Panarctic Flora


24 Potamogetonaceae


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.
