Labellum ± as long as petals, 3.2-4 mm long, 3-lobed near concave base; side lobes short, c.0.6 mm, divergent; mid-lobe narrowly-ligulate, 1.8-2 mm long. Column short, broad.

Type: “Habitat in Europea pratis uligonosis”
The basal part of the labellum of the Himalayan Herminium monorchis is sometimes distinctly conically excavated. More than in the European plants, thus giving the appearance of a short spur.
Distribution: Europe, Himalayan-mountains, Tibet, China, Japan. Euro-Sibirian element. In wet meadows up to 4300 m.
