Flowers with irregular corollas may be papilionaceous when consisting of five petals of different shapes and sizes: one large distinct, upper and outer (most posterior) petal called the skandard or vexillum, two lateral petals usually smaller than the standard and very different in shape called the wings, and two lower and usually smaller petals which are often slightly connate and embling the prow of a boat, called the keel. The caesalpinaceous flower is similar to the pilionaceous flower but the standard is the smallest and most anterior petal. Irregular corollas that me gamopetalous may be labiates when the limb is 2-lipped, the two upper lobes more or less uniting to from the upper lip and the three lower lobes uniting to form the lower líp; and ligulate or strap- secqped when the tube is short opening out into an elongated narrow, flat, strap-like appendage as in ae ray flowers of some of the Compositae.
