Are Actaea and Nymphoides both aquatic plants?
Nymphoides Nymphoides, or floatingheart, is a genus of aquatic flowering plants in the family Menyanthaceae. The genus name refers to their resemblance to the water lily "Nymphaea". "Nymphoides" are aquatic plants with submerged roots and floating leaves that hold the small flowers above the water surface. Flowers are sympetalous, most often divided into five lobes (petals). The petals are either yellow or white, and may be adorned with lateral wings or covered in small hairs. The inflorescence consists of either an umbellate cluster of flowers or a lax raceme, with internodes occurring between generally paired flowers.
Aganippe (naiad) Aganippe ( ; Ancient Greek: Ἀγανίππη ) was the name of both a spring and the Naiad (a Crinaea) associated with it. The spring is in Boeotia, near Thespiae, at the base of Mount Helicon, and was associated with the Muses who were sometimes called Aganippides. Drinking from it was considered to be a source of poetic inspiration. The nymph is called a daughter of the river-god Permessus (called Termessus by Pausanias). Ovid associates Aganippe with Hippocrene.
