We introduce a Hopf algebra of planar decorated rooted trees H D P ,R which is non commutative and non cocommutative and generalizes the Hopf algebra of rooted trees H D R of Connes and Kreimer. We show that H D P ,R satisfies a universal property in Hochschild cohomology and deduce that it is self-

We relate the algebra of planar rooted trees introduced in the first part [6] to several algebras of trees: the Brouder-Frabetti algebra of binary trees, the deformations of Moerdijk and van der Laan, the free dendriform algebra of Loday and Ronco, and the Grossman-Larson algebra. We construct a sub
