Chronograms for the Resseliella midges (top) and the Kadsura species they pollinate (bottom), with 95 % error ranges for the time estimates of nodes discussed in the text. See the Materials and Methods for fossil and rate calibrations, and Figs S6 and S8 for errors around time estimates on nodes with >96 % posterior probability. A phylogeny with multiple midge samples per Kadsura species is shown as Fig. S7.
