摘要

Myrcia sect.Eugeniopsis是Myrcia科（Myrciinae，Myrteae，桃金娘科）的九个分支之一，包括目前同义属Eugeniopsis的大部分物种。通过实地考察和对标本馆藏品的分析，我们在此描述了该科的一个新物种 Myrcia tenondeporan，它是 Serra do Mar 山区大西洋森林的特有种。该新种与 Myrcia vellozoi 和 Myrcia multipunctata 有亲缘关系，但主要在叶片形状和大小、花序结构和花蕾大小方面存在差异。

Myrcia tenondeporan, a new species of Myrtaceae from the Atlantic Forest in the Serra do Mar Mountains, Brazil

Myrcia sect. Eugeniopsis is one of the nine sections of Myrcia (Myrciinae, Myrteae, Myrtaceae) and includes mostly species of the current synonym genus Eugeniopsis. Using fieldwork and the analysis of herbarium collections as a basis, we describe here a new species of this section, Myrcia tenondeporan, which is endemic to the Atlantic Forest in the Serra do Mar Mountains. The new species is related to Myrcia vellozoi and Myrcia multipunctata but differs mainly in the leaf shape and size, inflorescence structure and size of floral buds.

期刊介绍： Phytotaxa is a peer-reviewed, international journal for rapid publication of high quality papers on any aspect of systematic and taxonomic botany, with a preference for large taxonomic works such as monographs, floras, revisions and evolutionary studies and descriptions of new taxa. Phytotaxa covers all groups covered by the International Code of Nomenclature foralgae, fungi, and plants ICNafp (fungi, lichens, algae, diatoms, mosses, liverworts, hornworts, and vascular plants), both living and fossil. Phytotaxa was founded in 2009 as botanical sister journal to Zootaxa. It has a large editorial board, who are running this journal on a voluntary basis, and it is published by Magnolia Press (Auckland , New Zealand). It is also indexed by SCIE, JCR and Biosis. All types of taxonomic, floristic and phytogeographic papers are considered, including theoretical papers and methodology, systematics and phylogeny, monographs, revisions and reviews, catalogues, biographies and bibliographies, history of botanical explorations, identification guides, floras, analyses of characters, phylogenetic studies and phytogeography, descriptions of taxa, typification and nomenclatural papers. Monographs and other long manuscripts (of 60 printed pages or more) can be published as books, which will receive an ISBN number as well as being part of the Phytotaxa series.
