We report the first records of Bacopa egensis (Poepp.) Pennell from the Brazilian Northeast and the Cerrado domain. This species was collected in the municipality of Chapadinha, in eastern Maranhão state. Photographs, a map of occurrences in Brazil, a description, and comments on the morphology and taxonomy of B. egensis are provided, as well as an...
Here we discuss the importance of vernacular names and encourage authors of new plant species to propose “suggested vernacular names” along with the new species description in cases that there are no vernacular names known. It is not our intention to propose new rules, but we provide recommendations to ensure inclusion of local peoples and dissemin...
The Quadrilátero Ferrífero (Iron Quadrangle [IQ]), in Minas Gerais, Brazil, exhibits high geological and geomorphological diversity, reflected by its high heterogeneity of vegetation. Its rock outcrops, particularly ironstone, harbor endemic-rich plant communities and contribute substantially to the biodiversity of the biomes they are embedded with...
Background and aims – Mitracarpus semirianus , an overlooked new species from the “campo rupestre” of the Chapada Diamantina, in the state of Bahia, northeastern Brazil, is here described and illustrated. Specimens of the new species have been previously identified as M. frigidus or M. lhotzkyanus , with which its distinction is discussed. We also...
Gratioleae are the most species-rich tribe of Plantaginaceae in the tropics, spanning c. 30 genera and > 300 species, with a wide range of morphological variation and ecological strategies. As a first effort towards a phylogenetic classification of Gratioleae we generated a new phylogenetic hypothesis with improved taxa sampling, based on one nucle...
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...

Angelonia Bonpl. in Humboldt & Bonpland (1809: 92) is the largest genus of the neotropical tribe Angelonieae of the Plantaginaceae, formerly included in the Scrophulariaceae, comprising ca. 30 species, and characterized by the strongly zygomorphic corolla with a saccate tube, internally covered with oil-producing trichomes (Souza & Giulietti 2009,...
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...
A new species of Buchnera (Orobanchaceae) from Northeast Brazil is described and illustrated. Buchnera nordestina was first collected by Dr. Francisco Freire Allemão e Cysneiro ca. 160 years ago and remained undescribed until now. We provide notes on morphology, geographic distribution, and conservation status of the new species. Additionally, we p...
Matourea pratensis is a name published by Aublet in 1775 that has never been typified and whose identity has long been obscure. It was historically associated with Stemodia foliosa, as S. pratensis, a species with reported medical importance and wide distribution in the Neotropics. However, its morphology has also been interpreted as more similar t...
Stemodia sensu lato is one of the largest genera of the Gratioleae (Plantaginaceae). Recent phylogenetic studies corroborated the paraphyly of Stemodia in its traditional circumscription and suggested the segregation of S. stellata from this genus. This species belongs to a morphologically cohesive group along with S. cipoensis, S. harleyi and S. l...
Here we describe and illustrate Dizygostemon riparius (Plantaginaceae, Gratioleae) as a new species
from the state of Maranhão, northeastern Brazil. We present morphological and micromorphological descriptions and
comparisons, along with illustrations, photographs, and information on its taxonomy, habitat, geographic distribution
and conservation s...
Philcoxia (Plantaginaceae, Gratioleae) is a genus with seven species of small herbs endemic to Brazil. It is characterized by underground stems and petioles, peltate leaves, and zigzag racemose inflorescences, in addition to a remarkable carnivorous syndrome. The phylogenetic placement of Philcoxia within tribe Gratioleae has been uncertain since i...
In this contribution, we reassess the identity of Stemodia lanceolata (Plantaginaceae) and confirm its occurrence in Brazilian territory. We present a detailed and updated description, a fine illustration, and photographs of this species, along with comments on its distribution, habitat and phenology, and notes on taxonomic affinities. Stemodia lan...
Small forest fragments are recognized as relevant for the preservation of the São Paulo State Semideciduous Seasonal Forest. Our research presents an updated checklist of the vascular flora of the small fragment of legally protected forest, located in the São Paulo State countryside, known as Ibicatu Ecological Station, with the main goal of discus...
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...
