Phylogenetic description of the genus Alpinia

Alpinia is, phylogenticaly the most complex group of zingiberaceae which is accounted by numerous ecotypes, low level of variation among the plastid genes and large taxa size. The phylogeny based on the sequences from the species which were collected and described here has two distinct clusters. The close clustering of Alpinia species1 and species3 inkles that they could be same and since they have clustered distinctly from other members of its cluster hence probably it is a distinguished species.

The evolutionary history based on the plastid gene matK and psbA-trnH in concatenation, inferred using the Neighbor-Joining method. The evolutionary distances were computed using the Kimura 2-parameter method.
