Cyperus papyrus (papyrus sedge or paper reed) is a monocot belonging to the sedge family Cyperaceae. It is a herbaceous perennial native to Africa, and forms tall stands of reed-like swamp vegetation in shallow water.

Papyrus sedge (and its close relatives) has a very long history of use by humans, notably by the Ancient Egyptians—it is the source of papyrus paper, parts of it can be eaten, and the highly buoyant stems can be made into boats. It is now often cultivated as an ornamental plant.

Description

This tall, robust, leafless aquatic plant can grow 4 to 5 m (13 to 16 ft) high. It forms a grass-like clump of triangular green stems that rise up from thick, woody rhizomes. Each stem is topped by a dense cluster of thin, bright green, thread-like stems around 10 to 30 cm (4 to 10 in) in length, resembling a feather duster when the plant is young. Greenish-brown flower clusters eventually appear at the ends of the rays, giving way to brown, nut-like fruits.

The younger parts of the rhizome are covered by red-brown, papery, triangular scales, which also cover the base of the culms. Botanically these represent reduced leaves, so strictly it is not quite correct to call this plant fully "leafless".

Papyrus in history

Egyptians used the plant for many purposes, most famously for making papyrus paper. Its name in Greek and in English is widely believed to have come from Egyptian. Cyperus papyrus is now used mainly for decoration, as it is nearly extinct in its native habitat in the Nile Delta, where in ancient times it was widely cultivated. Theophrastus' "History of Plants" (Book iv. 10) states that it grew in Syria; and, according to Pliny's Natural History, it was also a native plant of the Niger River and the Euphrates.

Aside from papyrus, several other members of the genus Cyperus may actually have been involved in the multiple uses Egyptians found for the plant. Its flowering heads were linked to make garlands for the gods in gratitude. The pith of young shoots was eaten both cooked and raw. Its woody root made bowls and other utensils and was burned for fuel. From the stems were made reed boats (seen in bas-reliefs of the Fourth Dynasty showing men cutting papyrus to build a boat; similar boats are still made in the southern Sudan), sails, mats, cloth, cordage, and sandals. Theophrastus states that King Antigonus made the rigging of his fleet of papyrus, an old practice illustrated by the ship's cable, wherewith the doors were fastened when Odysseus slew the suitors in his hall (Odyssey xxi. 390).
