Habit: Tree, shrub, with stipular spines at nodes or thorns in leaf axis (see leaf scars) or main leaf axis a strong spine. Stem: +- zigzag; bark smooth, green. Leaf: alternate or in clusters of 1--6 in spine axils, generally even-2-pinnate, sometimes appearing 1-pinnate, main axis flat, leaflets alternate, falling early or not; 1° leaflets 2--6; 2° leaflets 4--many. Inflorescence: raceme, axillary, generally < 7-flowered.

Species In Genus: 11--12 species, 2 named hybrids: America, southern United States to Argentina, Africa; cultivated. Etymology: (J. Parkinson, London, apothecary, author, 1567--1650) Note: Haston et al., Hawkins support treatment of Cercidium and Parkinsonia, both recognized in TJM (1993), as single, monophyletic genus.
Unabridged Note: Since S. Watson (1870s), Cercidium and Parkinsonia have variously been treated as 1 or 2 genera; Carter 1974 and McClintock in TJM (1993) recognized both genera but work of Hawkins 1996 (Ph.D. Dissertation, Univ. Oxford, UK) and Haston et al. 2005 (Amer J Bot 92:1359--1371) support treatment as 1 monophyletic group.
