Abstract

Plinia renatiana is a species endemic to the state of Espírito Santo (ES) and has been assessed as endangered (EN). The species was described in the 1990s based on two samples from the municipality of Linhares. Subsequently, other materials were identified as belonging to the species. However, this set of materials exhibits heterogeneous morphology, which raises doubts about the correct name application. Therefore, it was necessary to expand the species description by incorporating new field-collected data and analyzing a greater number of herbarium specimens. In this study, we analyzed materials deposited in herbaria identified as P. renatiana, reviewed the literature, and conducted field surveys. Based on the collected data, we have expanded the morphological description and reassessed its extinction risk. In addition to the morphological description, taxonomic comments, phenology, a distribution map, and illustrations are provided. In our reassessment, the species was categorized as EN (A2c; B1(i,iii,v) + 2ab(ii,iii,v)), with changes to the criteria used in the 2012 assessment. Despite the review and inclusion of new data, the species has remained in the same threat category in which it was assessed more than a decade ago, underscoring the need for conservation efforts.

重新描述和评估巴西圣埃斯皮里图州特有物种 Plinia renatiana（桃金娘科）的灭绝风险

Plinia renatiana是圣埃斯皮里图州（ES）的特有物种，已被评估为濒危物种（EN）。20 世纪 90 年代，根据林哈雷斯市的两个样本对该物种进行了描述。随后，其他材料也被确认属于该物种。然而，这组材料呈现出不同的形态，令人怀疑其名称是否正确。因此，有必要通过纳入新的野外采集数据和分析更多标本馆标本来扩展物种描述。在这项研究中，我们分析了标本馆中保存的被认定为 P. renatiana 的材料，查阅了文献，并进行了实地调查。根据收集到的数据，我们扩充了形态描述，并重新评估了其灭绝风险。除了形态描述外，我们还提供了分类评论、物候学、分布图和插图。在我们的重新评估中，该物种被归类为EN（A2c；B1（i,iii,v）+ 2ab（ii,iii,v）），与2012年评估中使用的标准有所变化。尽管进行了审查并纳入了新数据，但该物种仍处于十多年前评估时的威胁类别，这凸显了保护工作的必要性。

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.
