New circumscription, morphology and synopsis of Chamaecrista sect. Chamaecrista ser. Coriaceae (Leguminosae)
A new circumscription of Chamaecrista sect. Chamaecrista ser. Coriaceae is presented based on the results of molecular and morphological analyses. The series is monophyletic upon exclusion of three species that were included within it by Irwin and Barneby. Morphological variation within the series is discussed. Characters previously neglected, such as...Rando, Juliana Gastaldello ; Pirani, José Rubens ; Cota, Matheus Martins Teixeira ; Lewis, Gwilym Peter

A novel phylogenetic infrageneric classification of Baccharis (Asteraceae: Astereae), a highly diversified American genus
We present the hitherto most comprehensive phylogenetic hypothesis for Baccharis. Our results confirm that subtribe Baccharidinae is a monogeneric group and support a broad circumscription of Baccharis as monophyletic with the inclusion of all genera that have been previously segregated from it (Baccharidastrum, Baccharidiopsis, Heterothalamulopsis, Heterothalamus, Lanugothamnus). We provide comprehensive...Heiden, Gustavo ; Antonelli, Alexandre ; Pirani, José Rubens

Domestication of the Amazonian fruit tree cupuaçu may have stretched over the past 8000 years.
Amazonia, one of the largest and most biodiverse ecosystems on Earth, is a significant yet less-known arena for ancient plant domestication. Here, we traced the origins of ( ), an Amazonian tree crop closely related to cacao ( ), cherished for its flavorful seed-pulp, by employing an extensive genomic analysis... -

Human influence on the distribution of cacao: insights from remote sensing and biogeography.
Cacao ( , Malvaceae) is an important tree crop in Africa and in the Americas. Current genomic evidence suggests that its original range in Tropical Americas was smaller than its current distribution and that human-mediated dispersal occurred before European colonization. This includes regions like Mesoamerica and Eastern Amazonia where cacao...
