communicated by Mr. Fraser Robinson as a casual 

 from Hull Docks. 



Agrostis scabra, Willd. Mr. Marshall recorded this 

 plant as " apparently quite established on the West 

 Highland railway banks between Tulloch and Fersig." 

 The discoverer thought it might have been introduced 

 with timber from Canada. It is a common native in 

 the woods of that country, and its seeds are frequently 

 found adhering to trees in the autumn. 



.Alopecurus agrestis, L. Native of grassy places in 

 Central and Southern Europe, only reaching the extreme 

 north-west as a cornfield weed. In England it is well 

 established in cultivated and waste ground, and was

 foreign grain. It becomes scarcer and more casual 

 northwards. 



Alopecurus utriculatus, Pers. A native of Central 

 and Southern Europe. It has been introduced as a 

 casual into England, doubtless with foreign hay or corn.

 close resemblance.
