<em>Paepalanthus roqueae</em>: A new critically endangered Eriocaulaceae in campo rupestre of Chapada Diamantina, Bahia, Brazil
收藏资源简介:
Here we describe a new species of Paepalanthus (Eriocaulaceae) from the Chapada Diamantina, in the northern part of the Espinhaço Range in Brazil. The study aims to contribute to the knowledge of Eriocaulaceae in this area, which has a significant knowledge gap, and to provide a comparison with other poorly understood species in the region. The new species, named Paepalanthus roqueae, is described in detail, including morphological measurements, illustrations, and distribution maps. Its conservation status is also evaluated using IUCN criteria. This paper emphasizes the importance of botanical research in the high biodiversity area of Chapada Diamantina, to increase the knowledge of poorly understood species and promote conservation efforts., , , # Data from: *Paepalanthus roqueae*: A new critically endangered Eriocaulaceae in campo rupestre of Chapada Diamantina, Bahia, Brazil Dataset DOI: [10.5061/dryad.8kprr4xxf](https://doi.org/10.5061/dryad.8kprr4xxf) ## Description of the data and file structure *Paepalanthus roqueae*: a new critically endangered Eriocaulaceae in campo rupestre of Chapada Diamantina, Bahia, Brazil.

我们在此记述一种产自巴西埃斯皮尼亚苏山脉北部查帕达·迪亚曼蒂纳地区的头花谷精属(Paepalanthus)新种(谷精草科(Eriocaulaceae))。本研究旨在填补该区域谷精草科研究的显著空白,深化对该类群的认知,并与区域内其他研究不足的类群开展对比分析。该新种被命名为罗克氏头花谷精(Paepalanthus roqueae),文中对其进行了详细记述,包括形态测量数据、形态图及分布地图,并依据国际自然保护联盟(IUCN)标准评估了其保护等级。本文强调了查帕达·迪亚曼蒂纳这一高生物多样性区域开展植物学研究的重要性,以深化对研究不足类群的认知并推动保护工作。 # 数据来源:*罗克氏头花谷精(Paepalanthus roqueae):巴西巴伊亚州查帕达·迪亚曼蒂纳岩原稀树草原(campo rupestre)极危谷精草科新种* 数据集DOI: [10.5061/dryad.8kprr4xxf](https://doi.org/10.5061/dryad.8kprr4xxf) ## 数据与文件结构说明 *罗克氏头花谷精(Paepalanthus roqueae):巴西巴伊亚州查帕达·迪亚曼蒂纳岩原稀树草原极危谷精草科新种*.
