BEAST xml - reduced taxa, rate-based

<p>BEAST xml for dating aquatic lineages of Oxalis. In this analysis, the reduced data set, removing taxa with missing data for one partition, is analysed using a rate-based approach, allowing the mean rates to vary across both partitions. The calibration used a uniform prior on both mean rates, with minimum value 0 and maximum value 0.0029 s/s/my.
