In an analysis of three genes and morphology (Doyle & Endress, 2000), which did not include Ceratophyllum, Chloranthaceae were sister to all other mesangiosperms, based in part on their retention of ascidiate carpels like those of the ANITA lines.
Even completely ascidiate carpels are monosymmetric (e.g., basalmost angiosperms; Endress, 1986b, 2005; or Araceae; Igersheim et al., 2001).
Carpels of Brasenia (Cabombaceae) are completely ascidiate despite a long stigmatic crest.
