Figure 15.2–The UPGMA phenogram resulting from isozyme analysis of 36 populations of Arceuthobium. Cophenetic correlation = 0.968, standard deviation 6.6%. Codes following species name indicate population number (table 15.1) and taxonomic affilation according to the classification of Hawksworth and Wiens (table 14.1 compare with table 15.2). Key: A = subgenus Arceuthobium, V = subgenus Vaginata, V = section Vaginata, C = section Campylopoda, M = section Minuta, c = series Campylopoda, r = series Rubra, s = series Stricta.
