66583 Nicandra           Discovered 1999 Sept. 9 by the Lincoln Laboratory Near-Earth Asteroid Research Team at Socorro.
Named for a monotypic genus of flowering plants in the nightshade family containing the single species Nicandra physalodes. While the genus is named for Greek poet Nicander, it is known by the common names "apple-of-Peru" and "shoo-fly plant." Its flowers are bell-shaped, pale violet with white throats.
