Boraginaceae have erroneously been associated with helicoid cymes, when upon closer inspection they exclusively possess scorpioid cymes (cincinni). A discussion of the inflorescence structure in Boraginaceae is presented with the help of an over-view of monochasial branching systems and a three-dimensional representation thereof Reasons for the incorrect description of Boraginaceae inflorescences are also provided

Plastid (trnL(UAA) intron, trnL(UAA)-trnF(GAA) spacer) and nuclear (ITS1) DNA sequence analyses do not only confirm the separate position of \„Echium maculatum L.\" which this species holds within the genus Echium due to the presence of a bicapitate rather than a bifid stigma, but necessitate the exclusion of the taxon from the genus Echium (Boraginaceae) and the description of a new genus, Pontechium.

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.
