Soda stocksii is a sturdy, glabrous or pruinose shrub 25–80 cm tall, its branches are prostrate or ascending. The distinct, sessile, spreading leaves are terete, fleshy, to 5 mm long and 1,5 mm in diameter. The opposite branches spread nearly horizontally. The inflorescences are wide panicles with 3–12 cm long spike-like branches with numerous flowers. Perianth segments are only 1,5 mm long. The 5 stamens are alternating with ovate staminodes. Fruiting, the perianth segments develop spreading brown wings, circa 6 mm in diameter. The seed diameter is 2,5–3 mm.
Seidlitzia stocksii is pollinated by small wild bees (Hymenoptera), that were observed to collect pollen (see photo).[8] The winged fruits are dispersed by the wind (anemochory).
Seidlitzia stocksii is distributed in Afghanistan, Pakistan and West India (Punjab, Rajasthan), where it grows on sandy or loamy saline soils (halophyte) and limestone hills.[5]
Seidlitzia stocksii is used as a source of crude sodium carbonate[5] (barilla or sajji-khar). The sajji-khar is added as an ingredient for unique taste of papad, a crispy flatbread. The ash of this plant is used as substitute of soap for cleaning clothes and is also taken with water for treatment of internal ulcers.
