Goodyera repens, an orchid in the genus Goodyera, is called by the common name creeping lady's-tresses in Anglophone Europe[3] and dwarf rattlesnake plantain or lesser rattlesnake plantain in North America.

It is a green underground creeper that sends out occasional skinny stems above the surface. During the summer, these stems bear flowers arranged in a spiral. These flowers twist themselves to face toward the sun.
Goodyera repens is found in isolated spots in the forests and bogs of Europe. It is a rare plant, but it is the most common orchid in Scandinavia.[citation needed] The species is widespread across much of Europe, Asia and North America including Russia, China, Germany, Poland, the United Kingdom, Canada and the United States, though never very common in any of these places.[4][5][6]
Goodyera repens is a protected species throughout most of its range. It does not survive fire, and does not soon reenter an area after fire or logging. It is generally found only in forests at least 95 years old.[7]
Like other orchids, Goodyera repens lives in symbiosis with mycorrhiza, rhizome-dwelling fungus (Ceratobasidium cornigerum or Rhizoctonia goodyearae-repentis). The mycorrhiza help the orchid absorb and assimilate nutrients.
This orchid is pollinated by bumblebees, allowing for its sexual reproduction. It can also reproduce vegetatively. Its seeds are famously minute; only 0.000003 of a gram in weight.[8]

Perspective
Goodyera repens was named Satyrium repens in 1753 by Linnaeus.[2] Many scientists since then have moved the species to another genus, but the accepted name was created in 1813 by the botanist Robert Brown when he moved it to a new genus he named Goodyera. With the rest of its genus it is classified as part of the family Orchidaceae.[2][9] The species has no accepted varieties, but has 25 synonyms.[2]
