Chloranthaceae are one of five clades making up mesangiospenns, along with eudicots, magnoliids (in a restricted monophyletic sense, including Magnoliales, Laurales, Canellales, and Piperales), monocots, and the rootless aquatic genus Ceratophyllum. Since most ANITA groups (except the highly reduced Hydatellaceae in Nymphaeales: Saarela et al., 2007) have multi-parted flowers, it is most parsimonious to assume that the flowers of Chloranthaceae are reduced rather than primitively simple (Endress & Doyle, 2009; Doyle & Endress, 2011).
