Hab. By the Nile, 16°-17° N. lat., Col. Grant! Also in Egypt, and eastward in 
India. 
[This coarse grass lines the sandbanks of the Nile at 16°-17° N. lat., and was ripe during April. It 
grows 2 to 8 feet high, and would grow higher. I saw the people of “ Ab’idy,” on the Nile, making it 
into a rope, which seemed very tough. The plant helps here to bind the sands on the banks of the river.
