Guatteria richardii (Annonaceae) rediscovered along with two new species from French Guiana

For the first time, 140 years after the collection of the first specimen and 70 years after the description of Guatteria richardii R.E. Fr. from French Guiana, more specimens that are referable to this species were discovered during a taxonomic treatment for the Flora of the Guianas project, concerning Guatteria Ruiz & Pav. (Annonaceae). In addition, G. intermedia and G. montis-trinitatis, two similar species – the first widely distributed and the second endemic to the Montagne de la Trinité in French Guiana, are described as new to science.
