ABSTRACT
This article was aimed to study the species identification capability of psbA-trnH among Guanzhong herbs from Dryopteri. The nucleotide sequence information of psbA-trnH region was abstracted using standardized manners from 9 Dryopteri species (19 samples). The identification efficiency of psbA-trnH was analyzed based on TaxonGap among both tested materials (9 species, 19 samples) and tested materials plus GenBank data (17 species, 44 samples in total). The results showed that with the expanded species range, the discriminative efficiency of psbA-trnH de-clined from 100% (9/9) to 82.4% (14/17), while the proportion of within-specific heterogeneity larger than between-specific separability increased from 11.1% (1/9) to 52.9% (9/17). It was concluded that psbA-trnH can be recom-mended as the valuable barcode for homonym distinguishment among Guanzhong herbs, with attention of adequate sampling within species.
