Linaria Minor (L.) Desf., a small European species, seems to have become locally abundant in railroad ballast in the vicinity of Iowa City. Specimens in the Herbarium of the State University of Iowa show that it was collected in 1932 by W. J. Himmel, and in 1942 by G. W. Martin. In 1944 it was very abundant between the ties of the Crandic interurban line and of the Rock Island line south of the Iowa City Airport. There seems to be no previous reference to this species in Johnson County. Neither Fitzpatrick (2) nor Somes (3) mention it, but Cratty (1) lists it as "rare, Chickasaw County". The plant should be looked for elsewhere in Iowa.
