Note Granting that several of the synonyms can be segregated fairly distinctly, there nevertheless seems little advantage in so doing. Certainly such segregations intergrade sufficiently to warrant inclusion in one genus, while if considered as separate genera they cause in the herbarium considerable confusion and obscuring of the species, to say nothing of difficulties involved then in the almost impossible task of organizing a usable generic key. Thus, for purposes of the 'Flora of Panama,' Caesalpinia is regarded in its broader sense, essentially following Bentham.
Description Trees, shrubs or sometimes vine-like or subherbaceous, armed or unarmed. Leaves twice-pinnate; petioles and rachis eglandular, glabrous or variously pubes- cent; pinnae usually several and opposite or subopposite on the rachis; ultimate leaflets few to many, opposite in pairs, or less frequently alternate, in the pinna. Inflorescence mostly racemose, variously pubescent; bracts normally caducous. Flowers yellowish or less commonly pinkish; calyx with a conspicuous tube and 5 imbricate lobes, the outermost lobe more or less cucullate and enclosing the bud; petals free, nearly equal, inserted upon the upper calyx-tube; stamens normally 10, free, inserted with the petals on the calyx-tube, usually subdeclinate; filaments mostly pubescent, often glandular; anthers small, bilocular, longitudinally de- hiscent, versatile; ovary free, sessile or short-stipitate, inserted at base of calyx- tube; stigma terminal, usually not dilated. Legume compressed or flattened, usually unarmed and dehiscent; seeds transverse.
