: Fusion, sculptures and ornamentation of the corolla pieces of 17 species of Papilionoideae. The species of subfamily Papilionoideae present flowers with a complex architecture, with elaborated petals in which it has been documented the presence of auricles and callosities, appendixes or spurs that joint the pieces of the corolla and also microsculpturings on the wings. In this study, we analyze the morphology of the petals of 17 species of Papilionoideae (Leguminosae) native of Salta province, Argentina. The lower margins of the keel were fused in all of the species, through different types of fusion of epidermal cells. Only a few species presented fusion in the upper margin of the keel. All the species showed sculpturings in the petals, which would joint some of the pieces of the corolla. They also exhibit ornaments or microsculpturings in the basal region of the adaxial surface of the wings that may act as a grip for pollinators when they land on the flower. The petals of the Papilionoideae flowers presented characteristics that could restrict the type of pollinator able to activate the different mechanisms of pollination that allow them to access the rewards enclosed by the keel.Downloads
