Barbara Hogarth was for almost 20 years the Botanical Society of the British Isles (BSBI) recorder for the vice-county of Angus. This role, the many years spent gathering records, and her work surveying and mapping vegetation has afforded her greater awareness of plants that tend to be overlooked and it was this awareness that prompted her study of Alchemilla Lady's-mantle micro-species. The publication of her book Alchemilla: A Study of the Alchemilla Micro-Species found in Northern Scotland, which describes each of the Alchemilla micro-species found in Scotland in detail was followed by this practical field guide which offers a straightforward, no-nonsense approach to the identification of Alchemilla plants in the British Isles.
