description: TABLE 1. Meistera species in Cambodia, Laos and Vietnam and their spot characters with the most distinctive character states in bold (AC—anther crest; FR—fruit; LA—labellum; LB—Leaf blades; LI—ligule; LS—leaf sheaths). The characters and the distribution are mainly based on information from Lamxay & Newman (2012), and supplemented with information from protologues and other works cited in Introduction.
