A new key to the species of Digitaria from Canada, Mexico, Puerto Rico, and the United States is now available at the Intermountain Herbarium at http://utc.usu.edu/keys/Digitaria_espanol/Digitaria_esp.html. English is my native language, so please let me know if you should find any improper or incorrect use of the Spanish language. I welcome your feedback!
Best regards, Pedro Onativia Lake
