Ravenala
''Ravenala madagascariensis'', commonly known as traveller's tree or traveller's palm, is a species of plant from Madagascar. It is not a true palm (family Arecaceae) but a member of a monocotyledonous flowering plant family, Strelitziaceae. ''Ravenala madagascariensis'' is the sole member of the genus ''Ravenala'', and is closely related to the southern African genus ''Strelitzia'' and the South American genus ''Phenakospermum''. Some older classifications include these genera in the banana family (Musaceae). Although it is usually considered to be a single species, four different forms have been distinguished.
==Name==
It has been given the name "traveller's palm" because the sheaths of the stems hold rainwater, which supposedly could be used as an emergency drinking supply for needy travellers. However, the water inside the plant is murky, black and smelly and should not be consumed without purification. Another plausible reason for its name is that the fan tends to grow on an east-west line, providing a crude compass.
The scientific name ''Ravenala'' comes from Malagasy ''ravinala'' meaning "forest leaves".
