Herbarium specimen of Alaria esculenta.
By far the largest section of the algal collections consists of dried, pressed specimens on herbarium sheets.
The specimens are often labelled with essential data, such as date and place found and special habitat conditions.
Examples of encrusted rocks.
The box collection consists mostly of bulky calcareous algae and coralline crusts on rocks and stones.
The collection includes the important collections of Linda Irvine and Yvonne Chamberlain, co-authors of the Seaweed flora of the British Isles volume covering the coralline algae.
Microscope slides of algae in the Schmitz collection.
There are microscope slide collections of both marine and freshwater algae.
Two collections of particular historic importance, the Schmitz and Batters collections, are housed separately, each in their own purpose-built slide cabinets.
The Schmitz collection, containing around 7,000 slides, is important because the slides hold fragments used for the Rhodophyta part of Engler and Prantl’s ‘Die natürlichen Pflanzenfamilien’ (1896 and 1897). Many are also nomenclatural type specimens from other major world collections.
Algae specimens in spirit liquid.
The liquid-preserved collections consist of jars and tubes of freshwater and marine specimens. The preservative is mostly four per cent formaldehyde.
We do not actively add to this collection, although it does include some contemporary material as well as important historic collections.
Unincorporated collections stored in a annotated folder system.
‘Unincorporated material’ refers to specimens that have not been processed sufficiently to add them into the main herbarium collections, for example material that may be unidentified.
Some batches of duplicate specimens are also stored here.
Some of this material will be processed and added into the main collections over time. Some will remain in this batch storage system, where it is still accessible for research.
The material is stored in folders in herbarium cabinets, with associated data giving a broad description of the folder contents.
Threde's Algen der Norsoe, 1832.
Approximately 80 bound volumes of algae are held in the herbarium.
These include several scientifically significant volumes containing nomenclatural type specimens as well as culturally important examples of Victorian seaweed albums.
William Harvey's plates of Australian algae.
A small number of supporting collections are also housed within the algal herbarium.
