Cladistics is concerned with entire branchings by grouping all the common  descendants into a clade as a related group and no others.this is a narrower definition of an older, less precise concept.  cladistics is a way of grouping the related branches based on sharing derived characters within the group. however these characters are not found in other species except by convergence.
phylogeny is a way of tracking evolutionary relationships based on shared characters  based on artificially defined levels of taxonomy. this method allows convergent characters to be grouped despite their having followed a separate evolutionary path. taxonomy is the rank levels while phylogeny is the path through the ranks.
