Fig. 1 — Maximum clade credibility tree for CCN ingroup species. Asterisk on branches are Bayesian posterior probabilities >0.99. Scale on the bottom right is relative time. Subclades are indicated by gray-shaded boxes. Binary traits are indicated for each species on top of the tree. Geographical distribution: green square = BAF, yellow square = other biomes. Pollination syndromes: green triangle = hummingbird, yellow triangle = bee pollinated, and floral orientation: green circle = resupinate, yellow circle = non-resupinate. Principal component values for morphology and climate are enclosed in gray frame, upper panels. Gray and black vertical bars represent PC1 and PC2, respectively
