Indian Cucumber-root (Medeola virginiana), in the Lily family, is an eastern species, growing primarily up through the Appalachians, the mountains of New York and New England, and north into Canada.  This one was found at Cranberry Lake, in the northern NY Adirondacks, on October 8th (from my archives). It's a forest wildflower with edible rhizomes that resemble the taste and odor of cucumbers. The Iroquois also used it medicinally. Sometimes mice eat the seeds and berries.
