Hilger, H.

The classification of B. Valdés proposed in Willdenowia 34 in 2004 is shown to be for practical purposes incomplete, incorrect, inconsistent and out of date. A revised list of genera and tribes of Boraginales (Boraginaceae s.l.) occurring in the region based on recent data is presented.
