| Notes | The majority of chromosome counts indicate a functional base number of x = 20-21. Most species then are diploids and tetraploids. Two species with 2n = 30 and 32 (Juncus tenuis, J. trifidus) may indicate x = 15 og 16 as additional base numbers. |
| Chromosomes | 106-108 100-ca. 120. - Europe, Russia, Canada, U.S.A. - Numerous reports. Löve and Löve (1975a) accepted three reports of 2n = 106, one from an arctic locality, and omitted the numerous other reports (including their own) within the wider range reported above. |
