The orchid tribe   Tropidieae   comprises three genera,    Tropidia   ,    Corymborkis    and    Kalimantanorchis   . There are three fully mycoheterotrophic species within   Tropidieae  :    Tropidia   saprophytica   ,    T.   connata    and    Kalimantanorchis   nagamasui   . A previous phylogenetic study of    K.   nagamasui   , based only on plastid  matK  data, placed    K.   nagamasui    outside the clade of    Tropidia    and    Corymborkis    without support. In this study, we performed phylogenetic analyses using a nuclear ribosomal DNA spacer (ITS1-5.8S-ITS2), a low-copy nuclear coding gene ( Xdh ) and a mitochondrial intron ( nad1b-c  intron) to study the phylogenetic relationships within   Tropidieae  . We included six photosynthetic and all three fully mycoheterotrophic   Tropidieae   species. The resulting phylogenetic trees placed these fully mycoheterotrophic species inside the    Tropidia    clade with high support. In our trees, these three species do not form a monophyletic group together, because the photosynthetic    T.   graminea    is nested amongst them. Our results also suggest that the loss of photosynthetic ability occurred at least twice in    Tropidia   .
