which, though not indigenous to the North Western counties of 
England, are yet included in the London Catalogue of British 
Plants. 
With the exception of the Silloth station, I am individually 
responsible for the lists which accompany the present notes. At 
Silloth I have received courteous and able assistance from Dr. 
Leitch of that place, who, besides his acknowledged ability as an 
exponent of botanical science, has the great advantage of being 
constantly on the spot, and able at all times to examine and report 
on the occurrence of anything unusual in the plant line. From 
the Rev. Hilderic Friend, F.L.S., late of Carlisle, I have also 
received useful and accurate information ; and I deeply regret his 
departure from the neighbourhood. Last, but by no means least, 
I must acknowledge the ready and cheerful assistance of Miss E. J. 
Glaister, of Blackdyke, Silloth, and her brother, whose names. must 
be associated in my memory with many a seaside ramble enjoyed in 
their congenial society. I must travel yet further afield in my 
acknowledgments, and express our joint obligations to Mr. J. G. 
Baker, F.R.S., of the Herbarium at Kew Gardens, London, for 
his courtesy in identifying specimens regarding which any doubts 
existed. His services in that respect have been invaluable, and 
we justly congratulate ourselves on having been fortunate enough 
to receive the benefit of his almost world-wide experience. 
The lists which are appended to these remarks must not be 
considered as anything but an approximate catalogue of the species 
that have appeared from time to time during the last fifteen or 
twenty years. From the very exposed situation of the refuse 
heaps, it will easily be understood how readily any attractive 
flower would be appropriated as an addition to a child’s- or grown- 
up person’s- bouquet, and so fail to be noticed by an occasional 
visitor. 
Nor is it to be supposed that these adventive species will (except 
in very rare instances) become acclimatized or established here. 
Take Maryport as an illustration. The ground surface there has 
been covered with successive layers of ballast, during the seven 
years of my residence at Flimby or Workington, each layer obliter-
