Potamogetonaceae | |
Publ. & Syn. | Zannichelliaceae. |
Notes | We follow Stevens (2001 onwards) and include Zannichelliaceae in Potamogetonaceae. Elven and Tzvelev: Several arguments have been brought forward for recognition of Potamogeton subg. Coleogeton as a genus apart from Potamogeton, first as Coleogeton (Les and Haynes 1996) but due to priority as Stuckenia (Holub 1997; Tzvelev 2000a; Haynes and Hellquist 2000c). See the numerous differential characters reported by Preston (1995, as subg. Coleogeton). We accept Stuckenia. |
Chromosomes | 12 (2x). - Europe, Canada (W), Greenland. - Numerous reports. The majority of chromosome number reports from the northernmost regions may belong to Z. angustifolia. Not included: A report of 2n = 24 (4x) from New Zealand may belong to another species. |
