Gastrodia bawanglingensis, a new species of Orchidaceae from Hainan Island, China, is described and illustrated. It is morphologically similar toG. theana,G. albidoidesandG. albidawith dwarf habits, scarcely opening flowers, elongated fruit stems, curved and fleshy perianth tubes and similar columns and lips, but can be easily distinguished from them by having a pair of lateral wings bent outwards at the apex of the column and lateral wings with acuminate tips lower than the anther. According to the IUCN Red List Categories and Criteria, the new species is assessed as Endangered (EN). The plastome ofG. bawanglingensisis greatly reduced and reconfigured with approximately 30876 bp in size and 25.36% in GC content. Morphological characteristics and molecular phylogenetic results based on chloroplast gene sequences support the recognition ofG. bawanglingensisas a new species withinGastrodia.
