neighbourhood of old castles, ruins of religious houses, and 

 such spots as can scarcely fail to awaken some suspicion 

 that its present existence there may have been owing to 

 former cultivation. But besides these localities, there are 

 others on chffs, and in neglected nooks near the sea shores, 

 which assume more of a natm-al aspect. I am disposed to 

 consider it native in the more southerly provinces, but only 

 naturalized in Scotland and the northern provinces of Eng- 

 land.

Native. Paludal. Almost too partial in its ai-ea, and 

 too low in its census, to be fairly referrible to the British 

 type, and yet nearer to that type than to any other. It is 

 somewhat remarkable for a person who has collected plants 

 in so many different and distant coimties, that I should have 

 never j^et seen this species in a living state ; my herbarium 

 being indebted to other botanists for all the examples of the 

 present species, which are contained therein. If, therefore, 

 I should trust to my own individual experience, it would be 

 entered as one among our rai'est plants ; and yet, such is 

 not the case. This is a decided instance of the inadequacy 

 of individual experience, as a test of the rarity and fre- 

 quency of plants.
