Historical biogeography of Boraginales: West Gondwanan vicariance followed by long‐distance dispersal?

Aim To examine the historical biogeography of the Boraginales using molecular dating and ancestral area reconstruction. Location World‐wide. Methods We constructed data sets that included all major clades of Boraginales and all orders of asterids using previously published sequences of four plastid markers ( trn L ‐trn F, rps 16, ndh F, rbc L). We estimated divergence times using a Bayesian uncorrelated, lognormal relaxed clock approach with...
