A maximum likelihood (ML) tree of Orchidaceae indicating the phylogenetic position of Habenaria radiata. The ML tree is reconstructed from the sequences of 78 protein coding genes and four rRNA genes for 41 plastome sequences. The number above or below of each node indicates bootstrap supporting value from 100 replications.
