Generally cultivated in Egypt; but notwithstanding 

 Boissier^s remark " spontaneous in sandy places," I cannot 

 say I have seen it so. Its seeds are edible, which is

 the muddy banks of the receding Nile broadcast without 

 being covered. The bitter seed becomes sweet during 

 germination, owing to the transformation of its starch into 

 sugar. In this state of germination the seeds have been 

 an article of consumption among all the nations at one 

 time or other subdued by the Arabs.