A new species of Stemodia (Plantaginaceae) from the Caatinga of northern Minas Gerais, Brazil, is described and illustrated. Stemodia perfoliata was first collected by Auguste de Saint-Hilaire, ca. 200 years ago, and remained unnamed until now. The new species is characterized by the connate-perfoliate leaves, a unique feature in the genus. We prov...
This is a taxonomic study of the species of Plantaginaceae from the cangas of Serra dos Carajás, Pará, Brazil. We recorded five species, all members of the tribe Gratioleae: Bacopa monnierioides, B. myriophylloides, B. reflexa, Scoparia dulcis and Stemodia verticilata. All five species are widespread in Brazil, and B. myriophylloides is here cited...
This is a taxonomic study of the representatives of Orobanchaceae from the cangas of Serra dos Carajás, Pará state, Brazil. We recorded Buchnera carajasensis and B. longifolia in Serra dos Carajás, but only the former occurs in areas of canga and will be treated in this work. Here we present a detailed description, photographs and notes on morpholo...
Carnivory is found in eight additional plant families besides the well-studied and speciose Droseraceae, Lentibulariaceae, Nepenthaceae, and Sarraceniaceae. These include six species-poor or monogeneric families (Drosophyllaceae, Dioncophyllaceae, Cephalotaceae, Roridulaceae, Byblidaceae); the carnivorous genus Philcoxia in the otherwise noncarnivo...
The genus Philcoxia (Plantaginaceae) was published less than 20 yr ago, based on three species, and its circumscription has been broadened more recently with the description of two additional species. Here we report the discovery of two new species from the Brazilian Cerrado, bringing the number of currently known species of Philcoxia to seven. We...
The Serra do Cipó, part of the central portion of the Espinhaço Range in Minas Gerais, Southeast Brazil, is known to have been extensively investigated over the past three decades, especially because of the "Flora da Serra do Cipó" project. Nevertheless, some areas have been poorly collected as the efforts were largely concentrated near the roads....
Buchnera carajasensis is described and illustrated. Information on its conservation status, taxonomy, habitat, geographic distribution, and phenology, along with a key to the Buchnera species found in Pará, is provided. The new species had previously been confused with B. tenuissima, a Mexican species, and is also similar to B. palustris, but exhib...
This is a taxonomic study of the species of Linderniaceae from the cangas of the Serra dos Carajás, state of Pará, Brazil.

Como atividade delineadora dessa proposta, objetiva-se ampliar o conhecimento biogeográfico, florístico, morfológico e sistemático dos grupos de fanerógamas ocorrentes no Maranhão.
Considerando a cobertura do Cerrado e seu grau de ameaça no Maranhão, a presença de diversas bacias hidrográficas no estado e a enorme lacuna de conhecimento sobre a flora aquática e palustre na região, é evidente que um levantamento das espécies de angiospermas associadas a zonas úmidas em áreas de Cerrado do Maranhão é urgente. Assim, o objetivo geral deste projeto é contribuir para o conhecimento da Flora do estado do Maranhão, como subsídio para políticas de conservação e manejo dos recursos naturais, cumprindo os seguintes objetivos específicos: i) Realizar um levantamento das angiospermas aquáticas e palustres de duas grandes unidades de conservação do Cerrado maranhense, o Parque Nacional da Chapada das Mesas (PNCM) e o Parque Estadual do Mirador (PEM); ii) Produzir ferramentas de identificação de plantas aquáticas e palustres do Cerrado maranhense, como guias e chaves interativas ilustradas; iii) Aumentar a representatividade da Flora maranhense nos herbários do estado; iv) Criar uma subcoleção no herbário SLUI com amostras preservadas em meio líquido; v) Criar um banco com amostras de plantas aquáticas e palustres preservadas em sílica-gel para posteriores estudos com DNA-barcoding.
We aim to propose new generic classifications in Gratioleae based on molecular phylogenetic studies in order to redefine the circumscription of Stemodia sensu stricto and correlated genera, taking into account:
i. Monophyly of genera;
ii. Nomenclatural stability;
iii. Minimization of redundancy (avoiding monotypic genera);
iv. Support for monophyly (synapomorphies);
v. Ease in genera recognition;
