In the BEAST analysis, the age was estimated with the
tree priors set as follows: i) age for the Goodyerinae (a monophyletic
subtribe) as uniform distribution with a lower bound of
15 Mya and an upper bound of 120 Mya; ii) age for both
Dendrobium and Earina as uniform distribution (lower bound:
20 Mya; upper bound: 120 Mya); iii) age for the root of the tree
with a normal prior distribution as 106.568.21 Mya (95% CI: 93–
120 Mya) [42].
