NOTE ABOUT THE PRIMULA VARIABILIS, Goup. 
There has been much discussion in France concerning a plant called 
Primula variabilis, some observers believing it to be a truly distinct 
species, and others considering it as a hybrid between P. veris and 
P. vulgaris. It seems to be far from uncommon in France, inhabiting 
places where the above-named plants grow ; but does not appear ever 
to have been noticed without the companionship of both of them. It 
is true that M. de Rochebrune states (Bull. Soc. Bot. de Fr. viii. 689) 
that he has found P. variabilis in a place where the P. vulgaris does 
not grow, and in others where P. veris is not found; but M. Godron 
„has shown (Bull. x. 178) that the plant called P. variabilis by M. de 
Rochebrune is in reality the true P. elatior (J acq.). 
The result of the discussion in France seems to be that the P. varia- 
_Gilis is a hybrid between the Primrose and Cowslip, and that it is very 
variable in form, according as it approaches one or the other of its 
parents, 
It is remarkable that the very same question agitated our botanists 
a few years since; but being discussed in works little known out of 
England, the same results have had to be arrived at independently by 
Continental observers. Most of that discussion will be found in the
