Abstract

Pennisetum petiolare, a grass native to the Sudan and Ethiopia and never previously reported from North America, occurred in a lawn in Ames, Iowa. The source of the seed was contaminated Niger thistle (Guizotia abyssinica) seed used in a bird feeder directly above the location of the plant. The occurrence of at least 15 other seeds or fruits as contaminants in the sample indicates that Niger thistle seed may serve as a medium for the introduction of weed seed into the United States.
