Editing Myrtales (section)

==Taxonomy==
Myrtales include the following nine families, according to the [[APG III system]] of [[Taxonomy|classification]]:<ref name="apgiii">{{Citation |last=Angiosperm Phylogeny Group |year=2009 |title=An update of the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG&nbsp;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>
* [[Alzateaceae]]
* [[Combretaceae]] ([[Combretum imberbe|leadwood]] family)
* [[Crypteroniaceae]]
* [[Lythraceae]] ([[Lythrum|loosestrife]] and [[pomegranate]] family)

* [[Onagraceae]] ([[evening primrose]] and [[Fuchsia]] family)
* [[Penaeaceae]] (including [[Oliniaceae]], [[Rhynchocalycaceae]])
* [[Vochysiaceae]]

The APG III system places the order within the [[Rosids|eurosids]]; this is corroborated by the placement of the Myrtales in the Malvid clade by the ''One Thousand Plant Transcriptomes'' Initiative.<ref>{{cite journal | vauthors = Leebens-Mack JH, Barker MS, Carpenter EJ, Deyholos MK, Gitzendanner MA, Graham SW, etal | collaboration = One Thousand Plant Transcriptomes Initiative | title = One thousand plant transcriptomes and the phylogenomics of green plants | journal = Nature | volume = 574 | issue = 7780 | pages = 679–685 | date = October 2019 | pmid = 31645766 | pmc = 6872490 | doi = 10.1038/s41586-019-1693-2}}</ref> 

Myrtales are placed as a sister to the [[eurosids II]] [[clade]] as of the publishing of the ''Eucalyptus grandis'' genome in June 2014.<ref name=Myburg>{{cite journal | vauthors = Myburg AA, Grattapaglia D, Tuskan GA, Hellsten U, Hayes RD, Grimwood J, Jenkins J, Lindquist E, Tice H, Bauer D, Goodstein DM, Dubchak I, Poliakov A, Mizrachi E, Kullan AR, Hussey SG, Pinard D, van der Merwe K, Singh P, van Jaarsveld I, Silva-Junior OB, Togawa RC, Pappas MR, Faria DA, Sansaloni CP, Petroli CD, Yang X, Ranjan P, Tschaplinski TJ, Ye CY, Li T, Sterck L, Vanneste K, Murat F, Soler M, Clemente HS, Saidi N, Cassan-Wang H, Dunand C, Hefer CA, Bornberg-Bauer E, Kersting AR, Vining K, Amarasinghe V, Ranik M, Naithani S, Elser J, Boyd AE, Liston A, Spatafora JW, Dharmwardhana P, Raja R, Sullivan C, Romanel E, Alves-Ferreira M, Külheim C, Foley W, Carocha V, Paiva J, Kudrna D, Brommonschenkel SH, Pasquali G, Byrne M, Rigault P, Tibbits J, Spokevicius A, Jones RC, Steane DA, Vaillancourt RE, Potts BM, Joubert F, Barry K, Pappas GJ, Strauss SH, Jaiswal P, Grima-Pettenati J, Salse J, Van de Peer Y, Rokhsar DS, Schmutz J | display-authors = 6 | title = The genome of Eucalyptus grandis | journal = Nature | volume = 510 | issue = 7505 | pages = 356–62 | date = June 2014 | pmid = 24919147 | doi = 10.1038/nature13308 | url = https://biblio.ugent.be/publication/5655667/file/5655749.pdf | bibcode = 2014Natur.510..356M | s2cid = 4392576 | doi-access = free }}</ref>

The [[Cronquist system]] gives essentially the same composition, except the [[Vochysiaceae]] are removed to the order [[Polygalales]], and the [[Thymelaeaceae]] are included. The families [[Sonneratiaceae]], [[Trapaceae]], and [[Punicaceae]] are removed from the Lythraceae. In the classification system of [[Rolf Dahlgren|Dahlgren]] the Myrtales were in the [[superorder]] Myrtiflorae (also called Myrtanae). The APG{{nbsp}}III system agrees with the older Cronquist circumscriptions of treating Psiloxylaceae and Heteropyxidaceae within Myrtaceae, and Memecyclaceae within Melastomataceae.

[[Ellagitannin]]s are reported in dicotyledoneous angiosperms, and notably in species in the order Myrtales.<ref>{{cite journal | vauthors = Yoshida T, Amakura Y, Yoshimura M | title = Structural features and biological properties of ellagitannins in some plant families of the order Myrtales | journal = International Journal of Molecular Sciences | volume = 11 | issue = 1 | pages = 79–106 | date = January 2010 | pmid = 20162003 | pmc = 2820991 | doi = 10.3390/ijms11010079 | doi-access = free }}</ref>
