Denizen. Littoral. British botanists appear disposed 

 to admit the common cabbage among our native plants, 

 with Uttle or no hesitation. It has certainly become well 

 established in many places, and may be an aboriginal in 

 some of them ; but I fear that the majority of recorded ha- 

 bitats assume a suspicious appeai'ance, either on the spot 

 or in description. Inland localities, about old castles and 

 towns, may surely be rejected, in the case of a plant so 

 long and imiversally cultivated ; for example, the rocks 

 about Stirling Castle. Several of the coast locaUties also 

 are on cliffs close by towns and castles ; as those of Pen- 

 zance and Scarborough. And though some few, more 

 likely to be native habitats, may still remain, I cannot 

 avoid regarding these with doubt. The marvel appears to 

 myself to be, not that the cabbage should have become 

 wild in a few out-of-the-way places ; but that it should 

 have become wild in so few of such places. It may be in- 

 digenous on the south and west coasts.
