Abstract
In the mass region up to M < 2400 MeV we systematise mesons on the plots (n,M2) and (J,M2), thus setting their classification in terms of n2S+1LJ q anti-q states. The trajectories on the (n,M2)-plots are drawn for the following (IJPC)-states: a0(10++), a1(11++), a2(12++), a3(13++), a4(14++), pi(10-+), pi2(12-+), eta(00-+), eta2(02-+)$, rho(11--), f0(00++), f2(02++). All trajectories are linear, with nearly the same slopes. At the (J,M2)-plot we set out meson states for leading and daughter trajectories: for pi, rho, a1, a2 and P'.
