We now commonly call the Iris a Flag, and in Shakespeare's time the Iris pseudoacorus was called the Water Flag, and so this passage might, perhaps, have been placed under Flower-de-luce. But I do not think that the Flower-de-luce proper was ever called a Flag at that time, whereas we know that many plants, especially the Reeds and Bulrushes, were called in a general way Flags. This is the case in the Bible, the language of which is always a safe guide in the interpretation of contemporary literature. The mother of Moses having placed the infant in the ark of Bulrushes, "laid it in the Flags by the river's brink," and the daughter of Pharaoh "saw the ark among the Flags." Job asks, "Can the Flag grow without water?" and Isaiah draws the picture of desolation when "the brooks of defence shall be emptied and dried up, and the Reeds and the Flags shall wither." But in these passages, not only is the original word very loosely translated, but the original word itself was so loosely used that long ago Jerome had said it might mean any marsh plant, quidquid in palude virens nascitur. And in the same way I conclude that when Shakespeare named the Flag he meant any long-leaved waterside plant that is swayed to and fro by the stream, and that therefore this passage might very properly have been placed under Rushes.
