Description
Vegetative characteristics
Nymphaea potamophila is an aquatic herb. The elliptic-sagittate, papery leaf blades of floating leaves are up to 20 cm long and 10 cm wide.[4] The leaf margin is entire and flat.[5] The adaxial surface is coloured in green with overlaying patterns of red variegation. The abaxial surface has a greenish base colour accompanied by dark red variegation, but also exhibits patterns of branched, rusty-brown striations.[4] The leaf structure is compact and the leaves are very thin (145.50 μm). This gives the leaves cold tolerance.[6] The glabrous, 3 mm wide petioles are very long and can exceed 4 m in length.[4]
Generative characteristics
The nocturnal floating flowers are connected to glabrous, 4 mm wide peduncles, which can exceed 4 m in length.[4][7]
