Abstract Adiantum × meishanianum F. S. Hsu ex Y. C. Liu & W. L. Chiou was regarded as an endemic species in Meishan Village, Kaohsiung, Taiwan, China and a hybrid between A. malesianum Ghatak (the maternal parent) sexually reproducing diploid cryptic of philippense paternal parent), revealed by chloroplast nuclear markers. However, morphological research that is also disjunctively distributed Yunnan its parent possibly menglianense Qian. Thus, this study aimed to confirm these findings using two regions low‐copy marker DNA barcoding phylogenetic analyses, spore measurement, flow cytometry. Our results indicated triploid abortive, the same they both originated from hybridization , but not . In conclusion, probably multiple hybridizations Taiwan Yunnan.
