The chromosome number of Saxifraga gaspensis Fern., a taxon frequently included in the circumpolar species S. nivalis L., or considered a variety, was determined on material from Mount Logan, Gaspé Peninsula, and found to be 2n = 40. As the chromosome number of S. nivalis is 2n = 60 (about 30 data from diverse countries), it seems that the plant described by Fernald in 1917 is specifically different. The authors suggest that S. gaspensis could be a stabilized relictual hybrid between S. nivalis and the closely related diploid species S. tenuis (Wahlenb.) H. Smith, 2n = 20, or a polyploid originating from S. tenuis.
