Maximum-likelihood tree (−Lnlikelihood = 1174.7281, base frequencies A: 0.35970; C: 0.17790; G: 0.18010; T: 0.28230, pinvar = none, shape = 0.1481) inferred from the trnH-psbA sequences of Elymus L. sensu lato and its affinitive species, under K81uf + 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
