Field work is a key part of scientific research at Te Papa. Each year, Research Scientist Heidi Meudt spends about three weeks in the field collecting specimens for her taxonomic research on native New Zealand forget-me-nots (Myosotis).
In January 2017, she travelled to three main areas in northern South Island (Cobb Valley, Mt Owen and ranges around St Arnaud) together with Collection Manager Ant Kusabs to hunt for some more forget-me-nots.
Read on to learn about the different species of forget-me-nots they found on the trip, as well as other specimens which are now part of Te Papa’s Botany collection.
Cobb Valley, Kahurangi National Park
For the first part of the trip, we teamed up with colleagues Shannel Courtney, Simon Walls, and Rowan Hindmarsh-Walls (Department of Conservation), whose extensive local knowledge of the flora and geography of the park was indispensable.

With their help, as well as using detailed information from collections and databases at Te Papa and other New Zealand institutions, we found and collected several different species, including the following:
- Myosotis chaffeyorum and M. mooreana, two rare species endemic to this area, described in 2012 by Te Papa Botany Curator Carlos Lehnebach.


- Myosotis brockiei, also endemic to Nelson.

- Myosotis macrantha, common throughout South Island mountains, with its uniquely-coloured flowers and one of the six forget-me-not species that is Not Threatened.

Owen Massif, Kahurangi National Park
Mt Owen has a fascinating geological history, which might help explain why its flora and fauna are unique, including some special forget-me-nots. Although the weather was not always cooperative, Ant and I nevertheless made some exciting collections.


- Finding a population of Myosotis angustata was one of the highlights of the day!

- And although it is impossible to choose a favourite species, the yellow-flowered Myosotis concinna – known only from this area – would probably be near the top of the list.


- We also found Myosotis australis, another common (and Not Threatened) species throughout the South Island. But unlike most New Zealand forget-me-nots, M. australis is also native to Australia and Papua New Guinea. Current morphological and genetic research is underway to determine if M. australis is indeed one wide-ranging species, or rather comprises multiple species that will require scientific description.


Ranges near St Arnaud
On the third and final part of our field trip, we teamed up with Jessie Prebble (former Te Papa PhD student, now Plant Systematist at Landcare Research!) and keen student Zuri Burns, who were also doing field work in the same areas.

We found populations of two additional forget-me-not species of note:
- Myosotis laeta is only found in the northern Southern Island.

- Myosotis traversii, on the other hand, is a common species found on high-elevation scree slopes throughout the South Island. We also found it in the Cobb Valley, where we somehow managed to collect despite very strong winds.


In total, we found and collected several populations of nine of the 40+ native Myosotis species in New Zealand, which we are actively researching now. Which is your favourite? We also made several other important collections for the museum. Stay tuned to future blogs about our results, and, of course, our next field trips.

Thanks, Heidi. That was very interesting. I suddenly remembered Chatham Is Forget Me Nots only to discover they’re not quite a myosotis species. So I’ve had an intriguing trip.
Hi again Olwen. I might need to write a blog about the Chatham Island forget-me-not (Myosotidium) because that’s the forget-me-not that everyone seems to know in New Zealand. You are right that although it is in the same family (Boraginaceae) it is not closely related. Glad you have been doing some botanical learning. Thanks for your interest. Heidi
Lovely to see Ant Kusabs in his natural element. Please pass on my regards.

Thanks Ian, will do! I am very fortunate to have such a great co-worker. Cheers, Heidi
Although they’re all cute, the concinna’s yellow flowers and the chunky angustata really stand out. Great photography! Any reason why we don’t seem to have blue ones here or pink ones?
Thanks very much for your positive comments. Your question about flower colour is a great one! It may have to do with the pollinators of the flowers. Flower colour is one of the many ‘cues’ that pollinators use to find flowers, which they use as a food source to harvest pollen and/or nectar. Some flowers have certain colours, odor, shape etc. to attract specialised pollinators, but in New Zealand, many of our flowers are small, white or pale with and open dish-shape to attract unspecialised or generalist flies and bees. A nice but technical review paper about the subject can be found here: http://www.tandfonline.com/doi/abs/10.1080/0028825X.2005.9512943. In fact one of the co-authors on that paper, Alastiar Robertson, also did his PhD research on the pollination biology of a few of our native Myosotis species, some of which have the ‘unspecialised’ white flowers, but others (like M. macrantha and M. concinna shown here) have more ‘specialised’ flowers, which might indicate a more specialised pollinator (e.g. a certain species of insect). This is certainly an area very ripe for additional study! Finally we do have some blue ones in the subantarctic islands of NZ, check it out: M. capitata: http://www.nzpcn.org.nz/flora_details.aspx?ID=591 and M. antarctica: http://nzpcn.org.nz/flora_details.aspx?ID=589 Cheers, Heidi
