  We show how several results about p-adic lattices generalize easily to
lattices over valuation ring of arbitrary rank having only the Henselian
property for quadratic polynomial. If 2 is invertible we obtain the uniqueness
of the Jordan decomposition and the Witt Cancelation Theorem. We show that the
isomorphism classes of indecomposable rank 2 lattices over such a ring in which
2 is not invertible are characterized by two invariants, provided that the
lattices contain a primitive norm divisible by 2 of maximal valuation.
