Overview

Galium tricornutum is a species of flowering plant in the coffee family known by the common names rough corn bedstraw, roughfruit corn bedstraw, and corn cleavers. It is widespread across most of Europe plus northern Africa and southern Asia, from Norway, Portugal and Morocco to China. It is also naturalized in Australia, the Canary Islands, Mauritius, Madeira, Réunion, Brazil, Argentina, and scattered locales in North America.

Corn Cleavers (Galium tricornutum) is critically endangered primarily due to the intensification of agricultural practices and widespread use of herbicides that have eliminated this arable weed from most of its former range. The species has experienced severe population declines across Europe as traditional farming methods have been replaced by modern intensive agriculture with improved seed cleaning and chemical weed control.
