Here we publish two novelties in Randia, a description of a new species (R. muricata) and the establishment of R. sulbahiana as a new name for Sphinctanthus insignis. Randia muricata is distinguished by a set of features, such as its muricate fruits, and the discolor venation on abaxial surface of the leaf blades, puberulent. The muricate fruits is...
Background and Aims: Bahia is one of the Brazilian states with the greatest diversity of orchids. Species restricted to microhabitats or forming small
populations, being subject to local suppression, have been reported for restingas of the state. The north coast of Bahia has recently been exposed to
intense anthropic pressures, including disordered...
What grows where? Knowledge about where to find particular species in nature must have been key to the survival of humans throughout our evolution. Over time, and as people colonised new land masses and habitats, interactions with the local biota led to a wealth of combined traditional and scientific wisdom about the distributions of species and th...
Climbers germinate on the ground but need external support to sustain their stems, which are maintained attached to supports through modified organs, that is, climbing mechanisms. Specialized climbing mechanisms have been linked to higher diversification rates. Also, different mechanisms may have different support diameter restrictions, which might...
We describe Pterolepis xaxa (Melastomateae, Melastomataceae), a new species collected in “caatinga rupestre” at Licínio de Almeida, Bahia, Brazil. Pterolepis xaxa resembles the recently described Pterolepis haplostemona, both representing the only two species in the genus that are haplostemonous (i.e., with the stamens equal in number to the petals...
Myrtaceae has ca. 6,000 species, distributed into 140 genera with Pantropical distribution. The family is one of the five most representative flowering plants in species richness in Brazilian restinga and is also of great importance for the maintenance of the ecological cycles of this vegetation. However, few studies focus on Myrtaceae in restinga,...
Encounters between flowers and invertebrates are key events for the functioning of tropical forests. Assessing the structure of networks composed of the interactions between those partners leads to a better understanding of ecosystem functioning and the effects of environmental factors on ecological processes. Gathering such data is, however, costl...
We present the first record of Heterosperma (H. ovatifolium, Asteraceae) for Brazil as a result of the taxonomic study of tribe Coreopsideae for Northeastern Brazil. The genus currently comprises 11 species, occurring from southwestern United States to South America and the West Indies. We present a complete morphological description, a photo plate...
Alagoas is a Brazilian state contained in the area of two large and important phytogeographic domains: Atlantic Forest and Caatinga. Although the presence of these domains possibly indicates a considerable biodiversity, floristic studies in the state are still scarce, especially for the family Asteraceae. In this sense, we developed a combined GIS...
Identifying and mapping strategic areas for conservation and restoration actions are essential initiatives to reduce human impact on biodiversity. However, most spatial prioritization does not involve decision-makers and stakeholders, generating a science-application gap. Here, we describe a participatory framework to map strategic areas for conser...
During a taxonomic revision of Eupatorieae (Asteraceae) from Ceará state, Brazil, we found that nomenclatural acts were required according to the International Code of Botanical Nomenclature (ICBN). After analyzing protologues and original material, we have designated three lectotypes for names within Ayapana, Barrosoa, and Dissothrix. Details and...
Understanding the evolution of the tribe Gochnatieae (Compositae) has been the subject of considerable effort in the past decade. This is due to the key position of this tribe in the phylogeny of the sunflower family and the corresponding implications for biogeographic and morphological evolution of Compositae. Previous studies have confirmed the m...

Background and aims- Generic limits of the tropical tribe Gardenieae (Ixoroideae, Rubiaceae) have partly remained unsettled. We produced a new phylogeny of the Randia clade, with emphasis on its Neotropical clade comprising five genera (Casasia, Randia, Rosenbergiodendron, Sphinctanthus, and Tocoyena). The result was subsequently used to evaluate a...
Pectis comprises about 90 species distributed in North America, Mexico, the Caribbean, South and Central America, and the Pacific Islands. In Brazil, the genus is represented by 14 species that mainly occur in the Cerrado and five species that are endemic to the Caatinga domain. During field expeditions to the Lajedo de Soledade archaeological site...
Although Eugenia and Plinia genera belong to different subtribes in Myrteae (Myrtaceae), shared morphological features have led to frequent mistaken identity to these species. Molecular phylogeny and morphological studies in Plinia show that Plinia martinellii and Plinia sebastianopolitana should be combined within the generic concept of Eugenia. I...
The four following Diptera families are peculiar because they are predominantly phytophagous: Cecidomyiidae, Agromyzidae, Lonchaeidae and Tephritidae; which is uncommon for dipterans. Tephritine’s larvae, depending on the species, consumes leaves, stems, flowers or roots of their host plants. Some tephritines feeds on flower heads of weed Asteracea...
