Abstract
For finite q, we classify the countable, descendant-homogeneous digraphs in which the descendant set of any vertex is a q-valent tree. We also give conditions on a rooted digraph G which allows us to construct a countable descendant-homogeneous digraph in which the descendant set of any vertex is isomorphic to G.
