Stems are richly branched and glabrous with ultimate young branches generally pendulous, green, succulent and thin (1-1.5 mm), older branches silvery-whithe to yellowish-white. Leaf are scale-like, pairs, opposite, connate into a cup with a tuft of short hairs in the axil. Flowers are 2-bracteolate, bisexual, born on very thin (1-1.5mm thick) lateral or terminal branchlet with thin, membranous, glabrous staminodes and 5 stigmas.

    • Remarks
      White Saxaul is an emblematic species in the arid land and the only tree growing in dunes deep mobile sand. Even after its death, a dense ring of annual plants often persists around it, supported by enriched soil organic matter, accumulated nutrients, and wind-blown seeds that enhance the local seed bank. This species plays a key ecological role by trapping sand at its base, forming small dune-like mounds (hummocks) that serve as important microhabitats and shelter for various desert wildlife, including rodents, snakes, and scorpions. This species is often paratized by an insect-gall, making the branches shorter with generally a few hypertrophied leaf-pairs.
