The division on C. aquatilis and C. concolor have been made differently in different areas. In Norway and Greenland, C. concolor (as C. aquatilis subsp. stans) has been considered a very northern and high-alpine, low-grown plant. In Russia, the majority of authors (e.g., Kuzeneva 1954; Egorova 1966a; Malyschev 1990) have applied a wider concept of it, including many more southern plants. This was confirmed by field investigations in northern Siberia in 2004 and Chukotka in 2005 where we mainly found what we would consider C. aquatilis in the European meaning in regions where the Russians mainly had reported the plants as subsp. stans. The North American concept of C. aquatilis var. minor (i.e., C. concolor) as applied by Standley et al. (2002) also seems to be much wider than the Greenland and European one. After survey of some northern European material, we now think that Russians and North Americans may have included too much material in C. concolor. We also found, to our surprise, that the majority of specimens (hundreds) that we now would assign to C. concolor from the Scandinavian mountains previously had been assigned to the hybrid C. aquatilis x bigelowii, in spite of their fertility and of these two proposed parental species rarely growing close together.
The results of Dragon and Barrinton (2009) support a major taxon besides C. aquatilis and C. sitchensis, including both the northern var. minor (subsp. stans) and the eastern North American var. substricta Kük. As for taxonomic revision, Dragon and Barrington preferred to make "no change, pending broader sampling" as concerned C. aquatilis.
