be divided into various categories. One simple method of divid- 
ing them is to use their relation to man as the differentiating 
criterion. We then obtain :—(1) followers of man; (2) indifferent 
to man ; (3) shunners of man. 
It is not needful that I should print lists; the field experience 
of all botanists will enable them at once to place the plants they 
the other 10° per cent. In the West of England I know localities 
where the percentages are almost exactly reversed. 
hat I want to demonstrate, with a few illustrations, is that 
shunners of man at times show the most unexpected and eccentric 
ways by appearing naturally in the crowded haunts of men; and 
to draw the logical inference that follows. 
_ Plants that are easily affected by buildings, smoke, drainage, 
sewage, cultivation, manuring, close cropping, &c., soon vacate the 
neighbourhood of man and his varied occupations in his daily 
round of work. For my purpose it is sufficient to say, water and 
hog plants, and the Filices generally, as an order, are good illus- 
trations of shunners of man. great number of exceptions to 
the usual rule in this respect could be named. I will, however, 
select three from my budget of notes on this subject, about which 
I believe there can be no mistake. 
Phyllitis Scolopendrium Newm. i 
Lincolnshire, if it be truly areal at all in this county, for at 
resent I cannot say, as I have not yet studied it fully in all its 
im s not k grown in the open there. The 
nearest local-areal habitats, if they are such, are twenty miles on 
the west, and thirty on the east and south: The plant is now 
ead, and has left no successors, but there are leaves from it in 
the county herbarium. 
may be urged that this is an exceptional case. If so, what 
are we to make of my next illustration? The late Rev: Clennell 
Wilkinson, Rector of Toft-Newton, had lived many years in Pem-
