Description: Description of this family of mostly tropical and subtropical trees and shrubs, with photographs of a number of species.
Flowering Plant Families, UH Botany The Caesalpiniaceae are mostly tropical and subtropical trees and shrubs comprising about 150 genera and 2,200 species. The leaves are stipulate, alternate, and mostly pinnately compound but may be bipinnate or simple. Like the other legume families the petiole base is commonly enlarged into a pulvinus. The flowers are in racemes, spikes or cymes, are zygomorphic, and are mostly weakly to strongly perigynous. The perianth commonly consists of a calyx and corolla of 5 segments each; the petals are distinct, overlapping (i.e., imbricate) in bud, with the posterior one (flag or banner) innermost in position. The androecium usually consists of 1-10 distinct or variously united stamens, some of which are commonly reduced to nonfunctional staminodes. The pistil is simple, consisting of one style and stigma, and a superior ovary with one locule containing 2-many marginal ovules. The fruit is usually a legume.
