4. Accidental introductions with imports (in wool, in Esparto 
grass, &c., or in other commercial produce), in ballast, or in 
agricultural operations. Operations of magnitude—e.g., 
making railways, or war, may also introduce plants. 
5. A few appear sporadically, their mode of introduction being 
doubtful, but probably not due to human agency. 
In the list, for completeness, will be included the names of all 
the ascertained species introduced in any of the above ways into 
the N.E. of Scotland, even when already mentioned in the 
preceding paper. Where only the name is given, without other 
particulars, the reader is referred to that paper for further 
information about the plant. Specimens of all the species men- 
tioned below are included in a herbarium formed by myself in 
this district, except those quoted solely from the ‘ Botanist’s 
Guide.”
