Bulrush: (or papyrus), a red growing in the shallow water on the banks of the Nile. It grows to the height of 12 or 15 feet, with a stalk two or three inches in diameter. The stalks are very pliable and can be very closely interwoven, as is evident from their having been used in the construction of arks. (Exodus 2:3,5) Paper was made from this plant, from which it derives its name.
