I. Introductory Remarks. 
Tur object of the following paper is to state the results of a 
number of observations made by myself during the last eighteen 
years upon certain points in connection with the natural history 
in Britain of the above-named species and its allies. Although 
the facts to which I have to call attention are not altogether ne" 
and unknown, they are, at least, unfamiliar to many botanists 
and misunderstood by most. . 
The five British members of the genus Primula, though readily 
distinguishable from each other when found under normal con 
ditions, present many perplexing intermediate forms due to
