    "abstract": "Two families of quasi exactly solvable 2*2 matrix Schroedinger operators are\nconstructed. The first one is based on a polynomial matrix potential and\ndepends on three parameters. The second is a one-parameter generalisation of\nthe scalar Lame equation. The relationship between these operators and QES\nHamiltonians already considered in the literature is pointed out.",
