Casearia genus (Salicaceae) is found in sub-tropical and tropical regions of the world comprises about 160-200 species. It a medicinal plant used South America, also known as "guaçatonga", "erva-de-tiú", "cafezinho-do-mato". In Brazil, there are 48 species 12 registered State Rio de Janeiro, including sylvestris Sw. There many studies related to chemical profile cytotoxic activities extracts from these plants, although few antifungal potential essential oil have been reported. this work, we...
Salicaceae possess a range of leaf teeth types, many characterized as nectariferous salicoid or violoid teeth. One large genus, Casearia, deviates from this generalization in having theoid Although taxonomic descriptions Casearia have included reports glands at the apex teeth, there been no their anatomy functional role. Here, we aim to describe 43 spp. Leaf samples herbarium specimens were processed for light and scanning electron microscopy. Leaves C. sylvestris collected fixed field...

Casearia espiritosantensis R. Marquete & Mansano, a new species of Salicaceae from Espírito Santo, Brazil, is described and illustrated here. This similar to the widespread C. decandra Jacq. in having fasciculate inflorescences, lanceolate or elliptic-lanceolate leaves, 10 stamens. The differs by being shrub smaller stipules, anthers with apical glands, hirsute ovaries, clavate stigmas. Other diagnostic aspects are sparsely serrate leaf margins stipules glands at base adaxial surface.
Premise of research. In Casearia Jacq., one the largest genera Salicaceae, stipular glands are taxonomically important, although these structures have not previously been described anatomically. The aims this study were to clarify gland type present on stipules three species and describe anatomical variations in Cerrado forest specimens.Methodology. Samples decandra a typical species; rufescens Cambess., which is endemic Cerrado; sylvestris Sw., occurs both vegetation types, collected....
Field studies and examination of herbarium specimens have led to a taxonomic revision the Casearia ulmifolia Vahl ex Vent. complex (Salicaceae). A new species circumscription is presented for C. ulmifolia, cotticensis Uittien reestablished, one species, murceana R. Marquete & Mansano, described from Pará, Brazil. Morphological descriptions, key, geographical distributions, diagnostic characteristics illustrations are provided.

The "Serra da Concórdia" is part of the Atlantic Forest phytogeographical domain in Brazilian state Rio de Janeiro and it has a predominant phytophysiognomy Semideciduous Seasonal Forest. This region underwent intense habitat loss fragmentation during 19 th century, due to coffee plantations later pastures. With decline these activities, areas were abandoned, triggering secondary succession. In 2002, "Parque Estadual Serra was established this preserve remaining forest fragments. updated...
Abstract ABC transporters constitute a superfamily of transmembrane proteins that act mediating the translocation several substrates across membrane, using energy ATP hydrolysis. This mechanism unrelated efflux (multidrug resistance) has been associated with diseases and it is problem in chemotherapy efficacy. Nowadays, approximately 25% prescription drugs world are derived from plants. Casearia sylvestris commonly found Americas different parts this plant popularly used to treat diseases....
Abstract A new species of Salicaceae growing in the state Espírito Santo and south Bahia, Casearia valenciana R.Marquete & R.B.Torres, is described illustrated here. It similar to C. cotticensis Uittien, which grows further north Amazonian Forest, by its pedunculate inflorescence, coriaceous leaves, glabrous ovary. Yet, it differs from shrub small tree habit (vs. up 27 m tall), smaller stipules, elliptic leaves lanceolate, broadly oblong-lanceolate), elongated anthers with longitudinal...
