Growing knowledge: an overview of Seed Plant diversity in Brazil
An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi…
A new subfamily classification of the leguminosae based on a taxonomically comprehensive phylogeny
The classification of the legume family proposed here addresses the long-known non-monophyly of the traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies and reflects the phylogenetic structure that is consistently resolved.
A molecular phylogeny of the pantropical papilionoid legume Aeschynomene supports reinstating the ecologically and morphologically coherent genus Ctenodon
The most complete DNA sequence data is assembled and Bayesian and maximum likelihood phylogenetic analyses unequivocally confirm the non-monophyly of Aeschynomene.

Conservation uses and impacts of virtual herbaria were more numerous and diverse than the uses captured in the literature review and the survey of Reflora users showed.
Herbarium collection of the Rio de Janeiro Botanical Garden (RB), Brazil
The dataset described in this article contains the data and metadata of plants and algae specimens in the RB collection and the link to access the respective images, as well as a description of the RB dataset as a whole.
The Diversity of Machaerium (Leguminosae: Papilionoideae) in the Atlantic Forest: Three New Species, Nomenclatural Updates, and a Revised Key
The taxonomic revision of Machaerium in the Atlantic Forest included field studies in the northeast, southeast, and south of Brazil as well as the analysis of collections that belong to 40 herbaria, which has allowed the study of about 10,300 specimens.
Taxonomy and nomenclature of the neotropical Machaerium hirtum complex (Leguminosae, Papilionoideae)
Vegetative and reproductive characters were used to delimit the five species, and among the important characters are the dimensions and indumentum of the leaflets, bracteoles, calyx, and banner petal, and the presence of diadelphous stamens.
Brazilian Flora 2020: Leveraging the power of a collaborative scientific network
The shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and…
