About Cynosurus echinatus L.
Cynosurus echinatus L. is a grass species that holds the common names bristly dogstail grass, rough dog's-tail, and hedgehog dogtail. It is native to southern Europe. It has been introduced as a species to the Americas and Australia, where it sometimes grows as a noxious weed. In Chile, an herbicide-resistant strain of this grass grows as a weed in canola and wheat fields. This grass is an annual that grows between 10 and 50 centimeters tall. Its inflorescence takes the form of a rounded or oval cluster, or a series of clusters, of spikelets. Fertile spikelets produce an awn that can reach up to one centimeter long. When the awns clump closely together into a tuft, they give the inflorescence its characteristic bristly, hairy appearance.
