Understanding of intercontinental distribution in the Northern Hemisphere has attracted a lot of attention from botanists. However, although Orchidaceae is the largest group of angiosperms, biogeographical studies on the disjunctive pattern have not been sufficient for this family. Goodyera R. Br. (tribe Cranichideae, subfamily Orchidoideae, family Orchidaceae) is widely distributed in temperate and tropical regions. Although the phylogenetic relationship of Goodyera inferred from both morphological and molecular data has been conducted, the sampled taxa were mainly distributed in Asia regions that resulted in non-monophyly of this genus. In this study, the complete plastid genomes of Goodyera, generated by next-generation sequencing (NGS) technique and sampled in East Asia and North America, were used to reconstruct phylogeny and explore the historical biogeography. A total of 18 Goodyera species including seven newly sequenced species were analyzed. Based on 79 protein-coding genes, the phylogenetic analysis revealed that Goodyera could be subdivided into four subclades with high support values. The polyphyletic relationships among Goodyera taxa were confirmed, and the unclear position of G. foliosa was also resolved. The datasets that are composed of the 14 coding sequences (CDS) (matK, atpF, ndhK, accD, cemA, clpP, rpoA, rpl22, ndhF, ccsA, ndhD, ndhI, ndhA, and ycf 1) showed the same topology derived from 79 protein-coding genes. Molecular dating analyses revealed the origin of Goodyera in the mid-Miocene (15.75 Mya). Nearctic clade of Goodyera was diverged at 10.88 Mya from their most recent common ancestor (MRCA). The biogeographical reconstruction suggests that subtropical or tropical Asia is the origin of Goodyera and it has subsequently spread to temperate Asia during the Miocene. In addition, Nearctic clade is derived from East Asian species through Bering Land Bridge (BLB) during the Miocene. The speciation of Goodyera is most likely to have occurred during Miocene, and climatic and geological changes ...
