RANGE: A salt-tolerant plant partial to damp, saline soils. Found in flood basins adjacent to the rivers or in poorly drained low spots. Agricultural fields that have become saline and unproductive are colonized by this plant.

SHRUB: A woody shrub, mostly to 1 meter tall, occasionally 2 meters. The much-branched stems appear thick, fleshy and segmented; the surface is green and photosynthetic.

LEAVES: Virtually leafless - the actual leaves are short and scale-like.
