From: Biogeography of the Phalaenopsis amabilis species complex inferred from nuclear and plastid DNAs
Ancestral distributions reconstructed by RASP. Phylogenetic relationships of the 39 accessions in the P. amabilis species complex, plus the three outgroups P. schilleriana, P. stuartiana and P. philippinensis, obtained from sequence comparisons of the cpDNA trnH-psbA spacer sequence and generated by BEAST. Bayesian credibility values (PP) are indicated above the branch on one of the post-burn Bayesian trees. The distribution areas of extant accessions of P. amabilis species are marked in capitals A–J (A: Bantam, Java, Indonesia; B: Mentawai Is., Sumatra, Indonesia; C: Brooks Point, Palawan, the Philippines; D: Sabah, Indonesia; E: East Timor; F: Celebes, Molucca Is., Indonesia; G: Kaiser Wilhelms, New Guinea; H: Mindanao, the Philippines; I: Manila, Luzon, Fuga Is., and Calayan Is. in the Philippines; J: southern Taiwan), respectively. The grey circles indicate the vicariance events and the circles with dashed line indicate the long-distance dispersal (LDD) events obtained from the RASP analysis, respectively
