Reed

reed, name used for several plants of the family Graminae (grass family). The common American reed, also called reedgrass and canegrass, is a tall perennial grass (Phragmites australis), widely distributed in fresh or brackish wet places. It has stout, creeping rootstalks and a large plumelike panicle. In the SW United States this grass is called carrizo and is used in building adobe huts; it has also been used for thatching and cordage. Native Americans collected a sweet exudate from the plant and made arrows of the stalks. The leaves served as edible greens and the seeds as a cereal food. Due in part to the degradation of salt marshes and in part to the supplanting of the native P. australis by a Eurasian variety, the reed has become invasive in American wetlands, where it often forms a monoculture. The giant reed (Arundo donax), of similar appearance, is native to the Mediterranean region but is now widely naturalized throughout tropical and warm climates, including the S United States. It is often cultivated for ornament, and in Europe the stems have been used to make reed instruments, bagpipes, and reed organs. This is the reed from which Pan was fabled to have made his panpipe, or syrinx. The "reeds" of wickerwork are often rattan. Reeds are classified in the division Magnoliophyta, class Liliopsida, order Cyperales, family Gramineae.

reed

In botany, any of several species of large aquatic grasses, especially the four species in the genus Phragmites (family Poaceae, or Gramineae). The common, or water, reed (P. australis) occurs along the margins of lakes, fens, marshes, and streams from the Arctic to the tropics. It is a broad-leaved grass, about 5–15 ft (1.5–5 m) tall, with feathery flower clusters and stiff, smooth stems. Bur reed (genus Sparganium) and reed mace (genus Typha) are plants of other families. Dried reed stems have been used for millennia as thatching and construction material, in basketry, for arrows and pens, and in musical instruments (see reed instruments).

Reed 

the sound-producing agent of many musical instruments. The reed is a small plate, fixed at one end, that is caused to vibrate. The vibrations are produced by passing a stream of air over the reed or by plucking or striking it. Reeds are divided into two types: free and beating. Free reeds, which are set in a frame with an opening, are found in the accordion, baian, harmonica, and harmonium. Beating reeds are subdivided into those that are actually made of reed and those that are made of metal. The former make up part of the sound-producing mechanism of such reed instruments as the clarinet, oboe, and bassoon. Metal reeds are used principally in the pipes of reed organs.
