As the Science Collection Manager responsible for managing the botany collection, part of my job is to increase public access to the collection. One way to achieve this is through online narratives. This blog series will highlight some recent botany narratives. In this blog we introduce a significant part of the macro-algae (seaweed) collection – The complete Algae… Read more »

As the Science Collection Manager responsible for managing the botany collection, part of my job is to increase public access to the collection. One way to achieve this is through online narratives. This blog series will highlight some recent botany narratives. In this blog we introduce narrative topics of some recent, very significant, donations to the Te… Read more »

Earlier this year we welcomed Ngāti Toa Rangatira into Te Papa to fill our iwi gallery and to be our iwi in residence for two and a half years. Together with iwi leadership from Ngāti Toa and Te Papa, the exhibition ‘Whiti Te Rā! The Story of Ngāti Toa Rangatira’, and a host of events have been created for you… Read more »

The fascinating flora of Mount Owen, north-west Nelson.

Over the holidays I was fortunate to spend a few days botanising the Marino Mountains, including Mount Owen, in north-west Nelson’s Kahurangi National Park.  Kahurangi National Park  is one of the most botanically interesting regions in New Zealand. Nearly half of New Zealand’s native plant species and 80% of our alpine species are found there…. Read more »

Subantarctic forget-me-not adventures

From the 23rd-30th of December 2013 I was given the opportunity to join Rodney Russ and his team at Heritage Expeditions on board the Spirit of Enderby for a week long adventure to the New Zealand Subantarctic Islands. Link to the Heritage Expeditions website with information about their scholarship The Heritage Expedition Trust awards several… Read more »

How to learn ferns

  • Close up of the scales of Cyathea (left) and the hairs of Dicksonia (right). Photos Leon Perrie, © Te Papa.
  • Trichomanes venosum. In Trichomanes, the reproductive structures are enclosed by a tubular, often trumpet-like structure. Photo Leon Perrie. © Te Papa.
  • Cardiomanes reniforme, kidney fern. More closely related to Hymenophyllum than Trichomanes, although the reproductive structures are at least superficially more similar to the latter. Photo Leon Perrie. © Leon Perrie.
  • Tmesipteris elongata, a fork fern. More closely related to ferns than to seed plants or lycophytes. Nevertheless, the relationship is a distant one, and it doesn’t look very fern like. There are at least five species in New Zealand, and they are usually epiphytic on tree ferns. Photo Leon Perrie. © Te Papa.

Last weekend I was out with the Kapiti-Mana branch of Forest and Bird, giving them an introduction to ferns. A few weeks back, I gave a similar walking-talk at Otari-Wilton’s Bush in Wellington. Many people find ferns an appealing group to learn. Aside from their iconic status in New Zealand, good learning resources are available, and… Read more »

More tangle – a new species of tangle fern

  • Frond underside of Gleichenia inclusisora. The white and flattish frond segments are one of its distinctive features. The undersides of the frond segments of Gleichenia dicarpa are whitish but pouched, while those of Gleichenia microphylla are flat but green. Photo Leon Perrie. © Te Papa
  • Except when very young, the lower stems of Gleichenia inclusisora are usually naked of scales or hairs, in contrast to the other Gleichenia species in New Zealand. Photo Leon Perrie. © Te Papa.
  • All four Gleichenia species presently recognised in New Zealand can grow together, to the extent of intertwining. Gleichenia inclusisora most commonly co-occurs with Gleichenia dicarpa. Gleichenia inclusisora (right) often has a shinier upper-surface, sometimes allowing the two species to be distinguished at a distance. However, this doesn’t always work as well as it does in this photo! Photo Leon Perrie. © Te Papa.
  • Close-up of the frond underside of Gleichenia inclusisora. The reproductive structures (sori) each comprise three sporangia (which produce the spores, the yellow dots) embedded in a pit in the frond. Some empty pits are visible. The distinctive rounded, bicoloured scales can also be seen at top left. Photo Leon Perrie. © Te Papa.

I’d like to introduce a new species of New Zealand fern, Gleichenia inclusisora. Our scientific description was published just before Christmas 2012. The recognition of this species edges the number of native New Zealand fern and lycophyte species nearly to 200. Abstract of paper describing Gleichenia inclusisora.

Wellington Botanical Society Bulletin 2012

Mänuka, Leptospermum scoparium. One of many native plants put to many uses. Captain Cook used it with rimu to make beer.

The botanically-inclined may find something of interest in the just-published Wellington Botanical Society Bulletin. Number 54 includes: the uses of some common native plants. notes on the propagation of native plants. accounts of the diatoms and bryophytes recorded during the 2011 bioblitz on Mana Island. the use of names in botany. detailed accounts of the… Read more »
