Excerpt from A List of Plants Growing Without Cultivation in Franklin, Hampshire and Hampden Counties, MassachusettsImpure seed is the most important factor in the introduction of harmless and noxious species, and from 75 to 100 or more different species may occur in a particular sample or lot of grass seed. The impurities run from 5 to 25 per cent or more, and although frequently harmless, 10 or 15 per cent of noxious weeds are sometimes present in grass or clover seed. Since seed are sent from all over the United States and imported from foreign countries, it follows that a great variety of plants may be introduced into a particular region. Black medick, Canada thistle, charlock, chicory, crabgrass, chickweed, dod der, various docks and plantains, green foxtail, goosefoot, lady's thumb, ragweed, sheep sorrel, wild carrot, witch grass, yellow foxtail and many others constitute the principal impurities in seed. Dame and Collins, ' in their Flora of Middlesex county, enumerate 460 naturalized and adventive species and varieties which have become more or less established in that region.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
