English botanist George Bentham (1800–84) is most famous as the author of the popular Handbook of the British Flora (1858), which ran into many editions. A distinguished scientist, Bentham was elected a Fellow of the Royal Society in 1862, and served as President of the Linnean Society of London for thirteen years (1861–74). Originally published in 1826, this catalogue of plants from the Pyrénées region of France is Bentham's second work. Inspired by French botanist de Candolle (1778–1841) as well as by the analytical methods of his uncle, the famous philosopher Jeremy Bentham, this book is a systematic overview of the plants found between Figueras, in the north of Spain, and Bordeaux, Narbonne and Montpellier in France. The book opens with the story of Bentham's 1825 three-month trip through the Pyrenees region, with botanist G. A. Walker Arnott (1799–1868), on which the Catalogue is based.
