The phylogenetic tree of Camellia species based on the complete cp genomes (complete cp-Tree). Coffea canephora and Coffea arabica were selected as the outgroup. Tree were constructed by neighbor-joining (NJ), maximum parsimony (MP), Bayesian inference (BI) and maximum likelihood (ML) with bootstrap values or posterior probabilities above the branches, respectively. Bootstrap values less than 50% are represented by "-". As indicated in the legend at the top left, the unique genes and introns of each species were plotted onto branches using colored squares
