Aristolochia gigantea Mart. & Zucc.

Description: The flowers grow in the leaf axils. They are inflated and globose at the base, continuing as a long calyx and corolla of a flower (generally used when the two are similar).">perianth tube, ending in a tongue-shaped, brightly colored lobe. There is no corolla.
These flowers have a specialized pollination mechanism. The plants are aromatic and their scent attracts insects. The inner part of the perianth tube is covered with hairs, acting as a fly-trap. These hairs then wither to release the fly, covered with pollen.²
