Spiranthes L. C. Rich.
The Ladies'-tresses orchids
Spiranthes cernua, Nodding Ladies'-tresses
The name Spiranthes
is derived from the Greek for coiled ("spir") flowers ("anthes"),
an allusion to the typically spiralled arrangement of the inflorescence.
Taxonomic delimitation of the genus is very unclear, with the best estimate
of size being approximately 300 species worldwide. Wisconsin, however, is
home to only six species. These can be difficult to distinguish from each
other, but with practice, they can be reliably determined from fresh material.
