This paper is concerned with the question whether the lattice sum (join) V $ V' of two finitely based lattice varieties V and V' is finitely based. An example is constructed showing that this is not always the case. On the other hand, it is proved that if V C M and (V')\* = (N)', then V + V' is fin
