New molecular evidence derived from the trnD-T region has unveiled an unexpected relationship for Mimosa pabstiana. Traditionally classified within M. sect. Batocaulon ser. Campicolae, our phylogenetic study reveals its new placement within M. sect. Batocaulon ser. Andinae. This discovery aligns with a biogeographic pattern consistent with the Plei...

Plantas mecanicamente dependentes são aquelas que, em algum estágio de vida, utilizam outros suportes mecânicos para sua sustentação e desenvolvimento (e.g. trepadeiras e epífitas). A fim de contribuir para o conhecimento dessas plantas em ecossistemas flo-restais costeiros do Sudeste brasileiro, procedeu-se ao inventário nos remanescentes veg...

Object-Oriented Programming (OOP) embodies a software development paradigm grounded in representing real-world entities as objects, facilitating a more efficient and structured modeling approach. In this article, we explore the synergy between OOP principles and the TypeScript (TS) programming language to create a JSON-formatted database designed f...

Quararibea floribunda, a species endemic to Brazil, is poorly studied taxonomically, and little is known about its ecology and conservation status. Since its publication in 1842, only a few studies have reported on its morphological circumscription, thus remaining as a complex in the taxonomy of Quararibea. In addition, little is known about its ge...

The nomenclature of the species Luehea macrophylla Pohl is reinstated in this study, drawing on distinctive features such as epicalyx bracts, petals, ovary characteristics, and novel diagnostic fruit characters. The information, including new synonyms and distributional data, complemented by the examination of relevant specimens, is provided. Furth...

The structural diversity of pollinia is one of the most relevant characters for the species classification in Orchidaceae. In this study, we analyzed the development of the pollinia and caudicle in Epidendrum species belonging to the subgenus Amphyglottium, one of the groups with the most variable morphology of the genus. These species have differe...

Argythamnia (Euphorbiaceae) comprises approximately 70 species and is widely distributed in the New World, mainly restricted to seasonal environments. It is represented by seven species in the biogeographic provinces of the Chaco and Pampa, which are characterized by vegetation mosaics of grasslands and forests. Some species are poorly known, with...

We describe Catostemma lanceolatum, a new species endemic to the Brazilian Amazon, which at present is known only in the state of Amazonas. This new taxon is similar to C. altsonii, mainly by the length of its pedicels, but can be distinguished by the shape of its leaflets, the shape and size of the bracteoles, size of its hypanthium, number of cal...

We present taxonomic updates of Anthurium sect. Pachyneurium, A. pluricarinatum, and an amendment to the description of A. leonii. An identification key for the new species and related taxa from Brazilian Atlantic Forest are included, as well as notes about morphological characters, distribution maps and illustrations are provided.

Aguiaria, Catostemma, and Scleronema (Malvaceae) are restricted to Amazonia, and comprise 20 accepted (and one uncertain) species that are typically large trees with significant economic value. No recent studies or taxonomic reviews of these three genera exist, and our preliminary evaluation indicated that many names need to be lectotypified. We pr...
