Spiranthes igniorchis, or fire ladies' tresses, is a species of orchid endemic to Florida.

[1][2] Spiranthes igniorchis is endemic to southern-central Florida and only grows in burnt seasonally wet grassland.

Based on molecular analysis of collected specimens they determined those plants to be a sister species to Spiranthes longilabris within the Spiranthes cernua species complex.

Extensive herbarium searches among similarly looking Spiranthes specimens (but labelled as different species) found no other plants and none are known to have been collected prior to specimens collected by S. L. Orzell and E. Bridges in 2014 in Polk County, Florida.

This indicates the species is endemic to a small area in the Osceola Plain of southern-central Florida.
