This work presents a checklist of the Bromeliaceae in Serra do Conduru State Park (PESC), in the Atlantic Forest of the state of Bahia, Brazil, including data on their growth habit, endemism and conservation status. We also describe and illustrate a new species, that is endemic to the area studied and classified by us as critically endangered. The data were collected through field expeditions, analysis of herbarium material and review of the specialized literature. We found 70 species of Bromeliaceae distributed in 20 genera of the subfamilies Bromelioideae (48 spp.) and Tillandsioideae (22 spp.). The diversity of Bromeliaceae in the PESC is the greatest recorded to date in a conservation unit or forest fragment in Brazil. The species studied have a variety of life forms, with 52 spp. being exclusively epiphytic, 7 terrestrial and 11 species occurring in either of these forms. With regard to conservation status, four species are classified as critically endangered, nine as endangered and seven as vulnerable according to the IUCN criteria. In relation to endemism, 33 species are endemic to Bahia (47%), more specifically 31 spp. to the southern region of the state, and three species are microendemic ( and ) so far only observed within the PESC. Our results demonstrate that the southern region of Bahia has high diversity in comparison with other regions of the state and also of Brazil. These findings also reveal the scientific value of the PESC and the need for further research conservation and efforts of this region.

凤梨科的微特有现象、高度多样性和分类学新颖性：来自巴西巴伊亚大西洋森林热点地区的研究

这项工作提供了巴西巴伊亚州大西洋森林 Serra do Conduru 州立公园 (PESC) 的凤梨科植物清单，包括其生长习性、特有现象和保护状况的数据。我们还描述和说明了一种新物种，它是我们研究并归类为极度濒危地区的特有物种。数据是通过实地考察、植物标本分析和专业文献回顾收集的。我们发现了 70 种凤梨科植物，分布在凤梨亚科（48 种）和铁兰亚科（22 种）的 20 属中。PESC 中凤梨科的多样性是巴西保护单位或森林片段中迄今为止记录最多的。研究的物种有多种生命形式，有 52 种。完全是附生植物，有 7 种陆生植物和 11 种植物以这两种形式出现。在保护状况方面，根据国际自然保护联盟的标准，​​有四个物种被列为极度濒危物种，九个物种被列为濒危物种，七个物种被列为脆弱物种。就特有性而言，33 个物种是巴伊亚特有物种（47%），更具体地说是 31 个物种。该州南部地区有 3 个物种为微地方病 ( 和 )，迄今为止仅在 PESC 内观察到。我们的结果表明，与该州其他地区以及巴西相比，巴伊亚南部地区具有高度多样性。这些发现还揭示了 PESC 的科学价值以及该地区进一步研究保护和努力的必要性。
