The stable and unstable
manifolds of an Anosov diffeomorphism are not leaves of C1-foliation. Instead, their
unions comprise two laminations; that is, two C0-foliations which have C1-smooth
leaves and continuous nonsingular tangent plane fields. Recently C. Ennis has shown
that laminations have transversals at every point. In this note, the existence of
transversals is shown to require plane field continuity.
