Monotropsis

Monotropsis is a monotypic genus of plants containing the single species Monotropsis odorata, also known as sweet pinesap or pygmy pipes. It is a member of the subfamily Monotropoideae of the heath family, Ericaceae. It is native to the Appalachian Mountains in the south-eastern United States, and is viewed as being uncommon throughout its range.

Like all members of the subfamily, Monotropsis odorata does not contain chlorophyll; it is a myco-heterotroph, getting its food through parasitism upon fungi rather than photosynthesis. These fungi form a mycorrhiza with nearby tree species.

M. oderata has a sweet smell which has been likened to nutmeg, cinnamon or violets.
