Fig. 5: The phylogenetic and biogeographical analyses of the Dendrobium genus.

a Geographical distribution areas of the Dendrobium genus, illustrating the inferred migration routes of ancient Dendrobium. Area A represents mainland Asia, B represents Malaysia, Sumatra and Borneo, C represents the Philippines, D represents Sulawesi Island, and E represents New Guinea and Australian regions. Map data was sourced from the Database of Global Administrative Areas (gadm.org) and illustrated by QGIS (3.36.1). b Divergence time estimation and biogeographical analysis of the Dendrobium genus, highlighting key divergence events and their corresponding timelines. Species marked with a red star are Dendrobium species with genomes assembling this study. c Analysis of evolutionary rates across the Dendrobium genus, presenting variations in diversification rates among different lineages. d Reticulate network analysis depicting the evolutionary relationships among branches of the Dendrobium genus, illustrating both direct and internal reticulate connections.
