Using legacy botanical literature as a source of phytogeographical data
Methods – Three contrasting data mobilisation projects are used as case studies for the extraction of phytogeographic data. Two were digitisations and XML mark-up of floras, the Flore d'Afrique Centrale from the 20th century and the Flora of Northumberland and Durham from the 19th century. A third case study used Chenopodium vulvaria L. as a test case, where I attempted to recover as much phytogeographic data as possible for one species, both from literature and from herbarium specimens.
Results – A large amount of useful information was extractable from legacy literature. The main limitations are that most localities need georeferencing and that observations are only rarely associated with a precise date. In the case of C. vulvaria literature contributed about 20% of all available observations of the species. Literature becomes a progressively more important source of data the further back in time one looks. However, useful observations become much rarer earlier than about 1850.
Main conclusions – Sourcing phytogeographic data from legacy literature is valuable. It contains observations and links to other data that are unavailable from any other source. Nevertheless, its extraction takes a substantial investment in time. Before commencing on such a project it is important to prioritise work and understand the limitations of such data, particularly with regard to georeferencing.

Plant Ecology and Evolution (a continuation of Belgian Journal of Botany, incorporating Systematics and Geography of Plants) is an international journal devoted to ecology, phylogenetics and systematics of all ‘plant' groups in the traditional sense (including algae, cyanobacteria, fungi, myxomycetes), also covering related fields such as comparative and developmental morphology, conservation biology, evolution, phytogeography, pollen and spores, population biology, and vegetation studies. It is published by Meise Botanic Garden and the Royal Botanical Society of Belgium and contains original research papers, review articles, checklists, short communications and book reviews.
