This is a lowlying shrub of the southwestern United States and northern Mexico, where it grows in sandy, often salty, distinctly alkaline soils, such as desert washes and saline dry lakebeds. It is a common member of the alkali flat ecosystem. The knobby green stems are fleshy and appear jointed at the internodes between segments. Often the segments are so short they are nearly round. The leaves appear as flaky scales scattered across the surface of the stems. The genus was named for the English botanist
