摘要

摘要Citharexylum L.与Rehdera Moldenke同属马鞭草科Cithareyleae。它包括生长在新热带地区的大约50到60种树木和灌木。本文首次对南美洲Citharexylum进行了完整的分类学修订。南美洲有30个分类群，其中27个是地方性的，其中3个也生长在中美洲。每个分类单元都有详细的形态学描述，以及识别它们的关键；插图、照片或图像；更新同义词；地理分布图和生态笔记；选定标本清单；以及关于亲缘类群之间关系的讨论。一个新的身份，C.poeppigii Walp。提出了一个新组合C.dentatum D.Don var.canescens（Moldenke）N.O'Leary。提出了35个新的同义词，并为C.fruticosum L.var.brittonii（Moldenke）I.E.Méndez、C.laurifolium Hayek和Rauvolfia spinosa Cav指定了选型。

Insights into the Taxonomy of Citharexylum (Verbenaceae): A Revision of the South American Taxa

Abstract Citharexylum L. belongs to the recently circumscribed tribe Citharexyleae of the Verbenaceae, along with Rehdera Moldenke. It comprises around 50 to 60 species of trees and shrubs growing in the Neotropics. A complete taxonomic revision of Citharexylum in South America is here provided for the first time. Thirty taxa are present in South America, 27 of these are endemic, and three of them also grow in Central America. Detailed morphological descriptions are given for each taxon, as well as a key for their identification; illustrations, photographs, or iconography; updated synonymy; geographic distribution maps and ecological notes; list of selected specimens; and discussion about the relationship among closely related taxa. A new status, C. poeppigii Walp. var. anomalum (Moldenke) N. O'Leary, and a new combination, C. dentatum D. Don var. canescens (Moldenke) N. O'Leary, are proposed. Thirty-five new synonyms are suggested, and lectotypes are designated for C. fruticosum L. var. brittonii (Moldenke) I. E. Méndez, C. laurifolium Hayek, and Rauvolfia spinosa Cav.

期刊介绍： The Annals of the Missouri Botanical Garden is a quarterly international journal primarily devoted to systematic botany and evolutionary biology. We encourage submissions of original papers dealing with significant advances in the taxonomy, phylogeny, biogeography, paleobiology, and evolution of plants, and in conservation genetics and biology, restoration ecology, and ethnobiology, using morphological and/or molecular characters, field observations, and/or database information. We also welcome reviews and papers on conceptual issues and new methodologies in systematics. Important floristic works will also be considered. Symposium proceedings discussing a broader range of topical biological subjects are also published, typically once a year. All manuscripts are peer-reviewed by qualified and independent reviewers.
