The Botanical Society of Britain and Ireland (BSBI) is a scientific society for the study of flora, plant distribution and taxonomy relating to Great Britain, Ireland, the Channel Islands and the Isle of Man. The society was founded as the Botanical Society of London in 1836, and became the Botanical Society of the British Isles, eventually changing to its current name in 2013. It includes both professional and amateur members and is the largest organisation devoted to botany in Britain and Ireland. Its history is recounted in David Allen's book The Botanists.2

Products and brands

The BSBI's attitudes to publication of details of locations of rare plants have changed over time. In 1991, it publicly criticised the author John Fisher, for writing "A Colour Guide to Rare Wild Flowers", a book which gave details of the locations of a selection of rare plants, stating that it was not in the interests of conservation. Following this criticism, Fisher resigned his membership of the BSBI. Fourteen years later, David Pearman, the Society's General Secretary, contrasted the way in which Fisher was, as Pearman termed it, "hounded out", with the more open attitudes that had then taken hold. In more recent times, the BSBI has produced or supported the production of a number of County Rare Plant Registers, books which list all known locations for all rare plants in their county of coverage.
