Several of the above, and some others which might be adduced,

decreasing species belong to the English type or are ‘ine 
English,” the der being mostly British species which 
probably require more nd less rain than rm Donegal 
fain ‘cchieehicis to this in thei increasing list, Carduus pratensis being 
the = * otable one. Highland, Northern, and Atlantic species 
all increase in the western parts of the county, both in number an

the larger families, Umbellifere and Carices seem to fail most in

In contrasting the flora east and west of Lough Foyle, there is 
little more 3 be said than that the variety of species as we pas 
east steadily increases. I am not going to enter into this a ae 
and Hordeum murinum; Scilla verna is also found there; an 
noticed that others which have barely found their way across” 
Lough Foyle are abundant on its eastern side, as Trifolium arvense 
and ies 4 anglica; while colonists, weeds of cultivation, and 
species of Watson’s Tosh type of distribution become more 
prevalent.
