The Nodding Onion is a perennial in the lily family (Liliaceae) that sports white to pale pink blooms that attract butterflies. This specimen was collected by Anna Pedersen Kummer in 1943 from Stony Island in Chicago, a site that no longer exists. Now this plant is only found in northeastern Illinois.

Kummer was a botanist and served as Curator of Botany at the Chicago Academy of Sciences from the late 1930s to the mid 1940s. She earned her PhD in botany from the University of Chicago and specialized in weedy plants, publishing numerous articles on the value of plains weeds in the prairie ecosystem.
