Primulaceae
Phylogeny

Primulaceae s.l. sensu APG III form part of the speciose (species rich) Asterid order Ericales s.l., with about 12,000 species and 22 families as per APG IV. Ericales is one of four major clades within the asterids, where it is sister to the euasterids. The phylogenetic structure of Ericales, as shown in the following cladogram, consists of seven major suprafamilial clades (e.g. balsaminoids, styracoids) and a group of "core" Ericales. Within the eracalean families, Primulaceae s.l. is shown as a sister group to Ebenaceae, and both are sister to Sapotaceae. These three families make up the primuloid clade.
