The same and perhaps also allied species are cultivated by negro 

 medical men, who are called "Quibanga" or " Jinganga," in Golungo 

 Alto and Ambriz and other districts; the negro name is " Tuta

 used for witchcraft together with Caladium, but Welwitsch failed to 

 learn for what particular purpose.
