Taxon details Fabaceae is the third largest family of flowering plants, behind Orchidaceae and Asteraceae, with 730 genera and over 19,400 species. Found worldwide, this family contains many agronomically important plants such as Soybean, Phaseolus (beans), Green peas, Chickpeas, Alfalfa, Peanut,Carob), and Glycyrrhiza glabra (licorice). It has been suggested, based on fossil and phylogenetic evidence, that legumes originally evolved in arid and/or semi-arid regions along the Tethys seaway during the early Tertiary (Schrire2005). However, others contend that Africa (or even the Americas) cannot yet be ruled out as the origin of the family (Pan2010). Schrire2005,Pan2010,Wikipedia
Taxon morphology details 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. (Source:Hawaii Botany) Hawaii Botany
