Spiranthes ovalis, commonly called the October lady's tresses,[1] 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.[2] However, it is uncommon throughout most of its range,[3] which has resulted in a patchy known distribution. Its natural habitat is in wet to mesic forests and woodlands.[3][4]
It produces delicate white flowers in the fall.[5] 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.[3][4]
Taxonomy
Two varieties of Spiranthes ovalis are recognized.[6] They are:
- S. ovalis var. erostellata - Flowers closed, self-pollinating; widespread across the eastern North America
- S. ovalis var. ovalis - Flowers open, cross-pollinating; restricted to the Southeastern Coastal Plain
