Figure 5. Evolutionary pattern of growth forms in Orchidaceae Acladogram showing the reconstructed ancestral states of growth forms of Orchidaceae. Corresponding taxon names (genera of Apostasioideae and Cypripedioideae, subtribes of Orchidoideae and Epidendroideae, and tribes of Vanilloideae) are shown on the right side of the tree, and the same color scheme of taxon names in Figures 1–4 is used here. Branch colors indicate the reconstructed growth forms as described on the left side of the tree. The green, purple, blue, and orange vertical bars on branches indicate transitions to epiphytism, full mycoheterotrophy, lithophytism, and terrestrial form, respectively. Numbers in four columns between branch tips and taxon names indicate the times of transitions within the taxon group as indicated at the top: between terrestrial (T) and epiphytic (E), other types to full mycoheterotrophy (M), and other types to lithophytic (L). Orc: Orchideae; Ner: Nervilieae; Are: Arethuseae; Mal: Malaxideae.
