Araceae  

Family Araceae or Arum family is a big family of herbaceous monocot plant. This family composes 125 genera and 3,750 species. It is distributed from North America, South America, Africa, Europe, Asia to Australia (International Aroid Society, Inc., 2012). The origin and evolution of the Araceae is still poorly known. This might be the herbaceous life form makes them unlikely to fossilize. The oldest reported fossils are pollen grains from the late Barremian-early Aptian, 120 million years ago. The fossil recorded inhabited ponds, lakes or flooded areas. The geographic distribution in the past was driven largely by the global climate (Harendeen and Crane, 1995; Herrera et al., 2008).
