Spiranthes diluvialis, also known as the Rocky Mountain lady's tresses orchid or Ute ladies'-tresses, is native to the western United States, particularly the Rocky Mountains. It can be found in states such as Colorado, Montana, Wyoming, and Utah. It grows in moist, grassy meadows and along streams and rivers at elevations of 1,800 to 3,600 meters (6,000 to 12,000 feet). Spiranthes diluvialis is a small, delicate orchid with white or pale pink flowers that are arranged in a spiral pattern along a slender stem. It blooms in late summer and early fall and is known for its fragrant flowers.

Spiranthes diluvialis is significant because it is a rare species of wild orchid found in the western United States. It is an indicator species that can be used to determine the health of wetland habitats, and its conservation helps to preserve fragile ecosystems. As a result, Spiranthes diluvialis helps to maintain biological diversity and help protect some of nature’s most unique environments.

Threats to Spiranthes diluvialis include habitat destruction, pollution, invasive species, and climate change. Habitat destruction occurs from land development and other forms of land use such as logging, road construction, and farming. Pollution can come from sources like air pollution, water pollution, and pesticides. Invasive species outcompete native species for resources. Finally, climate change has caused changes in water availability and temperature which can have a negative impact on the species ability to reproduce.
