Survey of Flowering Plants Stored in Fluid Preservatives Across European Herbaria

Written by Ranee Prakash, Senior Curator (Flowering Plants), Algae, Fungi and Plants Division, Department of Life Sciences, Natural History Museum, London.

A survey of flowering plant material stored in various fluid preservatives across several European herbaria/institutions was carried out a few years ago. The feedback received from the survey is shared and shows that the majority of the herbaria use 70% IMS (industrial methylated spirit) to store their collections.

Introduction

The seed plant collections (stored in various liquids such as formalin, some have unknown liquids, and some mention poison) form a relatively small yet significant part of the botanical holdings at NHM (Natural History Museum). They include some important material dating back to the mid 1800’s and type collections such as the world’s largest flower Rafflesia arnoldii collected by Robert Brown. However, these wet collections have remained a somewhat underused asset and are in dire need of curatorial attention.

In continuation to this aim, a survey of flowering plants stored in spirit collections across various institutions in Europe was carried out in 2012 so as to assess what preservatives other institutions were using and what would be the best method to store the collections at NHM for posterity. The objective of this survey was to gather information on:

  • How big the spirit collection is
  • How the collection is used
  • Which liquid preservatives the flowering plant collections are stored in

The Missing Lynx: The Past and Future of Britain’s Lost Mammals

Written by Jack Ashby, Manager of the University Museum of Zoology, Cambridge, and author of Animal Kingdom: A Natural History in 100 Objects.

A good title goes a long way, and based on that alone I was excited to receive a review copy of Ross Barnett’s new book through the post. I knew of Ross from Twitter – and I can heartily recommend following him for a whole host of natural history-related wonders, particularly around climate change, ancient mammal DNA and palaeontology. As a result, I was slightly surprised that he had written a book that I assumed – from the clever title – was about reintroducing the lynx to Britain.

That is, in fact, not what the book is about. Instead, it takes us species-by-species, chapter-by-chapter, through the incredible range of beasts that have disappeared from the British Isles in recent millennia (I should have paid more attention to the subtitle). We learn about the woolly mammoths and rhinos, the huge cave bears and their slightly smaller relatives, cave lions and cave hyenas, sabretooth cats, massive species of cattle and deer, as well as wolves, beavers and, yes, lynx. All of these stories are told in the voice of a person clearly fascinated and excited by the things he has been studying all his life, and with a dry sense of humour.

Invertebrates In Vitro

Written by Paolo Viscardi, Curator of Zoology, National Museum of Ireland – Natural History

I’m not sure why, but people really seem to love Blaschka models.

They are the subject of a surprisingly large number of enquiries at the National Museum of Ireland — Natural History (AKA the Dead Zoo), where I look after the zoology collections.

If you’ve not heard of the Blaschkas, they were a father and son company of lampworkers based in Dresden, who supplied museums and universities around the world with glass models for teaching and display. Between 1864 and 1890 they made mail-order models of invertebrates (alongside glass eyes and medical equipment), then from 1890 until 1936 they worked exclusively for Harvard University on the Ware collection of glass flowers.

At the Dead Zoo we have a particularly large and comprehensive collection of the invertebrates, with around 590 models acquired in lots between 1874 and 1888. I say ‘around’, because many of the models are made up of multiple parts, with different developmental stages, enlargements and details that are classed as elements of the same model.

Brendel Plant Model Survey

Written by Donna Young, Curator of Herbarium, World Museum, National Museums Liverpool

Inspired by the project led by the Corning Museum of Glass, which looked at holdings of Blaschka models, I am embarking on a project to map and document collections of Brendel botanical models worldwide.

The objective of this project is not only to provide a useful resource to be used in the curation of anatomical models, but to document their past and present use – promoting and bringing awareness of these collections to new audiences.

Anatomical Models

The nineteenth century was the golden age of scientific discovery, and as the century progressed, the teaching of science in schools, academies and museums evolved to reach a new mass public audience. Science was no longer the exclusive preserve of an elite few.

Changing teaching techniques promoted this transformation and pedagogical inquiry was seen as a constructive and involved way of learning. The written and spoken word was supported by the use of visually instructive wall charts and classroom demonstrations. The introduction of interactive teaching models encouraged audiences to understand nature using new and original perspectives.

Botanical models were used to illustrate and demonstrate plant anatomy. Unlike living material, their use was not restricted by seasonal availability and they were ideal for demonstrating small or ephemeral details which are difficult to preserve.

In 1827 Louis Auzoux established his workshop in France, manufacturing human and veterinary anatomical models from papier-mâché. The company also produced botanical models, which were widely distributed to universities and schools in France, particularly to support the expansion in teaching agricultural science.

Beauty in the Eye of the Turtle Holder

Written by Becky Desjardins, Senior Preparator, Naturalis Biodiversity Center

Recently, we were cleaning up some mounted turtles and turtle shells destined to go in the new Live Science Hall. All of these came from Amsterdam Schipol airport, where they had been confiscated by customs agents.

When taking a closer look at these animals we noticed that none of these specimens had the normal glass eyes used in taxidermy. Instead they were made of other materials less commonly used for mounting animals.

Quite a few of the turtles had eyes made from shells. Some appear to be cowrie, but we could not identify them all, and a few other shells were painted black making them impossible to identify.

Then we came across one turtle with a glass eyes made from a marble. Funnily enough, they used a “cat’s eye” marble and the coloured core actually made the eye look quite lifelike.

NatSCA Digital Digest – February

Compiled by Sam Barnett, NatSCA Volunteer and PubSci Committee Member.

What should I read?

If you’ve not been keeping up with your South American sauropod discoveries, this next item might have completely passed you by. A new dinosaur has been named Bajadasaurus pronuspinax and hails from the Bajada formation of Patagonia. It bears a similarity to Dave Hone’s favourite dinosaur Amargasaurus but with far more flamboyant adornments – as illustrated here by Natee Himmapaan. You can read all about Bajadasaurus over at Nature or you can find a very good piece on it by Ed Yong here.

In China, Qiang Fu and colleagues have proposed an earlier date for flowering plants; much, much earlier. This has been met with some cynicism from the palaeobotanical community and we’re looking forward to seeing how that plays out. Continue reading
