'Sands of Goravan is the only place in Armenia where relict phog ("Calligonum
"), and Rhynopetalum gibbosum occur. It is a leafless perennial shrub with dense white and green branches up to 1m long. Its roots are important for preventing sand movement.

Local people collecting roots and branches of the phog and use it as fuel. Also phog is intensively grazed by domestic goat and sheep.
, locally known as "phog" (), is a small shrub found in Thar desert areas, usually 4 feet to 6 feet high but occasionally may reach even 10 feet in height with a girth of 1 to 2 ft.

is a species of flowering plant in the buckwheat family known by the common name knotweed spineflower. It is native to California and Baja California, where it grows widely scattered in many types of habitat. It is a petite plant taking a prostrate form with stems just a few centimeters long at maximum. It may be green to red in color and is hairy in texture. The leaves are no more than a centimeter long and the flower is under two millimeters wide. The minute flower is surrounded by three hairy point-tipped bracts.
The plant is diminutive, and a hand-lens is necessary for proper identification. The plant is very sensitive to temperature and precipitation, and under drought or hot conditions the seeds will not germinate or survive. The plant is visible anywhere from February through July during good rain year, but most years the plant is only visible from April to June. Each minute flower yields one seed. This species is octoploid and probably arose through hybridization between other "Chorizanthe", perhaps "C. procumbens" and "C.
Many species of sand-dwelling plants form nabkhas. In the Chihuahuan Desert they include soaptree ("Yucca elata"), creosote ("Larrea tridentata"), and atriplex ("Atriplex" spp.). In China nabkhas form quite often around "Caragana microphylla", as well as "Cleistogenes squarrosa", "Leymus chinensis", "Caragana stenophylla", "Stipa grandis", and "S. glareosa", plus tamarisks, reeds, and alhagi. In Jal Az-Zor National Park in Kuwait, they occur around "Nitraria retusa", "Zygophyllum qatarense", "Haloxylon salicornicum", and "Panicum turgidum". Halophytes such as "Tamarix aucheriana", "Halocnemum strobilaceum" and "Salicornia europaea" have nabkhas in saline soils, while "Cyperus conglomeratus", "Rhanterium epapposum", "Astragalus spinosus", "Lycium shawii", and "Citrulus colocynthis" are seen in non-saline zones. On the Sinai Peninsula of Egypt they are recorded on "Artemisia monosperma", "Moltkiopsis ciliata", "Calligonum
