stemma established for a closed recension does not have any crossing branches in its highest projections (though the contrary – i.e. that a stemma without crossing branches necessarily corresponds to a closed recension – does not hold):


Fig. 1. A closed recension. In this stemma, any manuscript (or, in square brackets, hyparchetype) is the copy of only one exemplar. From West (1973, 32).

On the other hand, a contaminated tradition is a paradigmatic example of an open recension. The stemma representing that tradition will have crossing or converging branches, either solid (often to indicate a high degree of influence) or dotted (often to indicate a lower degree of influence).

Martin West (1973) discusses in some detail how one should distinguish between closed and open recensions, and how to deal with them. For the closed recension, see pp. 31–37, and for the open recension, pp. 37–47.


Fig. 2. An open recension. In this stemma, several manuscripts are the copies of more than one exemplar. From West (1973, 40).
