Abstract
A phylogeny of Phalaenopsis was reconstructed using three chloroplast markers, matK, atpH-atpF, and trnO-trnE, totaling 2177 base pairs. Results of Bayesian and Maximum Parsimony analyses support the placement of the species of Doritis and Kingidium into a more broadly defined Phalaenopsis, as proposed in a revision of the genus by Christenson. While some of Christenson's subgeneric groups appear to be monophyletic, several species may need to be reclassified, if a natural classification is desired. Taxon sampling, however, must be completed, and the identities of several plants confirmed, before definitive conclusions can be made. Another marker of approximately 1300 base pairs will be added to the analysis. It is expected to provide more support and to improve the resolution of the tree, especially at the basal nodes and in the subgenus Polychilos.
