Portulacales
Synonym: Portulacaceous alliance; Portulacinae; Portulacaceous cohort.
Clades: Caryophyllidae, Asteranae, Angiospermae, Plants.BotanyHerbs; many succulents.TaxonomyPortulacales is a clade in the Apg4 classification, a Suborder in the Order Caryophyllales. It is called the Potulacoid clade. It contains the Families: Anacampserotaceae, Basellaceae Cactaceae, Didieraceae, Halophytaceae, Montiaceae, Portulacaceae and Talinaceae. Cactaceae is by far the biggest family in Portulacales. In good right the Order could be called Cactales. Recently there have been made big shift in some families. The quite big family Portulacaceae lost most of its members to Montiaceae and has only Portulaca as its member.Plant theoryIn the Plant theory Portulacales is an Order in the Subclass of Caryophyllidae and is placed in Phase 1. The placement in Sub- phases is tentative. In the update of the Plant theory The Portulalcales is reordered. Some small families have been fused.
In Subphase 1 is combined Didieraceae and Halophytaceae.
In Subphase 2 is combined Portulacaceae, Anacampserotaceae, Talinaceae and Basellaceae.
In Subphase 3 is Montiaceae.
The Cactaceae is split in its 4 Subfamilies: Echinocactoideae, Phyllocactoideae, Opuntioideae and Cereoioideae respectively in Subphase 4 to 7.Subphases1. Halophytaceae, Didiereacaeae

2. Portulacaceae, including Anacampserotaceae, Basellaceae, Talinaceae, Didiereaceae: they feel alone in relationships, adapt too much to the other.
3. Montiaceae: they stay single, in triangular relationships.
4. Echoinocactoideae: they prefer to stay single as others are imperfect.
5. Phyllocactoideae.
6. Opuntioideae: they prefer to stay single from fear of being used.
7. Cereoideae.LiteratureNyffeler, Reto & Eggli, Urs; A farewell to dated ideas and concepts – molecular phylogenetics and a revised suprageneric classification of the family Cactaceae; Zurich Open Repository and Archive; 2010.
