Lomas formations or "fog oases" are islands of vegetation in the desert belt of the west coast of South America, with a unique vegetation composition among the world's deserts. However, plant diversity and conservation studies have long been neglected, and there exists a severe gap in plant DNA sequence information. To address the lack of DNA information, we conducted field collections and laboratory DNA sequencing to establish a DNA barcode reference library of Lomas plants from Peru. This database provides 1,207 plant specimens and 3,129 DNA barcodes data corresponding with collections from 16 Lomas locations in Peru, during 2017 and 2018. This database will facilitate both rapid species identification and basic studies on plant diversity, thereby enhancing our understanding of Lomas flora's composition and temporal variation, and providing valuable resources for conserving plant diversity and maintaining the stability of the fragile Lomas ecosystems.
洛马斯地貌或“雾绿洲”是南美洲西海岸沙漠带中的植被岛屿，具有世界沙漠中独特的植被组成。然而，植物多样性和保护研究长期以来一直被忽视，植物 DNA 序列信息存在严重的缺口。为了解决 DNA 信息的缺乏，我们进行了实地采集和实验室 DNA 测序，建立了来自秘鲁的洛马斯植物 DNA 条形码参考文库。该数据库提供了 1207 个植物标本和 3129 个 DNA 条形码数据，对应于 2017 年和 2018 年在秘鲁的 16 个洛马斯地区进行的采集。该数据库将有助于快速鉴定物种和开展植物多样性的基础研究，从而增进我们对洛马斯植物区系组成和时间变化的了解，并为保护植物多样性和维持脆弱的洛马斯生态系统的稳定性提供宝贵的资源。
