Fruit: capsule [ berry, drupe].
4 genera, 16 species: generally ± arid regions, n hemisphere, Australia. [The Angiosperm Phylogeny Group 2003 Bot J Linn Soc 141:399–436] Based on molecular, anatomical, and morphological evidence, The Angiosperm Phylogeny Group (2003) indicates that Peganum and Nitraria, sometimes placed in Zygophyllaceae, are widely separated from Zygophyllaceae sensu stricto, and probably should be placed in a different family, in a different order (Sapindales) than Zygophyllaceae (Zygophyllales). —Scientific Editor: Thomas J. Rosatti.
Plant < 1 m; branches, leaves dense.
