Abstract

Abstract: An ongoing taxonomic revision of neotropical Connarus has identified three undescribed species of the genus, which are published here. One of them, C. foreroi, is known only from a single gathering from central Peru, probably reflecting scarcity of botanical inventories. Connarus revolutus, on the other hand, seems to be more common, but it is restricted to northeastern Espírito Santo and southern Bahia, Brazil. Connarus pedicellatus, originally described as a variety of C. erianthus, is elevated to the rank of species; it is distributed widely in the Amazon forest of Brazil, extending to southern Suriname. The present study describes and illustrates these three new species and provides a geographic distribution map, comparisons, information on habitat, phenology and preliminary conservation risk assessments, along with a key to distinguish them from similar taxa.

Version of record first published online on 9 June 2021 ahead of inclusion in August 2021 issue.

新热带姜属植物(姜属科)的分类修订鉴定了三个未被描述的种

摘要/ Abstract摘要:一项正在进行的新热带小豆属(netropical Connarus)的分类修订发现了该属的三个未描述种，并在此发表。其中一种，C. foreeroi，只在秘鲁中部的一次采集中被发现，可能反映了植物库存的稀缺。另一方面，似乎更常见的是康纳鲁斯，但它仅限于Espírito圣东北部和巴西巴伊亚州南部。原描述为C. erianthus变种的Connarus pedicellatus被提升到种的等级;它广泛分布在巴西的亚马逊森林，延伸到苏里南南部。本研究对这三个新种进行了描述和图解，并提供了地理分布图、比较、生境、物候信息和初步保护风险评估，以及与相似分类群区分的关键。引用本文:Toledo C.

期刊介绍： Willdenowia is an international peer-reviewed journal publishing original research articles in English from the entire fields of plant, algal and fungal systematics, covering the evolution, taxonomy and nomenclature of these organisms as well as related fields such as floristics and plant geography. Articles on phylogeny and molecular systematics are especially welcome, as are review articles. Descriptions of new taxa may be considered, but only if supported by robust evidence. Narrowly regional studies of widespread taxa, routine typifications, checklists and new floristic records are generally not considered (excluding contributions to the Euro+Med-Checklist Notulae). Authors are encouraged to deposit duplicates of their material, especially nomenclatural types, in the Berlin herbarium (B).
