摘要

摘要Kaunia R.M.King和H.Rob。是一个由11个物种组成的小属，在安第斯生态系统中发挥着重要作用，无论是通过控制特定的植被单元，还是作为赤杨群落和鹿比诺森林边界的亚优势物种。考尼亚属的物种是灌木或小树，通常有粉红色或白色，通常管状漏斗状的花冠，内部光滑的裂片缺乏乳头，样式均匀宽，有20到26条染色体。由于缺乏对考尼亚属的完整和详尽的研究，因此对其分类学进行了修订。这项工作的结果，加上以前的统计研究，共确认了10种考尼亚属植物。Kaunia ignorata（Hieron.）R.M.King和H.Rob。被置于K.camataquiensis（Hieron.）R.M.King和H.Rob.的同义词之下。，和为霍桑Eupatorium hosanense B.L.Rob的一个选择型。被指定。我们的研究提供了第一个形态和解剖学的考尼亚研究。还提供了物种的钥匙、详细描述、插图和每个物种的分布图。

Taxonomic Revision of Kaunia (Eupatorieae, Asteraceae), an Andean Genus with Presence in Eastern South America1

Abstract Kaunia R. M. King & H. Rob. is a small genus of 11 species that play an important role in Andean ecosystems, either by dominating specific vegetation units or as subdominant species at boundaries of alder communities and pino del cerro forests. The species of Kaunia are shrubs or small trees with commonly pinkish or white, usually tubular-funnelform corollas of internally smooth lobes lacking papillae, uniformly wide styles, and 20 to 26 chromosomes. A complete and exhaustive treatment of Kaunia is lacking, and so its taxonomy is herein revised. As a result of this work, together with those of previous statistical studies, 10 species of Kaunia are recognized. Kaunia ignorata (Hieron.) R. M. King & H. Rob. is placed under synonymy of K. camataquiensis (Hieron.) R. M. King & H. Rob., and a lectotype for Eupatorium hosanense B. L. Rob. is designated. Our study provides the first morphological and anatomical study of Kaunia. A key to the species, detailed descriptions, illustrations, and distribution maps for each species are also provided.

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.
