What is the designated names for the petals of a legume flower?

The designated names for the petals of a legume flower are collectively referred to as the "corolla." In legumes, the corolla typically consists of five petals: one large petal called the "standard" or "banner," two lateral petals known as "wings," and two smaller petals that are fused together at the base, called the "keel." This unique arrangement aids in attracting pollinators and facilitating reproduction.
