Hab. Cultivated everywhere, Col. Grant! Widely spread in the Old World. 
[^ Nagli ” of India, * murwa” and * ooleyzee” of the African interior. Cultivated everywhere for 
its grain, sometimes in ridges with Indian corn, and at other times, as in the Himalayas, broadcast. Its 
flour, if soaked for a night in water, makes fair unleavened cakes. А coarse bitter-tasting beer, or 
“ pombe,” is made by mixing it with Sorghum. Stirabout is also made from it; and in the prepara- 
tion of plantain-wine, if its parched grain be added, the wine has a pleasant taste of chocolate. It is ripe 
during December at 3° 15’ N. lat.—J. A. G.J |
