Abstract

The subject of weeds, no matter where they occur, is always of perennial interest. They travel apparently from one end of the country to the other. Sometimes they become permanent and sometimes are only transient. Sometimes they persist for a few years and then disappear; of this Lactuca scariola L. and its variety is an illustration.
