours of sorting, registration, taxonomy review, preparation and coordination, then 12 long sessions in the imaging lab.  Te Papa Science staff have now completed the online access for 2241 black & white engravings of plants collected on Captain Cook’s first voyage. The Te Papa Collection Online narratives about the Banks and Solander black and white engravings… Read more »

Re-planting New Zealand

In regard to Bob Brockie’s recent article in the Dominion Post (24 June 2013, page A8), here is some rationale for viewpoints about plants that some commentators have teasingly called “eco-fascism”. Instead, they are logical expressions about the conservation of New Zealand’s biota and ecosystems, including their genetic integrity. For any effort claiming to be… Read more »

New Zealand plants abroad part 2: the troublemakers.

My previous blog featured New Zealand native plants that are cultivated overseas. However, some of our native plants, including many of the species I recently saw in UK gardens, have gone ‘rogue’ and are considered invasive species in some countries. For example our pohutukawa (New Zealand Christmas tree; Metrosideros excelsa) is invading parts of South… Read more »

For the love of birds

NZ Birds Online screenshot - Tiny forest birds

We have recently launched NZ Birds Online, an encyclopaedia of New Zealand birds. I have been involved in this project for 18 months, from the IT side of things, and it’s been an absolute pleasure all along! I’m an identification geek (among other geekily obsessions). If I have taken a photo of a fern, or… Read more »

Learn ferns in Wellington, 2

Are you interested in learning more about ferns, and in the Wellington region? The talk in March was so popular that Otari have asked me back for round two.  I’ll lead a walking-talk through the fernery at the wonderful Otari-Wilton’s Bush, Sunday 23rd June 2013, beginning 2pm from the Otari Information Centre. Interested in learning… Read more »

Whilst recently holidaying in Bristol in the UK I was amazed at the abundance and variety of ferns growing on the stone walls around the city.  The spleenwort or Asplenium ferns seem to be the most common ferns of this habitat. This genus also occurs in New Zealand and includes our hen and chickens fern. … Read more »
