From: Paraphyly of organelle DNAs in Cycas Sect. Asiorientales due to ancient ancestral polymorphisms
The maximum likelihood tree of haplotypes of Cycas revoluta and C. taitungensis with outgroup sequences (O). Numbers at nodes indicate the bootstrap values (ML/MP) in percentage. Symbols in parentheses indicate the geographical distribution of each mitotype. W = widespread. A) mtDNA. Clades A and B occur in both species, while clades D-G are restricted to C. revoluta. B) cpDNA. Clades I, III and IV occur in both species, while other are restricted to C. revoluta.
