(sometimes including Chenopodiaceae
), Cactaceae, and Portulaceae. This roughly constitutes the Caryophyllales as defined before the Angiosperm Phylogeny Group
expanded it to include the plants which can be classified in the Polygonales
or Polygonineae (depending on whether they are considered an order or a suborder of Caryophyllales). The Caryophyllineae is sometimes called "core Caryophyllales" and the Polygonineae is sometimes called the "non-core Caryophyllales".
The core Caryophyllineae sub-order is well-supported with numerous distinctive synapomorphies, such as: 1) sieve tubes of phloem with plastids with peripheral ring of proteinaceous filaments (often with a central protein crystal), 2) presence of betalains, 3) loss of the rpl2 intron in cpDNA, 4) single whorl of tepals, 5) pollen with spinulose and tubiliferous/punctuate exine, 6) placentation free-central to basal, curved embryo
, and 7) presence of perisperm with endosperm scanty or lacking
Systematics
Caryophyllales is separated into 2 sub-orders: Caryophyllineae and Polygonineae. Caryophyllineae contains 21 families and 8,600 species and major families include AizoaceaeAizoaceae
The Family Aizoaceae or Ficoidaceae is a taxon of dicotyledonous flowering plants containing 135 genera and about 1900 species. They are commonly known as stone plants or carpet weeds. Species that resemble stones or pebbles are sometimes called mesembs...

Chenopodiaceae were a family of flowering plants, also called the Goosefoot Family. They are now included within family Amaranthaceae. The vast majority of Chenopods are weeds, and many are salt and drought tolerant. A few food crops also belong to the family: spinach, beets, chard, quinoa, and...
