Spiranthes lacera, commonly called the slender ladies'-tresses, is a species of orchid that is native to Eastern North America. It has a widespread range and is found in a variety of open habitats, both natural and disturbed. It produces a spiral of white flowers in the summer.
There are two varieties recognized:[1][2]
- S. lacera var. gracilis - Southern slender ladies' tresses, flowers more densely arranged in spiral, blooming later (late-July through August). Plant hairless and leaves usually absent at flowering.
- S. lacera var. lacera - Northern slender ladies' tresses, flowers more loosely arranged in spiral, blooming earlier (mid-July). Plant hairy and leaves usually present at flowering.
