Phleum pratense is a type of grass species that goes by a variety of synonyms. Commonly referred to as Timothy grass, this species is also known by other names such as herdgrass, cat's tail, meadow cat's tail, and herd's grass. Other related synonyms include foxtail timothy, perennial Timothy, and common Timothy. The grass is native to Europe but has since spread to other parts of the world and is now widely cultivated for hay and pasture. Timothy grass is known for its high nutritional value and is commonly used as a forage crop for livestock, particularly horses. With its various specific names, it is easy to see how the name "Phleum Pratense" remains an understated and yet persistent component of agricultural and botanical science.
