Phragmites australis is also reported in East, West and South coastal regions of Saudi Arabia.... and I think Phragmites australis is the only reported species of Phragmites in KSA.. that's why I conclude that its Phragmites australis
It is the common reed, a robust perennial grass, Phragmites australis (Cav.) Trin. ex Steud under the Family Poaceae. Phragmites are reeds of marshy areas and riversides in tropical and temperate regions. It has a worldwide distribution but is native to Europe.
Dear Muhammad Sohaib, You can consult the article- 'Salt tolerance of the reed plant Phragmites communis. April 2006 . In Physiologia Plantarum 72(1): 8-14.

Munira Nasiruddin Thank you so much for referring paper, but I am unable to search this title for the 2006 year. Would you like to share the active link/url to a recommended paper, please!
As to salinity tolerance, Phragmites australis often forms a vegetation belt around inland salt ponds, next to the belt of Puccinellia limosa. At least this is the case in the Hungarian lowland. Experts consider reed as moderately salt tolerant species that can grow in soils with 0.2% total salt content in the A horizon of the soil profile.
