Do Cabomba and Aeonium both belong to the same family?
Cabomba Cabomba is an aquatic plant genus, one of two belonging to the family Cabombaceae. It has divided submerged leaves in the shape of a fan (hence the vernacular name fanwort) and is much favoured by aquarists as an ornamental and oxygenating plant for fish tanks. Use in the aquarium trade has led to some species being introduced to other parts of the world, such as Australia, where they have become weeds.
Galium aetnicum Galium aetnicum (common name Mount Aetna bedstraw) is a plant species in the Rubiaceae. The species is named for Mount Etna, the large and active volcano on the island of Sicily in the Mediterranean. The species is native to the island, and also to the Lazio and Abruzzo regions of mainland Italy. There are reports of the plant growing in Sardinia as well, but these are unconfirmed.
