Abstract

The taxonomic status of Hayata Aver. has long been a subject of debate, with confusion and uncertainty regarding its relationship to Zeuxine Lindl. and Cheirostylis Blume. Here, we conducted phylogenetic analyses using complete plastome data and a combination of traditional molecular markers (nrITS, matK, psaB, rbcL and trnL-trnF). Both plastid and nuclear datasets consistently resolved Hayata as sister to Zeuxine, with strong support from plastid data and moderate support from nrITS. Our results support the recognition of Hayata as an independent genus, distinct from both Zeuxine and Cheirostylis.
