This is a widespread and variable species, reaching the eastern limit of its range in W China. It is sometimes subdivided into more narrowly defined species or infraspecific taxa based on variations in leaf indumentum and spikelet size. Chinese material is referable to subsp. caspia, or Stipa caspia at specific rank. Stipa arabica subsp. arabica from SW Asia has lemmas 7–9 mm and awns not exceeding 9 cm. Stipa turgaica is based on a form with densely pilose leaf blades. Stipa arabica is a good forage grass in desert steppe regions.

The frequently cited reference Stipa szowitsiana Trin. ex Hohen. in Bull. Soc. Nat. Moscou 11:243. 1838 is that of a nomen nudum and does not count for priority. Work is still needed on the infra-specific classification of Stipa arabica, but it seems that in Pakistan it is represented by subsp. caspia (C. Koch) Tzvelev in Nov. Sist. Vyssh. Rast. 11:16. 1974.
