Putnam and Marion counties. In all the localities which have come under 

 my observation this is truly a railroad weed. (State Catalogue, p. 733, 

 Proc. Ind. Acad. Sci. 1904: 223.) 



35. Fumaria officinalis L. Fumitory. 



Putnam County. Previously reported only from the eastern part of 

 the State. (State Catalogue, p. 763.) 



*36. Lepidium campestre (L.) R. Br. Field Cress. 

 I Mil nam County, roadsides. 



37. Sisymbrium altissimum L. Tumbling Mustard. 



Hamilton, Putnam and Tippecanoe counties. The first notice of this 

 species in Indiana occurs in the Proceedings of the Academy for 1901 

 (p. 300) where it is reported by Dr. Hessler as "growing along the State 

 Line Railroad east of Lake Cicott, Cass County," and by H. W. Clark 

 from Marshall County. In the Proceedings for 1903 (p. 134) Mr. Smith 

 reports that a single specimen was taken along the Monon Railroad near 

 the State Fair Grounds at Indianapolis. These records point to a wide 

 distribution over the State as a railroad weed. This is one of the most 

 important migrants which has entered our State in recent years, as it is 

 one of the worst weeds of the grain fields of the northwest. So important 

 indeed is this weed that it has received considerable attention both in 

 experiment station and government publications. The station in Tippe- 

 canoe County indicates that the species has probably been brought in with 

 grain, as it is found along the switch by one of the elevators. 



38. Barbarea stricta Andrz. 



This species is admitted to the State Catalogue on the authority of 

 Dr. MacDougal, who reported it from Putnam County, but on account of 

 range probabilities "it is somewhat doubtfully included." (Stale Cata- 

 logue, p. 766.) This species is quite abundant along a small stream in the 

 central part of Piitnam County. 



39. Boripa sinuata (Nutt.) A. S. Hitchcock. 



This species is also admitted to the State Catalogue tentatively on 

 the authority of a specimen collected in Putnam County by Dr. Mac- 

 Dougal. (State Catalogue, p. 766.) This species is well established at a 

 single station on the Big Four Railroad west of Greencastle where it has 

 been able to maintain itself for the past fifteen years.
