Species occurence dataset of the pantropical Caesalpinia Group

A total of 17,260 species occurrence data spanning more than 200 species and infraspecific taxa and all 26 genera, were assembled to generate the Caesalpinia Group distribution maps. Vouchered occurrence records (Basis of Record: Preserved Specimen) were downloaded from the Global Biodiversity Information Facility (GBIF; (June 2017), SEINet (http://swbiodiversity.org/seinet/) and DryFlor (http://www.dryflor.info/). To improve accuracy, the distribution of each species was mapped and checked against monographs or expert knowledge, and obvious outliers removed. Occurrence points located in the sea, in botanical gardens, on the centroid of a country, or with coordinates only at the level of degrees, were removed. Data handling was performed in R (R Core Team, 2018). This dataset was generated as part of the following publication: Gagnon, E., Ringelberg, J., Lewis, G.P., Bruneau, A. & Hughes, C.E. (2018; accepted, pending revisions) Global Succulent Biome phylogenetic conservatism across the pantropical Caesalpinia Group (Leguminosae). New Phytologist.
