Contribuição à taxonomia de Marlierea (Myrciinae; Myrtaceae) no Brasil

Abstract

ResumoApresenta-se uma circunscrição taxonômica de Marlierea e três novos registros de ocorrência para o gênero na Amazônia brasileira, sendo dois para o Brasil, três para o estado do Pará e um para o estado do Amazonas. Comentários sobre características diagnósticas e afinidades taxonômicas de cada espécie, bem como os respectivos dados de distribuição geográfica e ambientes típicos de ocorrência são também fornecidos. Recomendações para atualização da lista de espécies de Myrtaceae da flora do Brasil também são apresentadas. Palavras-chave: Amazônia, circunscrição taxonômica, fitofisionomia, morfologia, novos registros. AbstractThis paper presents a taxonomic circumscription of Marlierea and three new records of occurrence for the genus in the Brazilian Amazon, two in Brazil, three for the State of Pará and one for the State of Amazonas. Comments on the morphology and affinity of taxa are provided to facilitate recognition of each species, as well as their geographical distribution data and typical environments occurrence of these species in the Amazon region. Recommendations for updating the list of Brazilian Myrtaceae species are presented.

Constituents and Pharmacological Activities of Myrcia (Myrtaceae): A Review of an Aromatic and Medicinal Group of Plants

“…and Gomidesia O.Berg), comprising 753 species [1], that are now in process of synonimization based on recent molecular findings [6,7,8]. According to Rosario and coworkers, many species of these four genera found in the Amazon still need phylogenetic analysis [9]. …”

Taxonomic studies of Myrcia (Myrciinae, Myrtaceae) in Brazil: morphological novelties, circumscriptions, and new records for the Amazon

“…However, this characterization was not adopted in the present study, as we followed the proposal of Rosário (2012), who described the morphologies of the floral buds of Myrciinae based primarily on calyx dehiscence. This author, and Rosário et al (2014aRosário et al ( , 2014b, concluded that these features are the most diagnostic for distinguishing between Calyptranthes, Marlierea, and Myrcia and, in practice, very useful in the systematics of Amazonian species. It is noteworthy, on the other hand, that, disregarding these characteristics of the calyx and accepting that these taxa constitute a single monophyletic generic entity (as has been suggested by Lucas et al 2007Lucas et al , 2011, all the species belonging to these genera should be subordinated to Calyptranthes by the rule of priority, as was pointed out by Rosário et al (2014b).…”

“…The abbreviations of the authors' names and the genera and species follow Brummitt & Powell (1992). Species identifications were performed with the aid of the specialized literature (Amshoff 1948;Holst et al 2003;Souza et al 1999;McVaugh 1958McVaugh , 1969Rosário et al 2005Rosário et al , 2014aRosário et al , 2014bRosário & Secco 2006, 2013, using material identified by experts, type specimens, photographs and/or scanned images, as well as consultations with Myrtaceae specialists. We analyzed material from the study areas and, when necessary, additional collections were consulted.…”

“…According to McVaugh (1958), and Rosário et al (2014aRosário et al ( , 2014b, Calyptranthes and Marlierea are well known in South America, and distinguishable primarily by a dehiscent calyx and the exposure of the corolla in the fl oral bud (pre-anthesis): dehiscent calyx and exposed corolla in Myrcia and Gomidesia; and indehiscent calyx and enclosed corolla in Calyptranthes and Marlierea.…”

Seven new records of Myrtaceae in Brazil

“…Additionally, there is a scarcity of recent taxonomic studies on Myrtaceae of northern Brazil. Souza (1999) studied the Myrtaceae of the Reserva Florestal Adolpho Ducke in Manaus, Amazonas, and Rosário and collaborators provided occasional contributions to the knowledge of the family in the Amazonian biome (Rosário and Secco 2006;Rosário et al 2005Rosário et al , 2013Rosário et al , 2014aRosário et al , 2014b. Most identifications of Brazilian specimens must still rely on extra-Brazilian treatments such as the studies of McVaugh (1958McVaugh ( , 1969 and Holst et al (2002).…”
