Inspired by the work of Alexander von Humboldt, Hewett Cottrell Watson (1804-1881) became Victorian Britain's leading phytogeographer (the study of plant distribution), and his research contributed to Charles Darwin's Origin of Species.

'Watson's major botanical endeavour was producing several versions of a work first entitled Outlines of the Geographical Distribution of British Plants (1832); it reached its most extensive form as Cybele Britannica, or, British Plants, and their Geographical Relations (4 vols., 1847–59). Volume four contains his most detailed phytogeographical conclusions. After publishing several supplements, he summarized his data in Topographical Botany: Being Local and Personal Records towards Shewing the Distribution of British Plants (2 vols., 1873–4). He was working on a second edition of it when he died; it was completed by John G. Baker and William W. Newbould (1883) (Oxford Dictionary of National Biography). Watson was also responsible for the foundation of botanical exchange clubs and the publication of the London Catalogue of British Plants, which amassed the contributions of thousands of amateur and professional botanists across Britain.'
