what does Nymphaea and Bupleurum have in common?
Nymphaea Nymphaea is a genus of hardy and tender aquatic plants in the family Nymphaeaceae. The genus has a cosmopolitan distribution. Many species are cultivated as ornamental plants, and many cultivars have been bred. Some taxa occur as introduced species where they are not native, and some are weeds. Plants of the genus are known commonly as water lilies. The genus name is from the Greek νυμφαια, "nymphaia" and the Latin "nymphaea", which mean "water lily" and were inspired by the nymphs of Greek and Latin mythology.
