A new species of fern for New Zealand, Asplenium lepidotum

The abundance of scales on the upper surface of young fronds is a distinguishing feature for Asplenium lepidotum.  These scales appear as black dots.  Photo by Leon Perrie.  © Te Papa.

Finding and naming new species is a core part of the job for Te Papa’s scientists.  More than 2500 animal and plant species have been named by museum staff since 1865.  A recent example is the fern Asplenium lepidotum, described by myself and Pat Brownsey.  This brings the number of indigenous ferns and lycophytes in… Read more »

Botany travels: representing New Zealand around the world

My name is Heidi Meudt and I’m a Research Scientist in Botany at Te Papa, currently doing taxonomic research on New Zealand’s native forget-me-nots. As part of my job, I occasionally attend scientific conferences in New Zealand and overseas. I’ve blogged before about some of the reasons that international conferences are important for those of us doing… Read more »

Fascinating forget-me-not pollen


Now that springtime is upon us in New Zealand, many plants are starting to flower, producing pollen. Many of us have a negative association with pollen due to its role in causing allergies [PDF, 172KB]. But not all pollen causes allergies, and pollen is of course extremely important to the biology and ecology of flowering plants. Some… Read more »

Unforgettable names for a new forget-me-not species

We asked you to suggest a species name for a newly discovered New Zealand forget-me not. In addition to some creative descriptive and geographic names, many of your suggestions were commemorative. The practice of naming species after famous people (real or fictional) dates back over 250 years. Are such names just a gimmick, or an effective means of promoting… Read more »

During the recent expedition to central Guadalcanal in the Solomon Islands, my job was to document the ferns and lycophytes. This was at the invitation of Marika Tuiwawa (University of South Pacific) who led the expedition’s plant team. It built on my previous experience working with ferns in Fiji, New Caledonia, Australia, and New Zealand. (As… Read more »

A focus for my research in 2014 has been preparing an account on the Gleicheniaceae fern family for the online Flora of New Zealand. More on the revolutionary online Flora of New Zealand. The Gleicheniaceae in New Zealand comprises nine species in the genera Dicranopteris (one species, restricted to central North Island thermal areas), Gleichenia… Read more »

New Zealand has a new tree fern – kind of. Te Papa Research Fellow Patrick Brownsey and I have recently recognised a subspecies within the stumpy tree fern, tuokura, Dicksonia lanata.  The new name is Dicksonia lanata subspecies hispida.  It is only kind of a new tree fern, as it was first recognised as something different… Read more »
