Ghost Pipe
Ghost pipe is the common name for *Monotropa uniflora*, a white, non-photosynthetic flowering plant in the heath family that is usually found in shaded forests.
Ghost pipe is the common name for *Monotropa uniflora*, a white, non-photosynthetic flowering plant in the heath family that is usually found in shaded forests. It obtains nutrients indirectly through fungi associated with tree roots, rather than through photosynthesis. The species is native to much of North America and parts of Asia.
Description
Ghost pipe is a herbaceous perennial flowering plant with pale, translucent stems and scale-like leaves. Its lack of chlorophyll gives it a white, waxy appearance, though some individuals may be pinkish or marked with dark specks. The plant typically reaches about 4–8 inches (10–20 cm) in height.
Ecology
Ghost pipe is myco-heterotrophic, meaning it obtains nutrients indirectly through fungi that are connected to tree roots, rather than through photosynthesis. This allows it to grow in deeply shaded, moist forest habitats where sunlight is limited. Its pale appearance often leads to it being mistaken for a fungus.
Taxonomy and naming
Ghost pipe is classified as *Monotropa uniflora* in the family Ericaceae, though it was previously placed in Monotropaceae. The genus name *Monotropa* refers to the recurved stem tip, and the species name *uniflora* means 'one-flowered', referring to the single white flower per stem. The plant flowers mainly from June to September.
Distribution
Ghost pipe is native to much of the United States and is also found in parts of Asia. In Canada, it occurs in southern provinces and is part of the native forest understory flora of eastern and central regions. The plant is absent from some areas, such as much of the Rocky Mountains.
Key facts
- Ghost pipe is a white, waxy woodland plant often mistaken for a fungus.
- It lacks chlorophyll and does not photosynthesize.
- It is myco-heterotrophic, obtaining nutrients through fungi linked to tree roots.
- Each stem usually bears a single flower.
- It occurs across much of North America and parts of Asia.
Ghost pipe is relevant to Canadian readers because it occurs in parts of Canada, including southern provinces, and is part of the native forest understory flora of eastern and central regions.
