Overview of Angiosperm clades

This tree is the one redrawn from Fig. 1 in Qiu et al. (1999; click HERE to see other trees). These authors analyzed sequence data combined from five genes: mitochondrial atp1 and matR, chloroplast atpB and rbcL, and nuclear 18S rDNA. This paper also identified the New Caledonian monotypic genus Amborella (Magnoliales: Amborellaceae) as the most primitive living angiosperm. Because the 103 genera sampled in this analysis included eight gymnosperms, these results also demonstrate how the Gnetales are apparently not closely related to the earliest angiosperms.
