''Haloxylon persicum'', the white saxaul, is a small tree belonging to the family Amaranthaceae. Its range is Western Asia, including Israel, Jordan, Egypt, Sinai, South Iraq, Saudi Arabia, Iran, Oman, UAE, Afghanistan, and Pakistan, to Central Asia (Kyrgyzstan, Turkmenistan, etc.), and China (Xinjiang etc.). ==Description== The ''Haloxylon persicum'' has a stout rugged stem and light grey bark, growing up to 4.5-5 metres in height. It lacks large foliage-type leaves; in fact, its leaves have retrogressed as succulent branches. The plant is found in sandhills, deserts and sand ridges, where it often forms pure stands, with an average density up to 400-500 trees a hectare. The white saxaul is a hardy tree that can grow in nutritionally poor soil and can tolerate drought. The tree is in leaf all year, and flowers in May-June.
