An interesting class of C1 foliations

A class of depth two foliations is described in which certain growth conditions allow C1-smoothability, but obstruct higher order smoothability. Similarly, such conditions can obstruct even C1-smoothability. There result uncountably many examples of C1 foliations that are not homeomorphic to C2 foliations, as well as uncountably many C0 foliations that are not homeomorphic to C1 foliations.
