Nitraria retusa, commonly known as Nitre bush, is a salt-tolerant and drought-resistant shrub in the family Nitrariaceae.

It typically grows in salt marshes and semi-arid saline areas of deserts and it can help in the stabilisation of loose soils.

Near the lake, where salinity is low and the water table high, it associates with the sea rush, the common reed, salt grass and Zygophyllum album.

At the outer fringe of the vegetated zone, where the salinity is high and the water table deep, it grows with Z.album and the Nile tamarisk.

[5] N. retusa is one of a number of salt-tolerant plants that are being investigated as potential fodder crops for livestock.
