Abstract
Abstract A taxonomic study of Cyperus L. (Cyperaceae) in the Central-West region of Brazil is presented. We examined more than 1300 herbarium specimens. Many of the species were also studied in the field. Our results recognize 59 species of Cyperus in the Central-West of Brazil, including three species endemic to the country that are potentially threatened with extinction, i.e., C. hooperae G. C. Tucker, C. longiculmis Pereira-Silva, Hefler & R. Trevis., and C. tuckerianus Pereira-Silva, Hefler & R. Trevis. Cyperus oxylepis Nees ex Steud. is reported from Brazil for the first time. Cyperus incomtus Kunth var. miguelii Kük. is proposed as a synonym of C. pearcei C. B. Clarke. We designate lectotypes for 20 names, a neotype for C. oxylepis, and an epitype for C. surinamensis Rottb. and select second-step lectotypes for 10 names. We also provide detailed morphological descriptions, illustrations, distribution data, an identification key for all species, and assessments of the conservation status for most species.
摘要对巴西中西部地区苏柏属(Cyperus L.)进行了分类研究。我们检查了1300多个植物标本室标本。许多物种也在野外进行了研究。结果表明，巴西中西部地区共有59种塞柏属植物，其中3种为巴西特有物种，即C. hooperae G. C. Tucker、C. longiculmis Pereira-Silva、Hefler & R. Trevis。C. tuckerianus Pereira-Silva, Hefler & R. Trevis。苏柏属植物。首次从巴西报道。香柏草(Cyperus incomtus Kunth)变种miguelii k。被认为是C. pearcei C. B. Clarke的同义词。我们指定了20个名称的选型，一个新类型为C. oxylepis，一个表型为C. surinamensis Rottb。并为10个名称选择第二步lectotypes。我们还提供了详细的形态描述，插图，分布数据，所有物种的识别密钥，以及大多数物种的保护状况评估。
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.
