Missouri Orchids – Liparis loeselii – Fen Twayblade

Liparis loeselii (fen twayblade, Loesel’s twayblade) is ranked as imperiled in the state of Missouri. We found these in a marly fen in Butler County, MO in bloom during late May, 2021. Within this fen, these orchids grow on the edges between small tussocks and the marl/muck, out of the way of larger competitive plants.

It may come as no surprise, due to the plain and diminutive flowers of Liparis loeselii, but this plant is considered autogamous (self-fertilizing).
