A. SORGHUM, Brot., Karal-iring-u, S., known as Sorgho, Imphee? 

 Indian Millet, Jowar, Chinese Sugar-cane, and other names, is cultivated 

 under various forms throughout the Tropics, but apparently rarely in 

 Ceylon, for its grain, and as a fodder grass. It is a tall very robust 

 annual, sometimes 20 ft. high, with a large usually drooping head, of often 

 globose, pale, or dark spikelets. It has been supposed to be a cultivated 

 state of A. halepensis, of very early unknown origin. There is a specimen 

 of it» in the Peradeniya Herbarium, labelled ' 196, Truuka, or Talai- 

 virichehan ; Mannar (Crawfurd).' It is the 'Durra' of Tropical Africa.
