The botany collections at the World Museum contain around 400,000 botanical specimens and associated items. Many of the specimens are of national and international significance. The department also houses an extensive botanical library.
The collections are particularly rich in material from some of the pioneer explorations of the world's flora. Liverpool's worldwide links as a port are highlighted in the collections which hold a wide geographic spread. The collections date back to the late 1700s and are still being added to today.
