This paper encompasses the taxonomic study of Chloris and Stapfochloa in Paraíba State, contributing to the knowledge of local agrostological flora. Consultations on the virtual databases, as well as visits to physical herbaria, collecting expeditions and fieldwork observations, were made. In the study area, the occurrence of five species of Chlori...

The shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiver-sity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxo-nomic impediment to biodiversity research and conservation planning. The taxonomic impedi...

Bouchea agrestis Schauer (Verbenaceae) is an endemic species known from Bahia, Ceará, Maranhão, and Piauí states, all of them in the Northeastern Brazil. This work expands its distribution to Paraíba state, 540 km distant from the nearest recorded locality, in Juazeiro municipality, Bahia. This work indicates the need of more floristic surveys alon...

The urge to organise the world around us is an essential part of human nature. Naming and categorising enable us to store and access information ef ciently. The need to name and categorise extends to the natural world and, in particular, to living organisms. The science underpinning this area of knowledge is called Taxonomy, and is as old as humani...

This paper presents the floristic survey of the vascular plants from a restinga patch in Nísia Floresta, an area belonging to the Bonfim-Guaraíras Environmental Protection Area (APA), in Rio Grande do Norte state, Brazil. The area is a transitional formation among salt marshes, sand dunes vegetation and Atlantic forest, besides having dozens of int...

Justicia sphaerosperma Vahl (Acanthaceae) is a perennial erect subshrub described for the Caribbean. In this paper, we present its first records for Ceará, Maranhão, Pará, Paraíba, and Rio Grande do Norte states in Brazil. Considering that this species is poorly known in Brazil and that most herbarium specimens were indeterminate, here we provide i...

Local, polemic, floristic, personal, independent, artistic, lacking any respect for traditional styles of scientific journals, or their metrics, questioning why reviewers and editors are not paid by publishers that charge for subscriptions of their journals, in this paper we propose a local journal called PlantNow, that will act locally, enhancing...

Combining development and conservation of the environment is one of the greatest challenges of our time. With increasing urbanization and the consequent fragmentation of natural habitats, green spaces in urban areas become an important tool for biodiversity conservation. However, to conserve biodiversity in urban areas it is suggested to use native...

Sida santaremensis Mont. (Malvaceae) is a species previously reported only from Amazon Rainforest, Central Brazilian Savanna and Atlantic Forest phytogeographical domains. In this paper, we present the first record of S. santaremensis for Paraíba state in Caatinga domain. This is the second species of Sida sect. Sidae recorded for Paraíba, together...

The Global Strategy for Plant Conservation (GSPC) was established by the Conference of Parties in 2002 to decrease the loss of plant diversity, reduce poverty and contribute to sustainable development. To achieve this overarching goal, the GSPC has established a series of targets, one of which is to ensure that plant diversity is well understood, s...

Here we present the Combretaceae flora for Rio Grande do Norte state, Northeastern region of Brazil, based on morphological analyses of specimens deposited in the herbaria ASE, EAC, FUEL, HEPH, HST, HUEFS, IPA, JPB, MAC, MBM, MOSS, NY, UEC, and UFRN, bibliography and images of type specimens. Twelve species belonging to five genera are recorded: Bu...

New occurrences of 10 species of angiosperms from Rio Grande do Norte state are reported. These data were collected by an environmental consultancy prior to the establishment of a wind farm. These records demonstrate the presence of knowledge gaps in the Caatinga flora of the state and show how an environmental consultancy can positively contribute...

A National Forest Inventory (NFI) encompassing the entire territory of Brazil is in progress. It is coordinated and promoted by the Brazilian Forest Service of the Ministry of Environment.
