Flower/Fruit: Fl. Per.: June-September.
Type: Type: In arena insularum Tigridis prope Mossul, 2nd Sept. 1841, Kotschy (specimena fructifera).
Habitat: An Irano-Turanian element, occurring between 1500-2500 m near water channels and also grows as a weed. Often confused with P. patulum M. Bieb. due to similar habit and almost leafless floral branches which are conspicuously different from the leafy vegetative branches in both the taxa. However, in P. argyrocoleum the inflorescence is compact and the nuts are small. Whereas in P. patulum the inflorescence is lax, interrupted and the nuts are large.
Distribution: Distribution: Iraq, Iran, Pakistan, Afghanistan, Central Asia including Turkmenistan, Georgia (Caucasia).
