composition from plant to plant. Plants which differ in this way are known as chemotypes and a geographical population will generally contain a mix of chemotypes. For example, studies of chemotypes in Greenland, Iceland, Norway, England, Scotland, and Ireland show that chemotypes span those countries rather than being geographically localized. Some of those areas contain greater chemotype diversity than others.
