Description: Short description of the legume family with images and descriptions of some genera and species found in Hawaii.
Flowering Plant Families, UH Botany The Fabaceae are mostly herbs but include also shrubs and trees found in both temperate and tropical areas. They comprise one of the largest families of flowering plants, numbering some 400 genera and 10,000 species. The leaves are stipulate, nearly always alternate, and range from pinnately or palmately compound to simple. Like the other legume families the petiole base is commonly enlarged into a pulvinus. The flowers are slightly to strongly perigynous, zygomorphic, and commonly in racemes, spikes, or heads. The perianth commonly consists of a calyx and corolla of 5 segments each. The petals are overlapping (imbricate) in bud with the posterior petal (called the banner or flag) outermost (i.e., exterior) in position. The petals are basically distinct except for variable connation of the two lowermost ones called the keel petals. The lateral petals are often called the wings. The androecium most commonly consists of 10 stamens in two groups (i.e., they are diadelphous with 9 stamens in one bundle and the 10th stamen more or less distinct). The pistil is simple, comprising a single style and stigma, and a superior ovary with one locule containing 2-many marginal ovules. The fruit is usually a legume.
