The botany collection holds an estimated 5.25 million specimens of algae, bryophytes, ferns, seed plants, lichens and slime moulds from all over the world.

The collection spans a period from the seventeenth century to the present and includes a number of historically important collections such as those of:

  • Sir Hans Sloane
  • Sir Joseph Banks

The collections are being digitised and are accessible via the Data Portal.

The algae collection is one of the largest in the world, with more than a quarter of a million specimens from around the globe.

Examination of this material has revealed new taxonomic and distributional data, with more yet to be discovered.

One of the world’s largest diatom collections accumulated from the early nineteenth century to the present day.

One of the most important collections of ferns and other seed-free vascular plants in the world, with around 280,000 specimens.

The two million General Herbarium specimens represent a unique global resource for studying global seed plant diversity.

The lichen collection is one of the largest in the world, consisting of at least 10,000 type specimens, and is an important resource for research.

The collection has a global scope and was the foundation for the book Monograph of the Myzetozoa by A and G Lister.
