{{Short description|Order of flowering plants}} [[File:Hamamelis virginiana - Köhler–s Medizinal-Pflanzen-070.jpg|thumb|300px|''Hamamelis virginiana'', a member of the family Hamamelidaceae]] '''Hamamelidales''' is an order of flowering plants formerly accepted in a number of systems of plant taxonomy, including the Cronquist system published in 1968 and 1988. The order is not currently accepted in the Angiosperm Phylogeny Group III system of plant taxonomy, the most widely accepted system as molecular systematic studies have suggested that these families are not closely related to each other.<ref name=APGIII2009>{{Cite journal |last=Angiosperm Phylogeny Group |year=2009 |title=An update of the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG III |journal=Botanical Journal of the Linnean Society |volume=161 |issue=2 |pages=105–121 |doi=10.1111/j.1095-8339.2009.00996.x |doi-access=free |hdl=10654/18083 |hdl-access=free }}</ref><ref name=APGII2003>{{cite journal|doi=10.1046/j.1095-8339.2003.t01-1-00158.x|title=An update of the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG II |journal=Botanical Journal of the Linnean Society |year=2003 |volume=141 |issue=4 |pages=399–436 |doi-access=}}</ref> The APG II system (2003) assigns them to several different orders: Hamamelidaceae and Cercidiphyllaceae to Saxifragales, Eupteleaceae to Ranunculales, Platanaceae to Proteales, and Myrothamnaceae to Gunnerales.<ref name=APGII2003/> Additional studies of the chloroplast genome have since confirmed that the families moved into the Saxifragales are closely related.<ref name=Dong>{{cite journal|last=Dong|first=Wenpan |author2=Chao Xu |author3=Tao Cheng |author4=Kui Lin |author5=Shiliang Zhou|title=Sequencing Angiosperm Plastid Genomes Made Easy: A Complete Set of Universal Primers and a Case Study on the Phylogeny of Saxifragales|journal=Genome Biology and Evolution|year=2013|volume=5|issue=5|pages=989–997|url= |doi=10.1093/gbe/evt063|pmid=23595020 |pmc=3673619 }}</ref>
The Cronquist system (1981) included the order in subclass Hamamelidae with the circumscription:
* order Hamamelidales *: family Hamamelidaceae, now in order Saxifragales *: family Cercidiphyllaceae, now in order Saxifragales *: family Eupteleaceae, now in order Ranunculales *: family Platanaceae, now in order Proteales *: family Myrothamnaceae, now in order Gunnerales<ref name=APGWeb>{{cite web|last=Stevens|first=P.
