Divergence times and standard errors (in Mya) for deep-level angiosperm nodes as estimated by PL analyses
| Node | Unconstrained | Stem eud, 125 Mya | Crown eud, 125 Mya |
|---|---|---|---|
| Angiosperms | 169.6 (3.79) | 169.7 (3.46) | 169.8 (3.46) |
| Nymph + Ill + mesangiosperms | 163.3 (2.68) | 163.5 (2.63) | 163.5 (2.63) |
| Illicium + mesangiosperms | 154.7 (2.47) | 154.8 (2.53) | 154.9 (2.53) |
| Mesangiosperms | 143.8 (2.45) | 143.9 (2.67) | 144.0 (2.66) |
| Chloranthus + magnoliids | 140.3 (2.43) | 140.4 (2.54) | 140.5 (2.54) |
| Magnoliids | 130.1 (2.24) | 130.3 (2.20) | 130.3 (2.20) |
| Cerato + eud + mono | 143.1 (2.99) | 143.1 (3.18) | 143.0 (2.97) |
| Monocots | 128.9 (2.50) | 129.2 (2.69) | 129.1 (2.69) |
| Cerato + eud | 141.3 (2.72) | 141.4 (2.97) | 141.4 (3.18) |
| Eudicots | 124.8 (3.2) | 124.9 (3.43) | 125.0 (3.43) |
The first column gives results of the unconstrained analysis; the second and third columns give results when the minimum age of stem group or crown group eudicots is constrained to be 125 Mya. Standard errors are given in parentheses. Cerato, Ceratophyllum; eud, eudicots; mono, monocots; Ill, Illicium; Nymph, Nymphaeales.
