After decades of progress in understanding the phylogeny of </span><span lang="en-GB"><em>Asteridae</em></span><span lang="en-GB"> and </span><span lang="en-GB"><em>Campanulidae</em></span><span lang="en-GB">, the three clades here associated with those three names are better supported than ever, and the phylogenetic definitions presented here therefore differ little from the pre-</span><span lang="en-GB"><em>PhyloCode</em></span><span lang="en-GB"> phylogenetic definitions provided 25 years ago by Donoghue </span><span lang="en-GB"><em>et al.</em></span><span lang="en-GB"> (2001). It is abundantly clear that </span><span lang="en-GB"><em>Dipsacales</em></span><span lang="en-GB"> is a clade composed of two very well-supported and easily identified sister clades—here </span><span lang="en-GB"><em>Adoxaceae</em></span><span lang="en-GB"> and </span><span lang="en-GB"><em>Caprifoliaceae</em></span><span lang="en-GB">—that were not recognized in pre-phylogenetic angiosperm classification systems. The impetus for solidifying these names now under the </span><span lang="en-GB"><em>PhyloCode</em></span><span lang="en-GB"> is that decisions made in the past decade by the Nomenclatural Committee for Vascular Plants of the </span><span lang="en-GB"><em>International Code of Nomenclature for algae, fungi, and plants</em></span><span lang="en-GB"> (</span><span lang="en-GB"><em>ICN</em></span><span lang="en-GB">) have led to the mandatory replacement of the name </span><span lang="en-GB"><em>Adoxaceae</em></span><span lang="en-GB"> by </span><span lang="en-GB"><em>Viburnaceae</em></span><span lang="en-GB"> for a family that includes </span><span lang="en-GB"><em>Viburnum</em></span><span lang="en-GB">, </span><span lang="en-GB"><em>Sambucus</em></span><span lang="en-GB">, and </span><span lang="en-GB"><em>Adoxa</em></span><span lang="en-GB">. This unfortunate decision to replace a widely accepted name, used many thousands of times in the literature, by a name that has rarely been used, can now be circumvented (by those who wish to do so) by correctly observing that </span><span lang="en-GB"><em>Adoxaceae</em></span><span lang="en-GB"> is the accepted name for this clade under the </span><span lang="en-GB"><em>PhyloCode</em></span><span lang="en-GB">. This paper prepares the way for a comprehensive phylogenetic classification and nomenclature of both </span><span lang="en-GB"><em>Adoxaceae</em></span><span lang="en-GB"> and </span><span lang="en-GB"><em>Caprifoliaceae</em></span><span lang="en-GB">. </span></span></span></span></p> <p> </p> Michael J.
