Flower/Fruit: Fl. & Fr. Per.: July-October.
Type: Type: Australia, Nee (MA).
Distribution: Distribution: Pakistan (Punjab & Kashmir); temperate regions of both hemispheres in the Old World and the New.
Comment/Acknowledgements: Plants with short, convolute, pungent leaf-blades and sheaths less than 3 cm long have been separated as var. stenophylla (Boiss.) Bor. Clayton (1967), however, has pointed out that shoots displaying this habit can occasionally be found growing from normal plants of both this species and Phragmites karka, and for this reason the variety is hardly worthy of recognition.

Common or Ditch Reed is found on limestone slopes in open forest in the mountains, margins of lakes and ponds and in shallow water in the plains.
