Bristly dogstail grass

Cynosurus echinatus is a member of the Poaceae family and is commonly known as bristly dogstail grass. It is native to southern Europe and has been introduced to various regions, including the Americas and Australia, where it is occasionally classified as a weed. The plant is an annual grass with a height range of 10 to 50 cm. The inflorescence consists of a rounded or oval cluster of spikelets, and the fertile spikelet is characterized by an awn up to 1 cm in length. The awns are densely packed, creating a bristly, hairy appearance in the inflorescence. The species was first described in 1753 by L. The typification of the species has been discussed in botanical literature, with some proposed type specimens not being formally accepted.
