Subfamily: Mesembryanthemoideae (mesems in part)

Life > eukaryotes > Archaeoplastida > Chloroplastida > Charophyta > Streptophytina > Plantae (land plants) > Tracheophyta (vascular plants) > Euphyllophyta > Lignophyta (woody plants) > Spermatophyta (seed plants) > Angiospermae (flowering plants) > Eudicotyledons > Core Eudicots > Order: Caryophyllales > Family: Aizoaceae

The subfamilies Mesembryanthemoideae and Ruschioideae make up the group of succulents loosely termed the mesems that in some classifications are placed in a separate family, the Mesembryanthemaceae. In this classification they are placed in the Aizoaceae because evidence suggests that mesems were derived from within this group (see under Aizoaceae for more information).
