SPECIES NOT BEFORE REPORTED . 



Sisymbrium altissimum Z. 



In a newly seeded meadow. Vaughns, Washington co. June. 

 S H. Burnham. This is an introduced plant whose seeds were prob- 

 ably mixed with the grass or clover seed used. It has been introduced 

 into some of the western states where it is becoming a very trouble- 

 some weed. It is 2 to 4 feet tall when well grown. It branches freely 

 and when old and dry it is liable to be broken from its base and rolled 

 over the ground Uke a tumble weed, the wind driving it about and scat- 

 tering its seeds wherever it goes.
