In many arctic-alpine plant groups, reticulate* evolutionary histories have resulted in problems with species delimitation and phylogenetic reconstruction. In the Saxifraga rivularis complex, the number of species accepted ranges from a single polymorphic one to several. The preceding statement is paraphrased from the introduction to the article: Taxonomy and Evolutionary Relationships in the Saxifraga rivularis Complex, published in Systematic Botany, Volume 31, Issue 4 (October 2006)

* An intertwining network evolution, where evolutionary changes are passed on by a random network resulting in numerous differences between isolated populations.
