It is an erect, diffusely branched shrub, 2 ft. to 5 f t. high, with alternate, fleshy, green, apparently leafless, jointed branches, the leaves being reduced to minute pointed scales or wanting. The
numerous small flowers are arranged spirally by threes in crowded cylindrical spikes, a in. to / in. long, borne in the axils of fleshy bracts near the ends of the branches. In appeatance the plant is suggestive of a tall, much-branched form of the glass-wort (q.v.) or samphire, to which it is closely allied.
