Measurements were log-transformed prior to analysis. Significant differences against J. darcyana (ancestral rotate) indicated by * (* p < 0.05; ** p < 0.001; *** p < 0.0001); significant differences between J. calliantha and J. dendroidea (convergent campanulate) indicated by ^ (^ p < 0.05; ^^ p < 0.001; ^^^ p < 0.0001). ND, not determined, as sample sizes were too small
