[ˈklædəʊɡræm, also ˈkleɪd-]

From κλάδος ‘branch’(cf. cladistics) and a contracted form of dendrogram ('tree-graph') or diagram, in both cases ultimately from γράμμα 'anything written'.

In cladistics, according to Kitching et al. (1998), a cladogram is "a branching diagram specifying hierarchical relationships among taxa based upon homologies (synapomorphies). A cladogram includes no connotation of ancestry and has no implied time axis" (Kitching et al. 1998, 202). A phylogenetic tree, on the other hand, is "an hypothesis of genealogical relationships among a group of taxa with specific connotations of ancestry and an implied time axis" (Kitching et al. 1998, 213). For an older definition cf. phylogram.
