- Dichotomous Key
Phylogenetic investigation based on DNA sequences and morphology has shown the Primulaceae, as traditionally defined, to be polyphyletic (Källersjö et al. 2000). In order that the taxonomic names refect the evolutionary history of this group, some genera (specifically the terrestrial, non-basal-rosette species) have been moved to other families ( Anagallis, Centunculus, Lysimachia, and Trientalis to the Myrsinaceae and Samolus to the Theophrastaceae).
1b. Plants terrestrial; leaf blades simple; peduncles and axes of inflorescence not or scarcely inflated, the flowers in a solitary, terminal umbel or in racemes with whorls of flowers
