New Caledonian plants

  • Another threat to New Caledonia’s vegetation is browsing by introduced deer and pigs. Conservation International are trialling using the amount of browse on the fern Orthiopteris firma to monitor the effectiveness of animal control projects. Photo Leon Perrie. © Te Papa.
  • New Caledonia has a higher GDP per capita than New Zealand, principally due to nickel and copper mining. Mining operations are widely evident. Photo Leon Perrie. © Te Papa.
  • The large areas covered by Melaleuca trees are very reminiscent of Australia. But they are also testament to one of the major threats to New Caledonia’s vegetation – fire. The fern Dicranopteris linearis flourishes amongst the Melaleuca regeneration. Photo Leon Perrie. © Te Papa.
  • As I knelt to collect a fern, I was stunned to find myself surrounded by pitcher plants, Nepenthes vieillardii. The ‘pitchers’ are traps for catching insects. Photo Leon Perrie. © Te Papa.

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 »

Te Papa’s collection of pressed, dried plant specimens includes samples of native and exotic species collected in New Zealand and other parts of the world. Many of the foreign specimens currently in the collection were brought into New Zealand in the late 1870s to be used as reference material and to assist with the identification of… Read more »

Going International, Part II – What caught my eye at two recent botany meetings

Here are just a few of the many highlights from the two international botany conferences I recently attended: Botany 2012 (Columbus, OH, USA) and  Biodiversity and Evolutionary Biology 2012 (German Botanical Society 21st International Symposium, Mainz, Germany). Plant identification goes visual, interactive and mobile Plant identification keys are useful when you want to identify an… Read more »

Hoards but not seen – the Tanaidacea Knowledge of a significant but seldom heard of group of crustaceans is getting a fresh boost. In its Crustacea section Te Papa has a good collection of New Zealand tanaids (tar-nay-ids) or ‘tanaidaceans’ (tar-nay-iday-see-ans). Tanaids are little marine crustaceans, mostly 2 – 5 millimetres long fully grown (see… Read more »

Going International

This is a recent photo of me (Heidi Meudt) taken here in Oldenburg. I will sign off in German by saying: Auf wiedersehen, bis bald! Photo by Mauricio Lopez.

Back in July, I attended the 2012 Botany Conference, which was held in Columbus, OH, USA, and later this month, I will attend the “Biodiversity and Evolutionary Biology” meeting of the German Botanical Society (DBG) in Mainz, Germany.  Why so much international travel, you may ask, and why is it important to Te Papa and… Read more »

Rare forget-me-nots discovered in the mountains of the South Island

Today, two rare species of forget-me-nots have been added to the Flora of New Zealand. These new species were discovered during an expedition I led to Kahurangi National Park, one of the hotspot for forget-me-nots diversity in New Zealand. These new species, Myosotis chaffeyorum (Chaffey’s Forget-me-not) and Myosotis mooreana (Moore’s forget-me-not) are described and illustrated in an article published today… Read more »
