Spiranthes is a genus of terrestrial orchids containing around 25 species, distributed across the temperate zones of North and South America, Eurasia, and Australia. The flowers are arranged in a distinctive spiral, twisting into a terminal spike, and are usually white, yellow, or rarely pink. The labellum is usually somewhat linear and lacks a spur. The stems are sometimes covered in thin hairs, and it produces either basal or stem leaves. Species in this genus can be found growing in a wide range of habitats, from meadows and fields to forests.
