Herbarium of the Institut de recherche pour le développement (IRD) in French Guiana (CAY)

The “Herbier IRD de Guyane” (CAY) was established in 1965 by R.A.A. Oldeman and harbors nearly 200000 specimens, mostly from French Guiana and nearby countries Suriname, Guyana, Brazil (particularly the state of Amapá), and Venezuela (state of Amazonas). The dataset presented here is the fruit of 30-years’ work by CAY’s staff as well as that of numerous other botanists who have helped make CAY a key scientific platform and leading center of botanical research for the Guiana Shield.
