“Herbaria are collections of dried preserved specimens that document the identity of plants and fungi. They represent reference collections with many and varied functions including identification, research and education”.
When you take into consideration that the cupboards (here and in other more modern parts of the building, as this was filled to capacity shortly after being created) contain 7.5 million specimens, some 350,000 of which are type specimens, that is the “official” description of how a plants looks like for reference and identification, then you really feel how extraordinary this place is.
Then we were shown some specimens he has dried but not fully identified yet, as they are from his most recent trip to Angola. As expeditions are rather expensive, one has to concentrate on getting a representative selection of the local flora, collecting specimens and avoiding they get damaged (i.e. mould). All the rest can be done once you are back at the Herbarium, where you can consult previous collections to help you identify your specimens (redundant collections are welcome because they document the variety within and/or distribution of species) or any species new to science.

David also showed us an identified specimen from the expedition to Mozambique, and one of the reference specimens they consulted, from the collections, when identifying plants; it’s by 19th century Scottish missionary and explorer David Livingstone (more about his correspondence with Kew).
