 | | Previous studies on the morphology, anatomy, and palynology of Laurales have failed to satisfactorily resolve family relationships. |
 | | Sequences from three regions of the plastid genome, the rbcL gene, the trnL-trnF intergenic spacer, and the rpl16 intron (comprising 2614 bp and 350 parsimony-informative characters), have been produced for 24 genera, with 5 of the 7 families represented by all their genera, as well as representatives of the related order Magnoliales. |
 | | Spacer and intron sequences of Amborellaceae and Chloranthaceae, which have sometimes been placed in Laurales, can not be aligned with the remaining lauralean and magnolialean sequences. |
