  This paper is devoted to the study of codimension two holomorphic foliations
and distributions. We prove the stability of complete intersection of
codimension two distributions and foliations in the local case. Converserly we
show the existence of codimension two foliations which are not contained in any
codimension one foliation. We study problems related to the singular locus and
we classify homogeneous foliations of small degree.
