Spiranthes infernalis is known only from Ash Meadows, Nye County, Nevada, and it is probably endemic. The description is based on correspondingly few specimens and may prove to be too restrictive.

Spiranthes infernalis, common name Ash Meadows lady's tresses,[2] is a rare species of orchid known from only four locations in Nevada, all close to one another. The type locale is inside Ash Meadows National Wildlife Refuge, in Nye County approximately 90 miles (140 km) WNW of Las Vegas. The site is a seasonally wet meadow.[3][4][5]
The epithet infernalis means "of the underworld" or "of the nether regions", in reference to the extremely hot climate of the region.[3]
