A portion (Agrostidinae p.p., Holcinae, Loliinae and Poinae) of the maximum likelihood phylogram inferred from combined plastid data (atpF–atpH, psbK–psbI, psbA–rps19–trnH, matK, trnL–trnF). ML bootstrap support (left) and BI poster probabilities (right) are recorded along branches. No support is shown for branches with bootstrap support <50% and posterior probability <.5. The shaded area of the smaller tree on the left indicates the location in the overall tree of the portion shown. Slashes (//) identify a branch shortened for presentation. An indel in atpF–atpH is mapped onto the phylogram.
