Hypotheses on the origin of the current distribution patterns and bicontinental disjunctions of Cordiaceae, Ehretiaceae, and Heliotropiaceae (Primarily Woody Boraginales) are tested by pairwise comparison of Kimura two-parameter distances. Estimated absolute dates of fossils and geological events (plate tectonics, climate changes) were used to calibrate a molecular clock. A mid-Cretaceous origin of the Primarily Woody Boraginales is proposed with an initial diversification in South America. Plate tectonics appear to play a minor role in their phylogeography. Most disjunctions are best explained by the rare events of long-distance dispersal because of the widespread occurrence of drupaceous fruits and their potential for endozoochoria. Furthermore, migrations and extinctions might have played a considerable role in the formation of the current distribution patterns.

The systematic position of Argentinean Cortesia cuneifolia (Ehretiaceae, Boraginales) is investigated based both on morphological and on ITS1 sequence data. Inferred from a molecular phylogeny, monotypic Cortesia is not isolated from other taxa of Ehretiaceae as previously suggested, but is nested within Ehretia. Cortesia shares a two-parted endocarp with the Ehretia II subclade (including Ehretia microphylla ), which is considered as a derived condition within Ehretiaceae and is the most striking indication for a close relationship of the two. ITS1 sequence data and specialised leaf morphology suggest that Ehretia microphylla is probably the sister species of Cortesia cuneifolia, for which a new name is proposed: Ehretia cortesia.
