Chronogram of Hydrocharitaceae inferred from combined 18S + rbcL + matK + trnK 5’ intron + rpoB + rpoC1 + cob + atp1 sequence data using BEAST. Three calibration points are indicated with blank asterisks. Grey boxes indicate 95 % highest posterior density intervals. The maximum likelihood bootstrap values of 70 and above (left) and the posterior probabilities of 0.95 and above (right) are shown at the nodes
