Texas Ladies' Tresses

Spiranthes brevilabris Lindl.

Comments

provided by eFloras
Spiranthes brevilabris and S. floridana are often and easily confused, although the degree of pubescence is an excellent diagnostic tool in the field.

This species has dramatically declined, with only a single extant population known in 1998–2000.
