Ser LEMENLT LO PRORA 
ORCADENSIS: 
HIS supplement has been rendered necessary 
owing to the amount of valuable botanical 
work done during the summer and autumn of 1912 
and 1913 by Col. H. H. Johnston, C.B., D.Se, F.LS., 
who has very kindly submitted his list of rare plants 
and new discoveries to me and allowed me to make 
use of them at my discretion. I have selected those 
which give new localities, confirm the discoveries of 
earlier botanists, and add new species, but especially 
new varieties, to the list. 
It has been suggested to me that I should draw 
the attention of botanists, proprietors, and lovers of 
flowers generally to the nefarious practice—very rare, 
I am glad to say—of digging up rare plants for sale 
to florists and others. The mere mention of this 
practice, I feel sure, will be enough to discourage 
and reduce it to a minimum. When we botanists 
dig up two or three rare plants for our herbariums, 
or for experimental work in our gardens, we believe 
it to be for the good of Science generally, and quite 
different from wholesale eradication of rare plants for 
the sake of a trifling gain.
