Abstract
We have studied the evolution of galaxian morphologies from ground-based, g ood-seeing images of 9 clusters at z=0.09-0.25. The comparison of our data with those relative to higher redshift clusters (Dressler et al., 1997, D97 ) allowed us to trace for the first time the evolution of the morphological mix at a look-back time of 2-4 Gyr, finding a dependence of the observed e volutionary trends on the cluster properties.
