Extract

Medusahead, Elymus caput-medusae L., an exotic winter annual grass, was introduced into northeastern Washington and probably adjacent Idaho over 50 years ago. Official records show its presence in southwestern Idaho 15 years ago, but ranchers in this area assert that it was present 25 to 30 years ago. Prior to 1950 it was known to infest a few thousand acres in southwestern Idaho and its distribution from 1945 to 1950 appeared rather static.
