With over 8.5 million items, we house the largest and most diverse botanical and mycological collections in the world. They represent approximately 95% of vascular plant genera and 60% of fungal genera. Here is a guide to the different types of collection we hold.
Due to the ongoing COVID-19 situation, our collections will be closed to visitors until 1 June 2021 to ensure safe working conditions for staff and visitors.
For the Herbarium, Fungarium, and Economic Botany collections, loans, samples and image requests, we are gradually working through requests which have accumulated. Requests for seed from the Millennium Seed Bank are being processed, although despatch may take longer than usual.
We apologise for any inconvenience caused.
This contains around seven million preserved vascular plant specimens, these can yield a wealth of information about plants that have been collected around the world over the past 170 years.
Our Fungarium contains specimens from every part of the globe and reflects the importance of fungi as providers of food, medicines, enzymes and essential ecosystem services.
Within the vaults of the Millennium Seed Bank (MSB) is the Seed Collection, which represents the greatest concentration of living seed-plant diversity on Earth. The MSB is a global resource for conservation.

This collection consists of over 76,000 plant specimens preserved in fluid and stored in glass jars. More than 370 families are represented. The mycology spirit collection has 1,250 specimens.
In Vitro Collection
Here we house plant specimens and fungi that have been cultured in artificial growing media. The collection includes 6,000 specimens, including orchids and mycorrhizal and non-mycorrhizal fungi.
We have one of the largest collections of published botanical information in the world, our main subject area is the taxonomy and systematics of wild plants, including collections of herbaria in microform.
Illustrations and Artefacts Collection
An extensive resource of more than 200,000 botanical prints and drawings. There are also works on paper, portraits, photographs, and three-dimensional objects that chart the history of botany.
The Archives Collection
A valuable resource on the history of the discovery, study, transfer and use of the world’s plants and fungi. Here are the official records of RBG Kew and also the personal papers of many botanists.
