Majority-rule consensus tree inferred from parsimony analysis of 15 morphological characters for four species of Spathacanthus (tree length = 24 steps, CI = 0.88 and RI = 0.80). Bootstrap values (BS; left) and Jackknife values (JK; right) are shown above branches. Only support values above 50% are shown. Representatives of the genus Odontonema were used as out-group.
