Family Caesalpiniaceae

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. -- Gerald Carr
