Senna sect. Chamaefistula (DC. ex Collad.) H. S. Irwin & Barneby ser. Spinescentes H. S. Irwin & Barneby is restricted to the Neotropical region and has species distributed predominantly in the lowland forest of Amazonia. These species are morphologically distinguished by their scandent or viny habit, stipular thorns, and laterally compressed fruit...

The new species Eugenia stenocarpa Valdemarin & A.Maruy. is described and illustrated. It is nested within Eugenia sect. Speciosae but is distinguished from other species in the section by the combination of its sparsely puberulent and glabrescent young twigs, revolute leaf margin with a thickened yellow edge, flowers with pubescent hypanthium, and...

Caesalpinioideae is the second largest subfamily of legumes (Leguminosae) with ca. 4680 species and 163 genera. It is an ecologically and economically important group formed of mostly woody perennials that range from large canopy emergent trees to functionally herbaceous geoxyles, lianas and shrubs, and which has a global distribution, occurring on...

Senna ser. Bacillares (Leguminosae, Cassieae) is the largest of the American Senna series, with approximately 50 species. Several taxa are still poorly known or with problematic delimitation. Based on extensive fieldwork and collection-based research for our ongoing taxonomic studies on Senna ser. Bacillares, we identified two new species which we...

Chamaecrista is one of the largest genera of Leguminosae, subfamily Caesalpinioideae. Traditionally, it has been divided into six sections, of which Chamaecrista sect. Absus is the largest, with 31 series. Chamaecrista sect. Absus ser. Setosae comprises nine species. Chamaecrista setosa is the most widely distributed species, comprising four variet...

Copaifera L. is a tropical genus with its highest diversity in the New World, renowned for the "copaiba oil" extracted from the trunk of many of its species, which has wide applications in traditional medicine and the pharmachemical industry. Despite relatively recent revisions, the genus is still deemed complex and its species difficult to recogni...

Non-monophyly is a prominent issue in mimosoid legumes, even in some of the less speciose genera such as the neotropical genus Stryphnodendron. This genus includes 35 species occurring from Nicaragua to Southern Brazil mostly in humid forests and savannas. Previous taxonomic studies of Stryphnodendron have highlighted morphologically distinct group...

Stryphnodendron is a Neotropical genus of Fabaceae (Caesalpinioideae, mimosoid clade), comprising 36 taxa occurring from Nicaragua to Southern Brazil, most of them found and endemic in Brazil, being especially frequent in savannas (Cerrado) and the Amazon Forest. This synopsis presents the designation of 16 lectotypes, eight new synonyms, a new com...

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...

Senna (Leguminosae, Cassiinae) is a speciose genus widely distributed throughout tropical and subtropical regions of the world. During taxonomic studies of Senna sect. Chamaefistula ser. Bacillares , a new endemic and endangered species from the Atlantic Forest of Bahia,Brazil was discovered. The new species, Senna bahiensis , is compared with its...

Pombalia Vand. (Violaceae) is represented in the Cerrado by a well-supported monophyletic group of species known as the Pombalia lanata complex, characterised by some unique vegetative and reproductive features within the genus. This group includes six species-Pombalia cristalina, P. insignis, P. lanata, P. poaya, P. strigoides and P. velutina-the...

During a taxonomic treatment of Stryphnodendron (Leguminosae, Caesalpinioideae, mimosoid clade) for the Brazilian Flora 2020 Project, one new presumably critically endangered species from the Atlantic Forest domain was found, and is so far only known to western Espírito Santo state. Stryphnodendron flavotomentosum is described and illustrated, and...

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...

Copaifera L. is a pantropical genus with great diversity in the Cerrado. Fieldwork in western São Paulo revealed the first record of C. malmei Harms in this state, and this is only the second time that this species has been found in the Southeast Region of Brazil. Additional analyses of a related species, C. marginata Benth. revealed the same rare...

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...

O Herbário ESA, do Departamento de Ciências Biológicas da Escola Superior de Agricultura " Luiz de Queiroz " – USP, está situado no município de Piracicaba/SP, e teve seu começo no início do século XX, embora sua consolidação tenha ocorrido por volta dos anos 1980. Atualmente, o Herbário ESA apresenta uma coleção com cerca de 170.000 espécimes de p...

The Artemisia annua L. is a source of essential oils used in perfumery and cosmetics industry, and the yield of oil is affected by the quality of the seedlings used. The present study was carried out in order to evaluate the production of Artemisia annua L. seedlings grown in greenhouse, under two irrigation systems and four levels of commercial fe...
