The ML consensus tree of Manglietia based on three molecular markers (PHYA, LEAFY, and trnH-psbA).
Note: The topolopy of the MP tree is congruent with the ML tree. Numbers above and below the branches are ML maximum parsimony bootstrap values (BS) and MP maximum parsimony bootstrap values (BS), respectively. [] shows the tree of ML and MP conflicts in the node.
