106. B. TBOTORLTM L.

This grass was first noticed in the City on the S. E. corner of 

 Union St. and Wealthy Ave. in 1894,by C. W.Fallass. This is the 

 first station reported in the State. The circumstances attending 

 its appearance were carefully looked up by R. E. Matteson who 

 reports the following: "The grass appeared shortly after a fruit 

 dealer whose fruits were largely imported from Italy, occupied 

 the barn on an adjoining lot. It was his custom to brush out his 

 wagon while crossing this lot." 



This is a common grass in Southern Europe, and as it made 

 its appearance immediately after the occupancy of the barn by 

 the fruit dealer, and in such abundance, it seems conclusive that 

 it must have been brought here in the packing material. When 

 discovered it covered the lot and was confined to it. The wind 

 carries the light feathery spikelets and spreads it with great 

 rapidity; from this lot it has spread to all parts of the City, and 

 is now invading the surrounding country.
