The complexity of type reconstruction for simply-typed lambda calculus with subtype relation resulting from single inheritance (i.e. being a disjoint union of tree-like posets) is analyzed. As a result a class of posets including (but not restricted to) trees is defined, for which the said problem is solvable in polynomial time.
