Abstract: The tropical rainforest of Amazonia is one of the most species-rich ecosystems on earth, with an estimated 16000 tree species. Due to this high diversity, botanical identification of trees in the Amazon is difficult, even to genus, often requiring the assistance of parataxonomists or taxonomic specialists. Advances in informatics tools offer a promising opportunity to develop user-friendly electronic keys to improve Amazonian tree identification. Here, we introduce an original multi-access electronic key for the identification of 389 tree genera occurring in French Guiana terra-firme forests, based on a set of 79 morphological characters related to vegetative, floral and fruit characters. Its purpose is to help Amazonian tree identification and to support the dissemination of botanical knowledge to non-specialists, including forest workers, students and researchers from other scientific disciplines. The electronic key is accessible with the free access software Xper², and the database is publicly available on figshare: https://figshare.com/articles/GuiaTreeKey/2682550 (doi: 10.6084/m9.figshare.2682550).

Two new combinations in Euploca Nutt. (Heliotropiaceae, Boraginales) and a conspectus of the species of the Guiana Shield area https://phytokeys.pensoft.net/article/6260/ PhytoKeys 61: 101-124

DOI: 10.3897/phytokeys.61.6260

Authors: Christian Feuillet

Abstract: Heliotropium foliatum and Tournefortia humilis are transferred to Euploca Nutt. respectively as Euploca foliata comb. n. and Euploca humilis comb. n. A collection from Guyana has been recently identified as Euploca humistrata, a species previously considered a Brazilian endemic. A collection from French Guiana documents for the first time the species in that country. A key to the species of the Guiana Shield area is given. The species of Euploca from the Guiana Shield are listed with synonymy and a brief description: E. filiformis, E. humilis, E. humistrata, E. lagoensis, E. polyphylla, E. procumbens.

The typification of Cordia flavescens Aubl., the transfer of Firensia Scop. from Cordia L. (Cordiaceae; Boraginales) to the synonymy of Ocotea Aubl. (Lauraceae), and the identity of the species of Firensia https://phytokeys.pensoft.net/article/1545/ PhytoKeys 23: 19-24

DOI: 10.3897/phytokeys.23.4827

Authors: Christian Feuillet

Abstract: Firensia Scop. was based on Cordia flavescens Aubl., a species described and illustrated from a mixed collection that Scopoli never transferred to Firensia. The genus included three additional species formally named by Rafinesque. Currently the four species are placed in three different families and none retained the epithet accepted by Scopoli or given by Rafinesque for reason of priority. A lectotype is designated for Cordia flavescens that places Firensia in the synonymy of Ocotea (Lauraceae).

Tetrameranthus (Annonaceae) revisited including a new species https://phytokeys.pensoft.net/article/1422/ PhytoKeys 12: 1-21

DOI: 10.3897/phytokeys.12.2771

Authors: Lubbert Y.Th. Westra, Paul J.M. Maas

Abstract: The taxonomic revision of the infrequently collected genus Tetrameranthus by Westra (1985) is updated. A new species is described from French Guiana and Amapá, Brazil, increasing the number of species in this genus to seven.

Description and molecular diagnosis of a new species of Brunfelsia (Solanaceae) from the Bolivian and Argentinean Andes https://phytokeys.pensoft.net/article/1408/ PhytoKeys 10: 83-94

DOI: 10.3897/phytokeys.10.2558

Authors: Natalia Filipowicz, Michael Nee, Susanne Renner

Abstract: Brunfelsia plowmaniana N.Filipowicz & M.Nee sp. nov., a species from humid and cloud forests of the Bolivian and Argentinean Andes, is described and provided with a molecular diagnosis, using provisions available in the recently approved International Code of Nomenclature for algae, fungi and plants. Specimens belonging to the new species were previously placed in the polymorphic B. uniflora (Pohl) D.Don, which a molecular phylogeny revealed as polyphyletic. Revision of numerous collections revealed clear morphological differences between the new species and B. uniflora, the type locality of which is in the state of São Paulo, Brazil.
