Plymouth Marine Biological Association MBA

The MBA seaweed herbarium was initially assembled by Dr Mary Parke in the 1940s from various collections at the MBA and from her own material. This has been added to steadily up to the mid-1980s by various phycologists either working at, or visiting, the MBA. The earliest material in the collection is from the 1830s from a number of collectors but most of the material collected since 1950 has been added by Dr Parke or Dr Gerald Boalch.
