Portulacineae is a suborder of flowering plants in the order Caryophyllales comprising the families Anacampserotaceae, Basellaceae, Cactaceae (cacti), Didiereaceae, Halophytaceae, Montiaceae, Portulacaceae, and Talinaceae. All three major kinds of succulent plant — stem succulents, leaf succulents, and caudiciform plants — are represented within this suborder. Formerly, there were only four families: Basellaceae, Cactaceae, Didiereaceae, and Portulacaceae.
