'''''Phragmites australis''''', the '''Common Reed''' (see [[Reed (plant)]] for other species also called 'reed'), is a large [[perennial plant|perennial]] [[Poaceae|grass]] native to [[wetland]] sites throughout temperate and tropical regions of the world. It is generally regarded as the sole species of the genus '''''Phragmites''''', though some [[botanist]]s divide the genus into three or four species.

It commonly forms extensive stands, up to a square kilometre or more (known as [[reedbed]]s); where conditions are suitable, it can spread at up to 5&nbsp;m or more per year by horizontal '[[runner (botany)|runner]]' stems, which put down [[root]]s at regular intervals. The erect stems grow to 2&ndash;6&nbsp;m tall, with the taller plants growing in areas with hot summers and fertile growing conditions. The [[leaf|leaves]] are broad for a grass, 20&ndash;50&nbsp;cm long and 2&ndash;3&nbsp;cm broad. The [[flower]]s are produced in a dense, dark purple [[panicle]] 20&ndash;50&nbsp;cm long.

The Common Reed is a very important plant for wildlife and conservation, particularly in [[Europe]] and [[Asia]], where several species of [[bird]]s are strongly tied to large ''Phragmites'' stands, notably:-

In [[North America]], the species' status was misunderstood. It was commonly considered to be an [[exotic species]], not native but introduced from Europe; however, there is clear evidence of the existence of ''Phragmites'' native in North America long before European colonisation of the continent. It is now known that the North American native forms of ''Phragmites'' are markedly less vigorous than European forms; the recent marked increase in ''Phragmites'' in North America may be due to a vigorous, but otherwise almost indistinguishable European form of the species, best detectable by [[genetics|genetic]] analysis. This is causing serious problems for many other North American wetland plants, including the local form of the species.<ref>http://www.issg.org/database/species/ecology.asp?si=301&fr=1&sts=</ref>

Recent studies have characterised morphological variation among the introduced and native stands of ''Phragmites'' in North America. The Eurasian genotype can be distinguished from the North American genotype by its shorter ligules (up to 0.9&nbsp;mm vs. over 1.0&nbsp;mm), shorter glumes (under 3.2&nbsp;mm vs. over 3.2&nbsp;mm, although there is some overlap in this character), and culm characteristics.  Recently, the North American genotype has been described as a distinct subspecies, ''Phragmites australis'' subsp. ''americanus'' Saltonstall, Peterson, and Soreng; the Eurasian genotype is referred to as ''Phragmites australis'' subsp. ''australis''. Rhizomes of the plant are rich in [[dimethyltryptamine|N,N-DMT]] alkaloids (Wassel et al. 1985).

One reference to reeds in European literature is Frenchman [[Blaise Pascal]]'s saying that Man is but a 'thinking reed' (''roseau pensant''). In [[Jean de La Fontaine|La Fontaine]]'s famous fable (''Le chêne et le roseau''), the reed tells the proud [[oak]]: "I bend, and break not" ("''Je plie, et ne romps pas''"), before the tree's fall.
