Tecticornia pergranulata is a species of small erect sub-shrubs with articulate, succulent stems that grow around 1 meter in height.

They also contain swollen branches with small leaf lobes and are mostly located on the boundaries of salt lakes and salty swamps all across southern Australia.

Through research done by Sarah M Rich, Martha Ludwig, and Timothy Colmer, it was discovered that photosynthesis that takes place within Tecticornia pergranulata roots allows this species to survive through intense flooding.

Larger Tecticornia pergranulata plants grow an extensive system of adventitious roots from their woody basal stem regions.

[3] The photosynthetic process that occurs in this species roots has the potential to supply oxygen to the rest of the plant while facing a flooded habitat.
