(1) 10 (2x, x = 5). - Europe (Iceland), Canada (Hudson Bay). - D. Löve (1953); Löve and Löve (1956b, 1982b).
(2) 16 (2x, x = 8). - Europe (Iceland), Asia (E). - Löve and Löve (1986a); Yuan and Küpfer (1993).
This is another problem with divergent chromosomal information due to the Löves. In 1975 they reported the base number to be x = 5 based on two counts on Icelandic plants in the 1950s. Later reports rather indicate a base number of x = 8. There are surprisingly few reports for this widespread species and four of the five known to us are due to the Löves. The number reported from the related Lomatogonium carinthiacum supports x = 8 as the base number. We are tempted to reject the 2n = 10 reports altogether. This number is only known from one other northern representative of Gentianaceae, Comastoma tenellum, and misidentification of these two species is not very likely.
