From: An ancient tropical origin, dispersals via land bridges and Miocene diversification explain the subcosmopolitan disjunctions of the liverwort genus Lejeunea

Figure 1

Time-calibrated tree and global diversification pattern of Lejeunea. The chronogram tree indicates mean ages and node bars show the 95% credibility intervals. Red star indicates fossil calibration. Scanning electron micrographs show representatives of Lejeunea; from top: Lejeunea stephaniana, L. mimula in ventral view, and L. kinabalensis, L. umbilicata in dorsal view. Paleoenvironment-dependent diversification processes in Lejeunea, indicating a weak positive correlation between temperatures and speciation rates. Nodes 1–8 are summarized in Table 1. (Plio., Pliocene).
