Convergent inflorescence morphology in the mimosoid legume genera Parkia (right) and Dichrostachys (left). Parkia nitida Miquel from Ecuador has pendant inflorescences specialized for bat-pollination. The basal flowers are sterile, with white staminodia forming a fringe that overhangs the nectar-producing flowers; the yellow distal flowers are bisexual. Inflorescences of Dichrostachys cinerea (L). Wight and Arnott also have a staminodial fringe, but the staminodia are rose colored when the flowers first open, and gradually change to white postanthesis. These inflorescences also lack specialized nectar-producing flowers, and are presumably entomophilous.
