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.
