dc.description.abstract Baccharis uncinella DC. belongs to the Asteraceae family and is included in the Spicata group. Its synonym is Baccharis discolor Baker and it is popularly known as vassoura and vassoura-lageana in Portuguese. The phytochemical screening has shown the presence of essential oil, flavonoids, alkaloids, cardiac glycosides and saponins. Baccharis uncinella has presented antiviral activity against Herpes simplex type I. The volatile oil of the aerial organs has exhibited antimicrobial action against Staphylococcus aureus, Escherichia. coli and Pseudomonas aeruginosa. This paper has aimed to analyse the morphology and anatomy of the vegetative aerial organs of B. uncinella, in order to supply information for the identification and differentiation of this species from other Baccharis, as well as to expand knowledge on taxonomy of the Spicata group. The botanical material was prepared according to standard light and scanning electron microscopic techniques. The morpho-anatomical characters of the leaf and stem contribute to the identification of this species. en
dc.description.abstract Baccharis uncinella DC. pertence à família Asteraceae e está incluída no grupo Spicata. Apresenta como sinonímia Baccharis discolor Baker e é conhecida popularmente como vassoura e vassoura-lageana, em português. O perfil fitoquímico mostrou a presença de óleo essencial, flavonóides, alcalóides, glicosídeos cardiotônicos e saponinas. Baccharis uncinella apresentou atividade antiviral contra Herpes simplex do tipo I. O óleo essencial das partes aéreas exibiu atividade antimicrobiana contra Staphylococcus aureus, Escherichia coli e Pseudomonas aeruginosa. Este trabalho objetivou analisar a morfologia externa e a anatomia das partes vegetativas aéreas, com a finalidade de obter dados referentes à identificação e à diferenciação dessa espécie das demais Baccharis, além de fornecer dados taxonômicos ao grupo Spicata. O material botânico foi submetido às microtécnicas fotônicas e eletrônicas de varredura usuais. As características morfoanatômicas descritas para a folha e o caule auxiliam na identificação da espécie. pt
