Spiranthes laciniata, the lacelip ladies' tresses is a terrestrial orchid endemic to the south eastern United States.
Spiranthes laciniata plants are a tall species of Spiranthes reaching a height of 20–95 cm, with up to 5 basal leaves persisting through anthesis. The flowers are white to cream-white and arranged in a spiral around the stem. The lip is usually yellow in the center. Bloom time is from May to (at its northern range) September.
Spiranthes laciniata is native to the southeastern coastal plains, from Texas in the south all the way to New Jersey in the north.
It is a wetland plant and grows in swamps and marshes, sometimes even in standing water.
The Spiranthes laciniata name was first published by Oakes Ames in 1905, after John Kunkel Small had described the plants in 1903 as Gyrostachys laciniata.
