Papyrus

Papyrus is a tall aquatic sedge that forms reed-like stands in shallow water. Wikipedia says the ancient Egyptians used it for many purposes, including the paper that took its name, that parts of the plant can be eaten, and that its highly buoyant stems can be made into boats. Cunningham calls it masculine, with Mercury and air, and gives it one power, protection. His only use is a boating one: place papyrus in boats to protect against attacks by crocodiles. He gives it no folk names and no deity. Kynes gives papyrus no entry, so the entry rests on Cunningham and Wikipedia alone.
