Fig. 1 in Phylogenetic relationships and time-calibration of the South American fossil and extant species of southern beeches (Nothofagus)

Fig. 1. Strict consensus tree from Implied Weight Analysis (IWA) (k = 8). Dashed cladogram branches indicate fossil taxa. Consistency Index (CI): 0.51; Retention Index (RI): 0.78. Shaded circles (a–c) indicate the three possible placements of the two taxa Nothofagus alpina and Nothofagus elongata before pruning as indicated by IterPCR. Green/brown and black leaves are representatives of living and fossil species, respectively. Abbreviations: NCA, New Caledonia; NGU, New Guinea; NZE, New Zealand; SAU, Southern Australia; SSA, Southern South America; TAS, Tasmania.
