Hart— Oy? the Flora of Lamhaij Inland. 673 



The Lambay flora is a very natural one ; there is little cultivation, 

 and the introduced plants are few in number, sparingly established, 

 and, as I think, easily detected. Disregarding several sub-species or 

 varieties, the flora consists of 291 flowering plants and ferns, of which 

 33 species are probably not native.
