Abstract: A continuum $ M$ is said to be $ \lambda $ connected if every two points of $ M$ can be joined by a hereditarily decomposable subcontinuum of $ M$. Here we prove that a bounded plane continuum that does not have infinitely many complementary domains is $ \lambda $ connected if and only if its boundary does not contain an indecomposable continuum. It follows that every $ \lambda $ connected bounded nonseparating subcontinuum of the plane has the fixed point property.
