'''Caryophyllales''' is an [[Order (biology)|order]] of [[flowering plant]]s that includes the [[cactus|cacti]], [[Dianthus caryophyllus|carnation]]s, [[amaranth]]s, [[beet]]s/chard/[[buckwheat]]/[[rhubarb]], [[ice plant]]s, [[tamarisk]]s and most [[carnivorous plant]]s. Many members are [[succulent plant|succulent]], having fleshy [[Plant stem|stems]] or [[Leaf|leaves]].
==Description==
The Caryophyllales includes about 6% of [[dicot]] [[species]].<ref>[http://www.mobot.org/MOBOT/research/APweb/orders/caryophyllalesweb.htm Caryophyllales<!-- Bot generated title -->]</ref> This order is part of the core [[eudicot]]s.<ref> Judd. W., Campbell, C., Kellog, E., Stevens, P. & M. Donoghue. (2008). Plant Systematics: A Phylogenetic Approach, Third Edition. Sinauer Associates, Inc. Sunderland, MA </ref> Currently, the Caryophyllales contains 33 families, 692 genera and 11,155 species. <ref> Stephens, P.F. (2001). [[Angiosperm Phylogeny Website]]. Version 8, June 2007.http://www.mobot.org/MOBOT/Research/APweb/ </ref>
The monophyly of the Caryophyllales has been supported by [[DNA sequences]], cytochrome c sequence data and heritable characters such as anther wall development and vessel-elements with simple perforations. <ref name="multiple"> Juan et al. (2007). Electrophoretic characterization of ''Amaranthus'' L. seed proteins and its systematic implication. Botanical Journal of the Linnean Society 155: 57-63. </ref>
==Circumscription==
As with all [[taxon|taxa]], the circumscription of the Caryophyllales has changed within various classification systems. All systems recognize a core of families with centrospermous ovules and seeds. More recent treatments have expanded the Caryophyllales to include most [[carnivorous plant]]s.
Although the monophyly of the order has been strongly supported, their placement is still uncertain. Systematists are undecided on whether Caryophyllales should be placed within the rosid complex or sister to the asterid [[clade]]. <ref name = "multiple"/> Caryophyllales is separated into 2 sub-orders: Caryophyllineae and Polygonineae. <ref name = "multiple"/> These two sub-orders were formerly (and sometimes still are) recognized as two orders, the [[Polygonales]] and Caryophyllales. <ref name = "multiple"/>
===APG II===
As circumscribed by the [[APG II system]] (2003), this order includes well-known plants like [[cactus|cacti]], [[Dianthus|carnation]]s, [[spinach]], [[beet]], [[rhubarb]], [[sundew]]s, [[venus fly trap]]s, and [[bougainvillea]]. Recent molecular and biochemical evidence has resolved additional well-supported [[Cladistics|clades]] within the Caryophyllales.

===Cronquist===
[[Image:Melganzenvoet bloeiwijze Chenopodium album.jpg|thumb| ''Chenopodium album'']]
The [[Cronquist system]] (1981) also recognised the order, with this circumscription:
* order Caryophyllales
*: family Achatocarpaceae
*: family Aizoaceae
*: family Amaranthaceae
*: family Basellaceae
*: family Cactaceae
*: family Caryophyllaceae
*: family Chenopodiaceae
*: family Didiereaceae
*: family Nyctaginaceae
*: family Phytolaccaceae
*: family Portulacaceae
*: family Molluginaceae
The difference with the order as recognized by APG lies in the first place in the concept of "order". The APG favours much larger orders and families, and the order Caryophyllales sensu APG should rather be compared to subclass [[Caryophyllidae]] sensu Cronquist.
A part of the difference lies with what families are recognized. The plants in the Stegnospermataceae and Barbeuiaceae were included in Cronquist's Phytolaccaceae. The Chenopodiaceae (still recognized by Cronquist) are included in Amaranthaceae by APG.
New to the order (sensu APG) are the Asteropeiaceae and Physenaceae, each containing a single genus, and two genera from Cronquist's order [[Nepenthales]].
===Earlier circumscriptions===
Earlier systems, such as the [[Wettstein system]], last edition in 1935, and the [[Engler system]], updated in 1964, had a similar order under the name [[Centrospermae]].
