Spiranthes ovalis

Spiranthes ovalis, commonly called the October lady's tresses, is a species of orchid that is native to eastern North America. Its range is widely distributed, being found from Texas to Florida, north to the Great Lakes. However, it is uncommon throughout most of its range, which has resulted in a patchy known distribution. Its natural habitat is in wet to mesic forests and woodlands. It produces delicate white flowers in the fall. It can be distinguished from other Spiranthes in eastern North America by its small, tightly spiraled flowers, and the presence of basal leaves at flowering time....read more on Wikipedia.
