Maximum-likelihood tree (−Lnlikelihood = 1787.3855, base frequencies A: 0.36600; C: 0.15890; G: 0.17570; T: 0.29940, pinvar = none, shape = 0.8381) inferred from the matK sequences of Elymus L. sensu lato and its affinitive species, under TVM + G model. Numbers with bold above nodes are bootstrap values ≥ 50 %. The capital letters in bracket indicate the genome type of the species. Different color labeled the genera of Elymus L. sensu lato species
