FIGURES 2–5. Pectinate cladogram and unordered correlations. 2, pectinate tree, optimized for characters 0 and 1; 3, correlation of characters 0 (x) and 1 (y) on pectinate tree ("·": observed state combination; 0: zero extra steps needed; 1: one extra step needed); 4, pectinate tree with optimization for characters 2 and 3, showing ambiguity; 5, correlation of characters 2 (x) and 3 (y) on pectinate tree.
