The botany curation team have recently completed cataloguing some of the more unusual items in their care, the bound volumes and exsiccatae. A dataset listing those collections has been published on the Museum’s data portal. In this blog, Jo Wilbraham, Norbert Holstein and Mark Carine, discuss some of the treasures to be found among the Museum’s extensive collection of botanical bound volumes and exsiccatae.
Legumes are a group of plants that include soybeans, peas, chickpeas, peanuts and lentils. They are a significant source of protein, fiber, carbohydrates, and minerals in our diet and some, like the cow pea, are drought resistant.
A new paper has been published in Biodiversity Journal about a project that the digitisation team started in 2018 with the Royal Botanic Gardens Kew (project Lead) and the Royal Botanic Garden Edinburgh, to collectively digitise non-type herbarium material from the legume family This includes rosewood trees (Dalbergia), padauk trees (Pterocarpus) and the Phaseolinae subtribe that contains many of the beans cultivated for human and animal food.
This project was made possible through Department for Environment Food & Rural Affairs (DEFRA)-allocated Official Development Assistance (ODA) funding, distributed by the UK government in its “global efforts to defeat poverty, tackle instability and create prosperity in developing countries”.

The legume groups Dalbergia, Pterocarpus and Phaseolinae were chosen for digitisation to support the development of dry beans as a sustainable and resilient crop, and to aid conservation and sustainable use of rosewood and padauk trees. Some of these beans, especially cow pea and pigeon pea, are sustainable and resilient crops, as they can be grown in poor-quality soils and are drought stress resistant (Varshney et al. 2009). This makes them particularly suitable for agricultural production where the growing of other crops would be difficult.
Digitally discoverable herbarium specimens can provide important information about the distribution of individual species, as well as highlighting which species occur naturally together. While there have been collaborative efforts between herbaria in the past, these have tended to prioritise digitisation of type specimens – as the example specimens for which a species is named, types are important to identification, but as individual specimens don’t offer insights into species distribution over time. By focusing on the non-types across the world and over the last 200 years, we have released a brand-new resource to the global scientific community.
Searching for beans
This collection was digitised by creating an inventory record for each specimen, attaching images of each herbarium sheet, and then transcribing more data and georeferencing the specimens, providing an accurate locality in space and time for their collection.
We originally had four months and three members of staff to digitise over 11,000 specimens. The Covid-19 lockdown was ironically rather lucky for this project as it enabled us to have more time to transcribe and georeference all of the records.

We were able to assign country-level data to 10,857 out of the total number of 11,222 records. We were also able to transcribe the collectors’ names from the majority of our specimen labels (10,879 out of 11,222). Only 770 out of the 2,226 individuals identified during this project collected their specimens in ODA listed countries. The highest contributors were: Richard Beddome (130 specimens), Charles Clarke (110), Hans Schlieben (98) and Nathaniel Wallich (79). The breakdown of records by ODA country can be seen in the chart below.

From our data, we can see the peak decade of collection was the 1930s, with almost half (4,583 specimens or 49,43%) collected between 1900 and 1950 (Fig. 10). This peak can be attributed to three of our most prolific collectors: Arthur Kerr, John Gossweiler and Georges Le Testu, all of whom were most active in the 1930s. The oldest specimen (BM013713473) was collected by Mark Catesby (1683-1749) in the Bahamas in 1726.

An interesting, but perhaps unsurprising, finding is that our collection is strongly male dominated. There are only two women (Caroline Whitefoord and Ynes Mexia) in the list of our top 50 plant collectors and they are not close to the most prolific collectors. We identified more women in the rest of our records, but their contribution is on average less than 25 specimens per person in the dataset consisting of more than 10,000 specimens. In contrast, the top five male collectors contributed 10% of our collection.

Releasing Rosewoods
Both the Pterocarpus and Dalbergia genera include species that are used as expensive good quality timber that is prone to illegal logging. Many species such as Pterocarpus tinctorius are also listed on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. By releasing this new resource of information on all these plants from three of the biggest herbaria in the world is that we can share this date with the people who are taking care of biodiversity in these countries. The data can be used to could be used to identify hotspots, where the tree is naturally growing and protect these areas. These data would also allow much closer attention to be paid to areas that could be targets for illegal logging activity.
Pterocarpus tinctorius is a species of padauk tree that is listed as endangered on the IUCN Red List. Cowpea (Vigna unguiculata) is a food and animal feed crop grown in the semi-arid tropics.

The ODA-listed countries are economically impoverished and disproportionally prone to be disadvantaged with the changing climate whether from flood or drought or increase in temperature. Using data to identify good, nutritious plant species that can be grown in such conditions can therefore benefit local communities, potentially reducing dependence on imports, aid and on less resilient crops.
The Codex Vindobonenis is a Byzantine compendium of pharmaceutical knowledge produced in around 512 C.E.. In this blog, Hanouf Al-Alawi and botany curator John Hunnex discuss their recent project examining the overlooked Arabic and Persian annotations on the plant descriptions included in the work.
This International Women’s Day, I want to celebrate the incredible achievements of Grace Mary Crowfoot, a botanist, textile archaeologist, anthropologist, and pioneering anti-FGM advocate and to share her story of breaking biases and fighting inequality for women.
The UK holds hundreds of millions of natural history specimens of scientific importance. Exactly how many specimens and what those specimens are, is currently unknown. Unveiling the contents of the UK’s collections will open the door to further digitisation and unlock the full scientific potential of UK natural science collections.
Digitising, the process of converting physical information into a digital form, the UK’s natural science collection, opens up a unique and valuable national resource to the world and enable the UK to be part of current and future scientific collaborations to find solutions to the biggest challenges of our time.
The private herbarium of the eminent eighteenth-century naturalist and explorer Sir Joseph Banks became one of the founding collections of the Natural History Museum’s herbarium following his death 200 years ago this year, in 1820.
The legacy of Banks’s voyages overseas – and particularly the Endeavour voyage with James Cook – has been well documented. This post, by Fred Rumsey, looks at the British specimens Banks collected, or was gifted, and considers the significance of those collections today.
In a recent blog post we looked at the contribution of the eminent eighteenth-century naturalist and explorer Sir Joseph Banks to the herbarium at the Natural History Museum. Banks died in 1820 – 200 years ago this year – at the age of 77. His private herbarium subsequently became one of the founding collections of the Natural History Museum’s General Herbarium of over 5 million specimens.
As a young man, Joseph Banks was a traveller. For seven years, from the age of 23, his travels took him across the globe, to all continents except Antarctica, and they established his reputation as a leading natural historian of the day. Collecting specimens was at the very core of what he was doing during those voyages undertaken during the late 1760s and early 1770s. Botanical specimens that he collected are today in the herbarium at the Natural History Museum .
In this post, we look at Banks’s botanizing during the voyages he made overseas – to Newfoundland and Labrador in 1766, on James Cook’s first Circumnavigation from 1768–71 and to Iceland in 1772 – and we consider the scientific significance today of the collections that he made.
Sir Joseph Banks was an eminent eighteenth-century naturalist and explorer. His travels and scientific patronage enabled him to amass specimens from around the globe.
An avid botanist, his private herbarium was one of the founding collections of the Museum’s herbarium.
