The "Lesser Bullrush" is a common term used to refer to Typha angustifolia, a perennial flowering plant species in the family Typhaceae. However, there are other synonyms used for this plant, such as Narrow-leaved Cattail, Lesser Reedmace, and Lesser Cattail. These synonyms reflect the plant's physical characteristics, such as its narrow leaves, which in turn differentiate it from the Common Cattail plant species. The Lesser Bullrush is a common sight in marshes, ponds and slow-moving streams across the Northern Hemisphere where it performs vital ecological roles, such as providing habitat for wildlife and removing excess nutrients from water.
