7101 Primula L.
Notes: Trift et al. (2002), based on cpDNA sequences, found Primula as traditionally circumscribed to be paraphyletic and found that several other genera should be included, among these Dodecatheon and Cortusa. Dodecatheon connects to Primula sect. Auriculastrum and Cortusa to Primula sect. Auganthus (with, e.g., P. cortusoides). This view have found support in some subsequent studies (see Cholewa and Kelso 2009). As this cluster also contains some very deviant genera like Soldanella and even Hottonia, it may be more appropriate to transfer some sections of Primula to other genera (or to wait for more genes to be analysed). The arctic representatives of Primula belong within the main, monophyletic core of the genus and will not be involved in the possible turbulence.
The majority of the arctic species belong to sect. and subsect. Aleuritia. A recent study by Guggisberg et al. (2006) elucidated the relationships among these species and vs. sect. Armerina and is commented on below.
