Everything about Potamogetonaceae totally explained
Potamogetonaceae is a family of
monocotyledonous
flowering plants in the order
Alismatales, with a
cosmopolitan distribution.
The
APG system (1998) and
APG II system (2003) places it in the clade
monocots. Their concept of the family includes the plants sometimes treated as family
Zannichelliaceae, but to exclude the genus
Ruppia. So circumscribed, the family consists of seven genera (notably
Potamogeton), totalling about 90 species of perennial
aquatic plants. Their
leaf blades can be either floating or submersed, and their stems are often joined. The
flowers are tetramerous: the floral formula (sepals; petals; stamens; carpels) is [4;0;4;4]. The plants have no petals. The
fruit consists of 1-4
drupelets or
achenes.
