Arrou. — This herbaceous plant is now generally diffused in maritime districts of Tropical 

 Asia and Africa, and throughout Polynesia, as well as on the coast of North-eastern 

 Australia, but is commonly cultivated for its tuberous roots in Polynesia and in some 

 other parts of its area. It is probably not indigenous in Polynesia, at least in those islands 

 nearest to America. Jouan states that it is rare in the Marquesas Islands, only a few plants 

 being found here and there in shady, humid ravines, and the plant as well as the Tahitian 

 name " Pia" he regards as of comparatively recent introduction into Nukuhiva. Nadeaud 

 mentions that it is often cultivated near houses in Tahiti, and also that it abounds in a wild 

 state in many of the vallevs. Mann treats it as indigenous in the Sandwich Islands, where, 

 according to Seemann, it grows spontaneously in sunny places, and is also cultivated to a 

 considerable extent. It bears the same name, "Pia," in the Sandwich Islands, and indeed 

 throughout Polynesia. Altogether there are nine species of Tacca, three of which arc 

 peculiar to Tropical America, and the rest to the Old World. Tacca palmata, Blume 

 (Tacca montana, Rumph.), or an allied species, occurs in Timor Laut.
