Integrative Conservation, EarlyView.Accurate species identification is critical for conserving endangered Firmiana trees in China. However, morphological similarities among closely related Firmiana species complicate its taxonomic identification. We conducted genome skimming on 62 samples representing all 10 Chinese species and discovered nrITS as the optimal DNA barcode, achieving 100 ...
