Spiranthes triloba, the panther ladies' tresses (previously sometimes green-lipped Spiranthes odorata) is a terrestrial orchid endemic to Florida. [1] [2]
Spiranthes triloba plants have up to 5 basal leaves that can sometimes be wilted by the time they are flowering. The flowers are white and fragrant and arranged in a spiral around the stem. The lip of each flower is green for newly opened flowers and changes to yellow over time. Bloom time is during winter, from October to February. [1]
They look similar to Spiranthes odorata and Spiranthes cernua but the lip changing in color from green to yellow clearly distinguishes them from either. In fact locals in Florida long knew that there were Spiranthes odorata plants with this difference in appearance and called them green-lipped Spiranthes odorata. [2]
The common name panther ladies' tresses is an homage to the Florida panther which is also endemic to Florida and lives in the same habitat as these flowers.
Spiranthes triloba is endemic to Florida and prefers frequently burned prairies. This habitat is distinct from that of Spiranthes odorata which prefers flooded forests. [2]
The Spiranthes triloba plants were first described by John Kunkel Small in 1898 as Gyrostachys triloba and transferred to Spiranthes triloba by Karl Moritz Schumann in the same year. However, for the next 118 years Spiranthes triloba was rarely considered a separate species and included as a variation of Spiranthes cernua or Spiranthes odorata (which itself was often considered a variation of Spiranthes cernua). M. C. Pace conducted a phylogenetic and morphological study in 2016 and reinstantiated it as a separate species under Schumann's original name. [3] [2]
Spiranthes is a genus of orchids in the subfamily Orchidoideae. They are known commonly as ladies tresses, ladies'-tresses, or lady's tresses. The genus is distributed in the Americas, Eurasia, and Australia. The genus name Spiranthes is derived from the Greek speira ("coil") and anthos ("flower"), and was inspired by the spirally arranged inflorescence.
Spiranthes romanzoffiana, commonly known as hooded lady's tresses or Irish lady's-tresses, is a species of orchid.

An occurrence was recently discovered in southern British Columbia. The plant faces a number of threats to its existence. It is a federally listed threatened species of the United States.
Spiranthes magnicamporum, commonly called the Great Plains lady's tresses, is a species of orchid that is native to North America. It is primarily native in the Great Plains, but there are outlying populations in the east in areas of former natural grassland, such as the Black Belt prairies of the Southeast. It is found in both fens and wet and dry prairies, often in calcareous soil.

Spiranthes incurva, the Sphinx ladies' tresses, is a species of flowering plant in the family Orchidaceae. This orchid is native to the upper Midwest and Great Lakes Basin of North America. The species was originally described as Ibidium incurvumJenn. in 1906. Long treated as part of a sensu latoSpiranthes cernua, the species complex was reevaluated and Spiranthes incurva reestablished as a separate species in 2017. Spiranthes incurva is an ancient natural hybrid of S. cernuasensu stricto and S. magnicamporum.
Spiranthes arcisepala, the Appalachian ladies' tresses, is a species of flowering plant in the family Orchidaceae. This orchid is native to eastern North America. Long treated as part of Spiranthes cernua the species complex was reevaluated and Spiranthes arcisepala established as a separate species in 2017.
