Spiranthes lucida, the shining ladies'-tresses, is a species of orchid native to northeastern North America.
Spiranthes lucida is a perennial, herbaceous plant up to 37 cm tall. The 3-4 leaves are basal, and persist after flowering time, unlike many other Spiranthes species. This is one of the earliest flowering species of ladies'-tresses, with flowers produced between May and August. The flowers are arranged spirally on a single spike. The flowers are white, with a prominent brilliant yellow lip. [2]
Spiranthes lucida occurs from Nova Scotia to northeastern Wisconsin, south to Virginia, Arkansas, and Missouri. [2] It occurs in saturated, calcareous, sandy or gravelly soils found in habitats such as riverbanks, fens, seeps, and gravel pits. [2] [3]
Bees in the family Halictidae have been observed visiting the flowers. [3] The flower morphology is better adapted for short-tongued bees like these than for longer-tongued bees such as bumblebees, unlike most other Spiranthes species. [4]
Spiranthes is a genus of orchids in the subfamily Orchidoideae. They are known commonly as ladies tresses, ladies'-tresses, or lady's tresses. The genus is distributed in the Americas, Eurasia, and Australia. The genus name Spiranthes is derived from the Greek speira ("coil") and anthos ("flower"), and was inspired by the spirally arranged inflorescence.
Spiranthes spiralis, commonly known as autumn lady's-tresses, is an orchid that grows in Europe and adjacent North Africa and Asia. It is a small grey-green plant. It forms a rosette of four to five pointed, sessile, ovate leaves about 3 cm (1.2 in) in length. In late summer an unbranched stem of about 10–15 cm (3.9–5.9 in) tall is produced with approximately four sheath-shaped leaves. The white flowers are about 5 mm (0.20 in) long and have a green spot on the lower lip. They are arranged in a helix around the upper half of the stalk. The species is listed in Appendix II of CITES as a species that is not currently threatened with extinction but that may become so. Autumn lady's-tresses are legally protected in Belgium and the Netherlands.
Spiranthes romanzoffiana, commonly known as hooded lady's tresses or Irish lady's-tresses, is a species of orchid.

It is native to the western United States from Washington and Idaho to southern California. It can be found in moist habitats, such as mountain meadows, swamps, fens, and riverbanks. It is a perennial herb growing from a tuberous root system, reaching a maximum height around 60 cm (24 in). The leaves are mainly located around the base of the erect stem. They are linear or lance-shaped, or sometimes nearly oval. The top of the stem is occupied by the inflorescence, a dense spiral of many flowers. Each flower is somewhat tubular, with an upper and lower lip, and cream to yellowish in color.
