 Engene to llic coast. Very c* nunon ab;.nt Walton; also ob- 

 served along sandy roadsides at Newj^ort. 



62 Senecio Jacobaea L. On ballast, Linnton. 



63 Carduus nutans L. Well cstablislud on ballast, 

 Li nil to 11. 



The ballast heaps at Linnton are still far from cxhanslcd. 

 Several plants were collected there which en acconnt of inuna- 

 ture or imperfect specimens could not be satisfactorily deter- 

 mined. A uer)- e\ident species of Desriiodiitvi^ a geuus not ]')re- 

 viously reported from Oregon, was collected, showing neither 

 flowers nor fruit. A piickl)- Conij^o.'-ite of the tribe Cynareae, 

 with yellow flowers, baffled all attempts, but was provisionally 

 referred by Mr. Macbiidc to Consinin. Anoilier unknown Com- 

 posite of the tribe Anthemeae seemed very near to Cotiila. Still 

 another had the asi)ect of a stem less Sciiecio^ but coiild not be 

 determined on account of the impeifcct condition of the speci- 

 men. It is hoped that collectors will devote more attention to 

 this very interesting station. Additions are constantly being 

 made, and some of them seem in a fair way to become perma- 

 nent residents of the slate. A careful study of the introduc-ed 

 plants of Oregon would be cf distinct value to students of our 

 northwestern flora.
