    Aliopsis pygmaea (Regel & Schmalh.) Omer & Qaiser is a uniregional species belonging to Irano-Turanian region. The species seems to be under collected as few collections are known, including two specimens cited above:

    A small plant of alpine habitat, gr owing near snow water or moist grass lands at an elevation of 14-18000 ft. Ho (1988) recognized both (Aliopsis pygmaea and Aliopsis thomsonii) the species. The two seem to be conspecific.
