Maximum-likelihood tree (−Lnlikelihood = 2553.6868, base frequencies A: 0.2286, C: 0.2966, G: 0.2794, T: 0.1954, pinvar = none, shape = 0.4121) inferred from the nrITS sequences of Elytrigia sensu lato and its affinitive species, under GTR+ G model. Numbers above and below branches indicate posterior probabilities (PP) ≥ 70% by BI analysis and bootstrap support (BS) ≥ 50% by ML, respectively
