Description
This plant grows up to 35 cm (12 in) tall, with one simple stem bearing evergreen, shiny, toothed leaves in opposite pairs or whorls of 3-5 (and sometimes more) along the stem. Leaves have a slightly spiny serrulate margin starting close to the base, and range from 1 ½ to 2 ½ inches long (or longer) with a typically oblanceolate shape. Flowers range from white to pink, produced in a small umbel of 4–8 together. The filaments have a roundish expansion at the base, bearing hairs along the margin only. In comparison, the closely related C. menziesii bears hairs on the back of the filament's expansion as well.[2]
Ecology
Although it has green leaves year-round, it receives a significant portion of its nutrition from fungi in the soil (that is, it is a partial myco-heterotroph, which is not surprising as related plants, such as Pyrola, are partial or full myco-heterotrophs).[3]
Taxonomy
There are four subspecies:
- Chimaphila umbellata subsp. umbellata – Europe, Asia
- Chimaphila umbellata subsp. acuta – southwestern North America
- Chimaphila umbellata subsp. cisatlantica – northeastern North America
- Chimaphila umbellata subsp. occidentalis – northwestern North America
Uses
Some Plateau Indian tribes used a boil of prince's pine to treat tuberculosis.[4]
The twentieth century Appalachian folk healer Clarence "Catfish" Gray, "Man of the Woods", credited pipsissewa with curing his own heart problems and included it in his 15 herb cure-all "bitters."[5]
It can reportedly be used as a flavoring in candy and soft drinks, particularly root beer.[6]
The roots and leaves of Chimaphila umbellata can be boiled to create tea.[7]
Recent investigations show the anti-proliferative effect of Chimaphila umbellata in human breast cancer cells (MCF-7). [8]
Name
"Pipsissewa" is a Cree name meaning "It-breaks-into-small-pieces".
