Hugoniaceae, Humiriaceae and Ixonanthaceae are small families, that we do not have homeopathic information of. In the Apg3 classification Hugoniaceae is included in Linaceae and the other two Families are standing on their own in the Order Malpighiales, not having clear links. Tentatively these families are included in Linaceae in the Plant theory.
