steppe: Nepeta juncea steppe: Salvia cabulica steppe: Cymbopogan commutatus steppe: Chrysopogan aucheri steppe: Sophora mollis steppe: Astragalus stocksii steppe: Prunus brahuica steppe: Individual communities in each steppe tyoe also segregated on the basis of edaphic factors. The remaining 12 communities could not be classified because they were disjunct types.
