''Haloxylon'' and its species are known by the common name '''saxaul'''. "Saksaul" is a common [Turkic](/source/Turkic_languages) word{{cite journal |last1=Каримуллина |first1=Г.

The branches of the current year are green, from erect to pendant. The leaves are reduced to small scales. The [inflorescence](/source/inflorescence)s are short shoots borne on the stems of the previous year. The flowers are very small, as long or shorter than the [bracteole](/source/bracteole)s, bisexual or male. The two [stigma](/source/Stigma_(botany))s are very short. In fruit, the [perianth](/source/perianth) segments develop spreading wings. The fruit with wings is about {{convert|8|mm|in|frac=4}} in diameter. The seed is about {{convert|1.5|mm|2|abbr=on|frac=64}} in diameter.{{cite book|first=I.

''[Plants of the World Online](/source/Plants_of_the_World_Online)'' includes 11 species {{As of|2026|02|lc=y}}, as follows:{{R|POWO}} *''[Haloxylon ammodendron](/source/Haloxylon_ammodendron)'' {{Au|(C.A.Mey.)

They are now classified to genus ''[Hammada](/source/Hammada_(plant))''; the former ''Haloxylon stocksii'' (syn. ''Haloxylon recurvum'') has been moved to ''[Soda stocksii](/source/Soda_stocksii)''. The common name ''saxaul'', sometimes ''sacsaoul'' or ''saksaul'', comes from the Russian ''саксаул'' (''saksaul''), which is from Kazakh ''сексеуiл'' (''seksewil''). ==Ecology== In the deserts of [Central Asia](/source/Central_Asia), a large number of birds are associated with saxaul, including the [saxaul sparrow](/source/saxaul_sparrow).{{cite journal|last=Maclean|first=Gordon Lindsay|year=1996|url=http://espace.lis.curtin.edu.au/archive/00000320/01/Bulletin_17.pdf|title=Avian adaptations to deserts of the Northern and Southern hemispheres: a comparison|journal=Curtin University of Technology School of Environmental Biology Bulletin|issue=17|access-date=2010-02-16|archive-url=https://web.archive.org/web/20080726022938/http://espace.lis.curtin.edu.au/archive/00000320/01/Bulletin_17.pdf|archive-date=2008-07-26|url-status=dead}} == Uses == The trees are used by nomads across the steppes of Central Asia as firewood.{{cite book |title=Jangar: The Heroic Epic of the Kalmyk Nomads |first=Saglar |last=Bougdaeva |date=10 January 2023 |publisher=U of California P |page=252 |isbn=9780520344723 |location=Oakland}} In the former bed of the [Aral Sea](/source/Aral_Sea), saxaul trees are being planted to stop the wind picking up contaminated sand from the dried up sea bed and spreading them through the atmosphere.
