Abstract

This study proposes a new species of Eugenia sect. Phyllocalyx from Atlantic Forest remnants in the Brazilian state of Rio de Janeiro. The new taxon, Eugenia guapiassuana, is proposed based on literature survey, examination of herbarium material and field work. We herein provide a morphological description, including comments on fruit taste, along with information on distribution, habitat, phenology, vernacular name, taxonomy and conservation status. Figures showing fresh and dry material and a map of the occurrence records are also presented. Eugenia guapiassuana is morphologically similar to E. involucrata and E. superba, and these species are contrasted in the discussion. Following an assessment, the conservation status of Eugenia guapiassuana is provisionally determined as Critically Endangered [CR B2ab(iii)].

Eugenia guapiassuana(桃金娘科)--巴西大西洋森林中一个引人注目的新树种
本研究从巴西里约热内卢州的大西洋森林残余物中发现了 Eugenia sect.Phyllocalyx 的一个新种。新分类群 Eugenia guapiassuana 是根据文献调查、标本馆材料检查和野外工作提出的。我们在此提供形态描述,包括对果实味道的评论,以及有关分布、栖息地、物候学、方言名称、分类学和保护现状的信息。图中还展示了新鲜和干燥的材料,以及出现记录的地图。Eugenia guapiassuana在形态上与E. involucrata和E. superba相似,讨论中对这两个物种进行了对比。经过评估,Eugenia guapiassuana 的保护地位暂定为极危[CR B2ab(iii)]。
