Morphology General Habit
Prostrate, much-branched, succulent annual forming a spreading mat, or infrequently ascending, stems and leaves green or flushed red.
Morphology Leaves
Leaves alternate, subopposite on the branchlets, narrowly obovate to spatulate, 5–30 mm long, 3–10 mm wide, apex rounded, cuneate to a petiole 1–3 mm long; axillary hairs 0.6–1 mm long, inconspicuous, old stems glabrescent.
Morphology Reproductive morphology Inflorescences
Flowers in sessile clusters of 3–8 at the branch tips, encircled by several involucral leaves enclosing ovate-cuspidate scales, frequently overtopped by subsequent growth from the axils of the lower two involucral leaves, the flower-cluster thus seated in a fork, flowers opening in the morning.
