FLOWERING PLANTS. 



1. Agropyron occidentale Scribn. (A. Spicutum L. & L.) Colorado Blue- 



stem. Tippecanoe County. 

 This species is not listed in Bi-itton and Brown, but may be found in 

 the revised edition of Bulletin 17 of Division of Agrostology, United States 

 Depaa-tment of Agriculture, p. 298, 1901. According to Scribner it is found 

 "in diT or moist soil, Wisconsin to Iowa, and westward to Washing- 

 ton, Texas and Arizona." It was found in abundance by the writer along 

 the Wabash and Monon railroads south of Lafayette, in diy. gravelly soil. 

 Its introduction into the State is doubtless due to the railroads.

 other station noted.

canoe County. 

 This plant was collected in sandy bottom land along the W^ea Creek,

 stream from the W'abash railroad bridge. It is probable that it owes its 

 introduction into the State to the railroad. Not very abundant. Of this
