Rank ReasonsA Southeastern Coastal Plain endemic, Spiranthes longilabris is known from North and South Carolina, where it is rare, south to Florida and west to Texas. This taxon is threatened by an increase in competing grass-sedge and woody vegetation which develops in the absence of fire. Drainage of sites would eliminate this species.
Range Extent CommentsA Southeastern Coastal Plain endemic, ranging from southeastern North Carolina south to Florida and west to Louisiana (Weakley, 1996) and Texas (Kartesz, 1998).
Threat Impact CommentsThreatened by an increase in competing grass-sedge and woody vegetation which develops in the absence of fire. Drainage of the site would eliminate this species.
